Hi,

I can confirm this issue with a different printer with version 0.9.20. @alexpevzner, is there a reason why you check in usbcommon.go:IsIppOverUsb() for Proto==4? According to [1] this is a reserved value. At least my old Samsung ML-1520 delivers a '2' and thus is not recognized as printer.

I like your post. at least i see that i'm not the only one to have this problem.

in order to help dev's, can you explain me how to debug the ipp-usb package and provide useful information for its rewriting or troubleshooting ?

I don't know anything about debugging or programming.

if you prefer that I leave this to others, tell me. it's probably very difficult and I think I don't have the level but I'm willing to learn the little I can.

friendly, respectfully, alain.

p.s.: printer is H.P. Envy 5536 (recognized like a 5530 series)

"Proto==4" is IPP interface, if the "Proto==2", means the device doesn't support IPP over USB specification. More details you can refer the IPP over USB specification.

i've just tested ipp-usb with 5.17 kernel . do not work anymore . i made some errors ? i forgot something ? could you help me for tests and debugging ?

thanks , friendly , respectfully . alain .

@BELLECalain do all versions of ipp-usb not work with kernel 5.17? Or is it only the new 0.9.20 version?

Thanks, @tangyanli USB printing (7/1/x) has currently 4 different protocols: x = 1 is mon-directional streaming, x = 2 is bi-directional streaming, x = 3 is IEEE-1284 packaet format (AFAIK only used by HPLIP currently), x = 4 is IPP-over-USB.

IPP-over-USB devices (7/1/4) ALWAYS print and scan driverless. For printing this means at least one of AirPrint, IPP Everywhere, Mopria, or Wi-Fi Direct Print is supported (or at least IPP 2.0 plus understanding at least one page description language of PDF, Apple Raster/URF, PWG Raster, PCLm), for scanning this means to understand at least one of eSCL and WSD/WS Scan.

Hi @BELLECalain,

may I ask you to collect a whole set of log files (/var/log/ipp-usb/*) when running on the 5.17.x kernel? It will be better if before testing you will erase old log files, so there will be less mess between old and new logs.

Hello @alexpevzner @BELLECalain provided four logs to the Debian bug report at https://lists.debian.org/debian-printing/2022/04/msg00071.html.

I have attached the fourth one.

Hi @debiantriage, nice to hear from you and thanks!

libusb_bulk_transfer: Operation timed out

Looks like libusb is broken on 5.17.x this kernel (or on this distro). It would be nice to retry wth apparmor/selinux disabled (depending on a distro).

@.***:~$ sudo aptitude search ~b

@.***:~$ sudo apt-get check Lecture des listes de paquets... Fait Construction de l'arbre des dépendances... Fait Lecture des informations d'état... Fait

it seems there is no broken packages

I don't mean the package itself (i.e., files the package consist of) is broken. I mean, the package's functionality is broken.

One of possible reasons is the apparmor/selinux settings. It makes sense to temporary disable apparmor/selinux and to retry. If it will help, it will seriously localise the source of the problem.

What exactly your Linux use, depends on a distro. Fedora and similar love to use selinix. Ubuntu loves apparmor. I don't know about other distros.

@BELLECalain A quick way to do as @alexpevzner suggests is to purge apparmor and reboot. It is easily reinstalled.

As a separate test, would you try a different USB port?

uninstalled apparmor and reboot .

system-config-printer do not work better and do not recognize my printer .

with the 0.9.20-1 ipp-usb package , it seems not to work better than with the stable one

(ok for stable version) .

saw this :

https://wiki.debian.org/AppArmor/HowToUse#Enable_AppArmor

and did this before uninstall :

echo 'GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT apparmor=0"' \ | sudo tee /etc/default/grub.d/apparmor.cfg

now deleted file .cfg

i am reinstalling apparmor .

do i have to do this : ?

echo 'GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT apparmor=1 security=apparmor"' \ | sudo tee /etc/default/grub.d/apparmor.cfg

thanks .

i don't know if using another usb port will be useless .

like using the printer with the stable version of ipp-usb (instead of the sid version) is ok .

libusb_bulk_transfer: Operation timed out

Bearing in mind that my understanding of ipp-usb internals is very tenuous, may I inquire whether the following (from #32) is worth consisideration?

Regarding DevInitTimeout, I can add device-specific quirk to selectiverly increase this timeout on devices that require it, but I don't want to increase it for all devices, because if initialization stuck, it prevents ipp-usb from normal shutdown, and long timeout here is really annying.

My thoughts have turned to seeing issue like this one and #33 as having firmware bugs involved, although I am still perplexed by @BELLECalain regaining printing and scanning by downgrading ipp-usb.

Hi All,

I've just tested ipp-usb 0.9.20 with 5.17.4 kernel at Fedora 35 with Kyocera ECOSYS M2040dn. It works pretty well. So seems the problem is not in the kernel version.

Hi!

I'm trying to understand the situation with this issue, and I must confess, I'm completely confused. Too many information, sometimes controverting, split into small pieces around entire Internet.

Now I'm trying to bring all parts together.

First questions:

Is there any configuration (combination of kernel version and ipp-usb version), that definitely works?
Is there any configuration, that definitely doesn't work?
When it works, does it work reliable or time to time?
When it doesn't work, doesn't it work always or time to time?

hello alexander pevzner and brian potkin .

I will try to answer your 4 questions clearly:

1) combinations that work :

stable kernel with stable ipp-usb
kernel testing / sid with ipp-usb stable version

2) combinations that definitely don't work:
kernel testing / sid with ipp-usb (testing / sid version)

once my printer is plugged , system-config-printer do not recognize it .

i can not print even a test page . and never see the printer icon .

3) when it works, it works constantly. system-config-printer is constantly fully functional.

once i plug in my printer (or power it on) , after a very short delay ,

system-config-printer recognize it and i can print a test page and my documents .

i see the printer icon and it is fully functional .

4) when it doesn't work, it's definitive. it doesn't work.

system-config-printer never recognize it and i can not print even a test page

apparmor seems to do nothing with the testing/sid version of ipp-usb .

I answered your questions as you wanted? Did it help you ?

friendly, respectfully,

alain.

nb: for instance , i am working with the stable version of ipp-usb and all is nearly perfect .

under 5.17 kernel . my system is constantly up-to-date (sid) .

in case of , sorry for the flood .

What is unstable kernel and unstable ipp-usb?

@alexpevzner On the present Debian unstable ipp-usb is 0.9.20 and @BELLECalain was using kernel version 5.16.0-6-amd64 when the bug was reported. He also reports that downgrading to ipp-usb 0.9.17 brings back printing and scanning.

Hi,

I've reviewed all changes between 0.9.17 and 0.9.20. The whole list is following:

Some changes in documentation. Should not be relevant
Snap port. Should not be relevant
Loading quirks from the alternative location, /etc/ipp-usb/quirks/*.conf, Should not be relevant
Some tweaks around DNS-SD advertising. Should not be relevant.
Added usb-max-interfaces quirk and applied to the HP OfficeJet Pro 8730 device. Should not be relevant.
Fax is not probed by sending Get-Printer-Attributes request to the /ipp/faxout if device basic capabilities, obtained from the USB side, doesn't include FAX bit (see #32). Should not be relevant.
While requesting printer attributes with the Get-Printer-Attributes request, instead of requesting "all", only really needed attributes is requested, because some enterprise-class HP devices return so huge amount of information, so retrieving it takes too much time (see #32).
Fixed USB 3.0 support by using I/O buffer size which is 1024*N (was 512*N) while reading from USB. Should not be relevant.

There are literally no other changes between 0.9.17 and 0.9.20.

None of these changes look suspicious. Only 6) and 7) are visible from the USB side.

If somebody has a problematic device (HP-ENVY-5530-series), able to build the ipp-usb locally (this is really easy) and willing to help, we can try to debug this issue by temporary disabling effect of these changes directly in the ipp-usb code. It it will help, I can add a corresponding quirk

tried ro compile ipp-usb git version . i didn't succed . I have very big problems with the prerequisites. I don't know what to install and how to compile the sources.

https://github.com/OpenPrinting/ipp-usb

if someone can help me .

respecrfully , friendly , alain .

tried the ipp-usb/testing,unstable 0.9.20-1+b1 amd64

do not seems to work any more .

in case of , could you explain me the procedure to do the tests ? don't think i made an error but i wonder .

put again the "debian stable" version

printer is not recognized in system-config-printer and do not work at all . i can not shut it down . and i have to manually unplug it . do these lines can help for debugging ?

Looks that device hangs during probing for fax at first attempt of the ipp-usb to start and doesn't respond at all during second attempts.

Did you unplug the device between these two attempts?

Does the device has faxing facilities?

Do you still need the building instructions?

what i did :

by default, I left the debian stable version of ipp-usb in place and froze it (apt-mark hold)

then, I compiled the git sources. and finally, I launched the git version of ipp-usb. (what you see) I made an error(s) ?

n.b.: when I copied this I did not touch the printer. I pressed its on/off button: I couldn't turn it off.

i don't know if my printer has fax capabilities . i never used it for that . and i don't know if the option exists on it .

no , i succeded to compile the git sources . very thanks but's that is no more necesary to help me to compile these sources .i made it .

Hi @BELLECalain,

I have a hypothesis, that problems with your device is caused by attempt to probe faxing facilities. If you have successfully compiled a git version of the ipp-usb, probing for fax can be disabled using quirks.

Please, add the following lines to the /usr/share/ipp-usb/quirks/HP.conf file:

[HP ENVY 5530 series]
  disable-fax = true

If it helps, please, let me know: I will add this quirk to the distribution.

BTW, does your device actually have a fax unit?

I looked at the printer : i didn't saw any fax option .

alain@sid:~$ cat /usr/share/ipp-usb/quirks/HP.conf
## ipp-usb quirks file -- quirks for HP devices

[HP LaserJet MFP M28-M31]
  http-connection = keep-alive

[HP OfficeJet Pro 8730]
  http-connection = close

[HP ENVY 5530 series]
  disable-fax = true

i power on my printer and i test it :

alain@sid:~/Téléchargements/ipp-usb$ sudo ./ipp-usb 
[sudo] Mot de passe de alain : 
ipp-usb already running

system-config-printer recognize my printer and i can print a test page .

ipp-usb already running

You probably test with the ipp-usb, installed as a package. Can you temporary kill it (killall ipp-usb), or even temporary uninstall, and run ipp-usb manually from the directory where you have build it?

Or alternatively you can temporary replace /usr/sbin/ipp-usb with the ipp-usb file that you have build from sources.

printer powered on , ipp-usb (debian stable version) frozen :

alain@sid:~/Téléchargements/ipp-usb$ killall ipp-usb

alain@sid:~/Téléchargements/ipp-usb$ sudo killall ipp-usb

i launch manually the git version :

system-config-printer do not recognize my printer .

Device quirks: disable-fax = false

This is wrong, must be true. Probably, I've guessed device name incorrectly.

What ipp-usb check prints?

i noticed that uninstalling ipp-usb also remove the quirks . removing ipp-usb and reinstalling quirks . noticed : removing ipp-usb also remove .../ipp-usb/quirks in /usr/share/ don't know what to do .

Just run ipp-usb from the directory where you've built it, and use quirks located at the ipp-usb-quirks subdirectory of the source tree directory -- ipp-usb loads quirks out of there as well.

updated ipp-usb-quirks in the git repository on my pc .

all worked well . like you see , i was able to print a test page . the quirk you told me to add seems to be very usefull .

what to do now ? to my side ? and to your side ? trying to make install from the git sources :

 alain@sid:~/Téléchargements/ipp-usb$ sudo make install
[sudo] Mot de passe de alain : 
gotags -R . > tags
/bin/sh: 1: gotags: not found
make: [Makefile:12 : all] Erreur 127 (ignorée)
go build -ldflags "-s -w" -tags nethttpomithttp2
error obtaining VCS status: exit status 128
    Use -buildvcs=false to disable VCS stamping.
make: *** [Makefile:13 : all] Erreur 1

don't know what to do ?

I think, the simplest way for you will be:

Install latest "official" ipp-usb
Replace /usr/sbin/ipp-usb with the binary you've built
Replace /usr/share/ipp-usb/quirks/HP.conf with your updated version
Unplug the printer and plug it back, so ipp-usb will restart

Next release of the ipp-usb will include this quirk. I plan to create this release in few days (waiting for #9 in case it will bring one more useful quirk), and then it will take some time to propagate into the distro you use

updated ipp-usb-quirks in the git repository on my pc .

# eSCL requests hangs on this device, if both USB interfaces are

# HP Photosmart 6520 series doesn't implement true faxing,

unfreezing ipp-usb and uninstalling it .

all worked well . like you see , i was able to print a test page . the quirk you told me to add seems to be very usefull .

what to do now ? to my side ? and to your side ? trying to make install from the git sources :

 alain@sid:~/Téléchargements/ipp-usb$ sudo make install
[sudo] Mot de passe de alain : 
gotags -R . > tags
/bin/sh: 1: gotags: not found
make: [Makefile:12 : all] Erreur 127 (ignorée)
go build -ldflags "-s -w" -tags nethttpomithttp2
error obtaining VCS status: exit status 128
    Use -buildvcs=false to disable VCS stamping.
make: *** [Makefile:13 : all] Erreur 1

don't know what to do ?

Install latest "official" ipp-usb (done, version 0.9.20-1+b1 installed) Replace /usr/sbin/ipp-usb with the binary you've built (done) Replace /usr/share/ipp-usb/quirks/HP.conf with your updated version (done) Unplug the printer and plug it back, so ipp-usb will restart (done and now , testing) : all is ok .

what was the problem ? what was the error ? how did you solve it ?

Next release of the ipp-usb will include this quirk. I plan to create this release in few days (waiting for https://github.com/OpenPrinting/ipp-usb/issues/9 in case it will bring one more useful quirk), and then it will take some time to propagate into the distro you use

thanks a lot . and again , sorry for the flood .

friendly , respectfully , alain .

what was the problem ? what was the error ? how did you solve it ?

Your printer reports, via USB device capabilities, that it has fax unit, but sometimes hangs when ipp-usb attempts to load fax parameters.

I have disabled probing for fax, using the quirk, and the problem dissipated (well, I hope. Actually, we have not tested for enough time to be sure).

BTW, does your printer actually have a fax unit?

Please use this version for few days. If everything still will be OK, I will consider that the problem is finally solved.

Does my printer have a fax unit?

no, not at all. or else, I don't know where it is. I have never used such a device. I never use it. I know it exists, but my printer is a "consumer" printer and I don't know if it's made for it . I'm not sure. Not sure at all.

I don't have a fax unit. On the other hand, it is well marked: "print / scan / copy / photo / web". I suspect what this means but I don't know more. It is a usb / wifi printer. but the wifi works very badly (it's its weak point), so it's more like a classic usb printer.

Anyway, thank you for the support and the troubleshooting. I hope I haven't been too much trouble. and sorry for the flood .

Translated with www.DeepL.com/Translator (free version)

n.b.: waiting for the next version of the package . currently using the git binary with the updated quirks and the last debian unstable package (0.9.21-1+b1 for sid) . waiting for further developments . thanks . thanks a lot .

To determine whether a printer has a fax unit, check the connectors on the device's back. For fax a phone connector is needed, this is an RJ11 socket, it looks similar to an Ethernet socket but is smaller (6 instead of 8 contacts, often only the center 2 of them actually used). Usually there are 2 such sockets so that in countries where the wall socket for the phone only has a single slot, the phone is connected to the second RJ11 of the fax device. Also in the box you find a phone cable, RJ11 on one end and a phone plug specific to your country on the other end.

But it is possible that HP (or perhaps alo other manufacturers) implement a kind of fax-over-internet. Then the device's firmware reports viua DNS-SD and IPP that the device supports fax, and also accepts appropriate jobs. Internally it sends these jobs to a fax service on the internet which passes the fax on into the phone network as needed (like VoIP telephony).

So also check the front panel menus of your device, the web admin interface, and also the DNS-SD TXT record which the device reports (use avahi-discover to find out what your device shouts into the network).

first , i ran avahi-discover alone without power on the printer . then , i powered on the printer while avahi-discover was running . and , at last , i shut down the printer with avahi-discover still running . now , i post you the results . n.b.: with the last works about ipp-usb . i modified nothing since the solution was found . didn't saw any fax support on my printer . there is only a main plug and a usb plug . that's all . and , in the "front panel" , i didn't saw any fax option .

Thanks. Then it has really no fax ...

Hi Till,

it's the second HP device that claims fax support but have problems in attempt to query its parameters. Previous was HP Photosmart 6520 series; it implements faxing over Internet, and probably hangs when not connected to the Internet.

today , scan test :

alain@sid:~$ scanimage -L

device `escl:http://localhost:60000' is a HP ENVY 5530 series [FE04D6] (USB) platen scanner

device `airscan:e0:HP ENVY 5530 series [FE04D6] (USB)' is a eSCL HP ENVY 5530 series [FE04D6] (USB) ip=127.0.0.1

simple-scan works perfectly .

xsane gives images in black and white while it is set in color. corrected . it was enough to change the input device .

i thank you a lot for the solution you gave me . but i wonder : is my printer too old ? do i have to change it ? or i keep it still a few years ?

but i wonder : is my printer too old ? do i have to change it ?

If your printer does its job for you, why worry?

or i keep it still a few years ?

Printers of this class rarely survive for more that few years. But I don't see any reasons why not to use it until it appeared to be physically broken

May I thank @alexpevzner for the professional, competent and successful treatment of the issue in this long thread. Kudos to @BELLECalain for hanging in there. Our printing system would be very much the poorer without the support of maintainer and users.

Thank you very much, Brian, for your warm words!

I also want to thank you two, @alexpevzner and @BELLECalain for your patience and effort to hunt down this bug and finally find the solving quirk rule. I have observed the long thread and helped a little bit by fixing the formatting of @BELLECalain's messages (please put a line with only three backticks before and after a block of code lines, to prevent the code from being markdown-formatted). This is the way how reporting, investigating, and solving issues should work.
