usb.core.USBError: Entity not found #8

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. python pyAlienFX.py
2. run any USB command (preview, lights off...)

What is the expected output? What do you see instead?

The USB command is not processed and I get a Python error instead.

What version of the product are you using? On what operating system?

I am using the up-to-date git repository (17th November 2012) on Arch Linux 
with Python 2.7.3 and libusb 1.0. My laptop is an Alienware M14x R2.

Please provide any additional information below (Python Error Message if
possible).

Please can you give me the output of the command : lsusb ?

Original comment by ledjfou125 on 18 Nov 2012 at 3:27

GoogleCodeExporter commented 9 years ago 
lsusb gives:

Bus 004 Device 004: ID 187c:0521 Alienware Corporation 

The laptop is detected as a M14XR1, since M14XR1 and R2 share the same VID/PID. 
By the way, I can change the colors with AlienFX Lite (Java GUI).

Can you try to run it as Sudo ? I know that since some update of the Linux 
Kernel controlling USB as to go through sudo for some users ! Can you try ?

Original comment by ledjfou125 on 18 Nov 2012 at 1:13

GoogleCodeExporter commented 9 years ago 
It does not change anything. My user has USB rights and if this were the 
problem, it would probably throw a "usb.core.USBError: Access denied 
(insufficient permissions)" error.

Original comment by chretie...@gmail.com on 18 Nov 2012 at 1:33

GoogleCodeExporter commented 9 years ago 
I know, I just assumed it might help ... I know about the permission error but 
I though maybe who knows ;)

Ok well then let's think about that ... 
So the error occurs on the detatch_kernel ... can you try to comment that line 
? 
line 109 in the file : AlienFX/AlienFXEngine.py

If you have an error : "Can't set the configuration. Error : blablabla" then it 
means your controler is "occupied" normally ... the detach kernel is here so 
that it closes all connections to it so that the driver can take control ...

But that should not help with our issue here ... it is very weird as it does 
work for other people under debian based system (not tested for Arch but there 
should not be any issue ... ) 

It is not a libusb issue I think but I can't be sure ... but you installed it 
so it should work fine ...

Ok a possibility that I see is that under Arch Linux the controller is not 
"mounted" on the 0 interface thus it raise an error. 

So please can you do two things : 

First comment the line 109 and give me the whole output ? 
then also that "might" be usefull can you run the script I attacched ? (please 
put it in the pyAlienFX folder and run it from there !)

First, I realized that this error happens after I click "Preview". Before that, 
if I click lights off for instance, I get:

Sending : Get Status

But if I click preview, I get the "usb.core.USBError: Entity not found" error, 
and if I click lights off again, I also get the "usb.core.USBError: Entity not 
found" error.

If I comment line 109 of AlienFXEngine.py, and choose Lights Off, I get the 
same error as previously:

OK as much as I want to understand this I have no idea why this is happening !

I though of something but it was that ... now ... I have to look deeper ...
I'll check online now ... does it work with previous versions ? especially 0.2 ?

We'll get this to work :D

Ok do you happen to have any other software which could use that USB controller 
? 

Because to be honnest the only way I managed to get the same bug as you is when 
I tried to get the driver two run two instances.

if you ps aux | grep alienfx 
what do you got ?

Moreover the fix I did should have detached any other instances ... 

Can you pull the git and copy past the Whole output I added some "debug print 
msg" on the way ...

Ok that's good news !

Can you try first NOT to launch the Daemon ?
I though you used it without the daemon ! The daemon is buggy yet and I really 
need to recode the whole thing xD (Then some can ask me WHY did I included it 
... )

Anyway can you try without the daemon ? and Give me the whole output again ?
At least it is not as bad as I though :D 

here : 
Kernel Detached (on 1st trial)
CONFIGURATION SET ! (on 1st trial)

I though that I'll never get your computer to do that xD !
Now that I know it can, it's a matter of understanding what's going wrong and I 
might have some ideas ! ;)

But I'll need the debug from pyAlienFX.py alone no daemon, no indicator !

It is funny because the software is following path that aren't suppose to

Ok I corrected :

It works at least partially ! meaning that it can communicate ! No I have to 
see why it is buggy like that xD !
Moreover that is happening only on Arch ...

Hi,

Just to say that I have same issue here...
the strange thing is pyalienFX works at least one time (first time I installed 
one week ago).
Since that no update and it doesn't work anymore ;)

Hi I worked a lot on that problem but the thing is that it has to come from 
Arch Linux last updates ...
But I have no idea which one ... kernel ? LibUSB ? Python ? I do not know and I 
fear I'll have it too soon enought on Ubuntu ... But I don't know what to do 
... maybe you'll find someone on the Arch Linux forum ?

Hi,

I have found a workaround and the source of the problem...

I have followed this idea : if libusb is involved in the bug, why do not use 
the libusb from ubuntu. In fact, using libusb from ubuntu solved the problem.

Here are the things I have done :
- copy libusb-1.0.so.0 from an ubuntu installation (/lib/x86_64-linux-gnu on my 
ubuntu installation)
- in root, I have launched : 
LD_PRELOAD=/path/to/copy/of/ubuntu/lib/libusb-1.0.so.0 pyAlienFX

It works (quicker than on ubuntu, no freeze at all when applying ocnfiguration) 
!

So I think that we know what is the problem...

Hope this help,

BR,

Last information : my ubuntu is 12.04 (with libusb 1.0.9 patched by ubuntu team)
On arch : libusbx 1.0.14

If someone have an Raring ubuntu platform to see if it works... 
libusb 0.1.12-23+nmu1ubuntu1  (strange version number)
libusbx : 1.0.12-2ubuntu1

it's much closer to arch one (libusbx I mean because libusb version is very 
strange in this ubuntu version). I don't know which one is present by default 
on this version (in arch, libusb doesn't exists enaymore I think...)

After this issue affected me I thought it was related to the detection of the 
computer. I think that the detection message should be rewritten to say the 
computer may be R1 or R2. Thanks

Sure, the porblem is just that R1 and R2 are using the same USB controler so 
it's hard to tell which is which but I'll change it to R1/2

Just a FYI, pyAlienfx was working fine on my laptop with Fedora 17, and then 
stopped working when I upgraded to Fedora 19 today. I downloaded the Ubuntu 
libusb.so file from a few posts above, used the LD_PRELOAD trick, and it now 
works fine.

Having the same issue here since upgrading from Xubuntu 13.04 to 13.10.  
LD_PRELOAD trick isn't working for me.  Running latest from git.

Update: I wrote a small patch that appears to fix this issue by commenting out 
one of the attempts at setting a USB configuration.  That one seemed to be 
attempting the set while the device was busy, which caused issues.  Git

I get that error too.  I'll have to look into fixing it sometime.
