Query for "usb-max-interfaces" #26

Closed tangyanli closed 3 years ago

tangyanli commented 3 years ago

Hi, Alexander:

This is only a query, not issue.

I saw you added the "usb-max-interfaces" configuration, although you say it is quirks for "HP ScanJet Pro 4500 fn1". But I want to use airscan + Canon printer driver concurrently (As I said in the https://github.com/alexpevzner/sane-airscan/issues/68#issuecomment-717829682), so I think it is a chance for me.

I did test: Add below setting in /usr/share/ipp-usb/quirks/default.conf

 [Canon MF745C/746C]
usb-max-interfaces = 1

After plug the USB printer, I first test airscan, it works well. Then I add the Canon printer driver whose device uri is "usb://Canon/MF745C/746C%20UFR%20II?serial=f4a997cf9d6c&interface=1", it can also print. But after printing, the airscan cannot work. I use below command to test the printer, it has no response. curl http://localhost:60000/eSCL/ScannerCapabilities

Then I unplug and re-plug the USB printer, the airscan can work again.

I cannot guess the reason, is it the printer's issue or can ipp-usb fix it?

Some additional information, MF745C has 3 interfaces. I guess Interface 0 is for scanner, interface 1 is for printer and interface 2 is for fax. And Interface 0 has three endpoints, interface 1 has two endpoints.

Hi Tess,

glad to hear from you again :-)

Looks like Canon printer driver does something which causes firmware to loose synchronization with the IPP over USB "session", which causes ipp-usb to fail.

Which I can definitely tell, after reading the log you've supplied, is that ipp-usb and Canon printer driver use different USB interfaces, so it is not interference of commands sent by ipp-usb and printer driver to the same interface, but rather a side effect or some command that Canon driver has sent to its interface.

This is unlikely that it can be somehow fixed in the ipp-usb

Hi, Alexander:

Glad to receive from you again :)

Then I give up to configure the “usb-max-interfaces”.
