Red Hat Bugzilla – Bug 249132
kernels 2.6.22.1-27.fc7 and pilot-link with libusb support
Last modified: 2007-11-30 17:12:10 EST
Description of problem: kernels 2.6.22.1-20.fc7 and 2.6.22.1-27.fc7 make pilot-link with libusb support non-functional Version-Release number of selected component (if applicable): kernel 2.6.22.1-27.fc7 pilot-link-0.12.1 built with libusb support udev-106-4.1.fc7 How reproducible: The same pilot-xfer binary and udev package works with kernel-2.6.21-1.3228.fc7 Steps to Reproduce: 1. Build pilot-link-0.12.1 with libusb support (use './configure --with-python --enable-libusb --enable-conduits --prefix=/opt/pilot-link/' to install it separately from F7 pilot-link package) 2. Connect your PalmOS USB device, press Syncronize button 3. Try '/opt/pilot-link/bin/pilot-xfer -l -p usb:' with kernel-2.6.21-1.3228.fc7, you will get file list in your PDA. 4. Boot 2.6.22.1-27.fc7 and repeat step #3. Nothing happens. Actual results: No connection with PDA Expected results: Information exchange with PDA Additional info: Two files attached. These are fragments from /var/log/message after 'udevcontrol log_priority="debug"'. One is for working case, another is not working.

Sorry I forget to mention that to test this case, you need to blacklist visor module (please, read pilot-link-0.12.1/doc/README.libusb file for more info)
Colleagues, to avoid opening another bug, this bug also applies to F-Spot and digiKam (and possibly other applications) in regard to being able to communicate with USB cameras in PTP mode. With kernel 2.6.21.1-3228 such communication simply works, and with kernel 2.6.22.1-27 it does not. It is _very_ annoying, and is somehow associated with the 2.6.22 kernel. Is there any information I might provide which would assist in its resolution? Or are there any tests which might help (it feels like a permissions issue, but one isn't sure where to start poking first!) Otherwise, I would suggest that the severity should be high, since it probably affects any USB connected peripheral.

It seems that some USB stuff is broken in 2.6.22.1-27. I don't know if it is related or not but with this kernel Nokia E65 cell phone is not mounted anymore when connected with USB data cable in "Data transfer" mode. In FC5 and in F7 with 2.6.21.1-3228 it mounts without a problem. Above are dmesg outputs and / var/log/messages files related to working and nonworking kernels. udevcontrol log_priority="debug" was set for more information.

Sorry, I do not agree that this bug has been marked as a duplicate of 249272. On my computer USB flash drives and CD/DVD drive attached to USB works without a problem. So, this is a separate bug. If you still think that this is a duplicate, please, provide some explanations. Also, please note, this bug was filed earlier, so why THIS bug is duplicate?
(In reply to comment #6) > > *** This bug has been marked as a duplicate of 249272 *** Chuck, I agree with Sergui, this bug is concerned with USB communication to an intelligent peripheral. There is no problem with a USB mass storage device. Robin
Gentlemen, anybody working on that? Any progress? Is there a discussion somewhere regarding this kernel problem?
Should be all fixed in 2.6.22.1-33, sent to updates-testing this morning but not pushed out to the repo yet.
Thank you. When will it be available for download? Is there a changelog?
You can get an advance copy directly out of the build system here: http://koji.fedoraproject.org/packages/kernel/2.6.22.1/33.fc7/ Changelog is in the package itself, or in cvs.
Thank you again. I have installed it and tested. pilot-link with libusb support seems working perfectly. However there is still an issue with connection Nokia E65 phone over USB. I confirm that it connects and mounts automatically with 2.6.21.1-3228 kernel but fails with any available 2.6.22.1. Is that another bug #249272? Any idea? Any other mass storage devices (USB memory, ATA drives connected with ATA-USB adapter) are mounted automatically. MicroSD from the mentioned above Nokia E65 connected through USB card reader works as well. Only when inserted in the phone and the phone connected over USB data cable in "Data transfer" mode it can not mount automatically. If this is a different bug, I would close this particular one but I think we should wait Robin Gape to test this kernel with PTP camera.
I have installed the 2.6.22.1-33 kernel. USB PTP camera functionality is restored, as far as I can tell. The three test cameras are all recognised, and pictures (images) can be downloaded and deleted. From my viewpoint the bug may be closed. Thanks to Sergui, Chuck and Jarod and whomsoever fixed the kernel bug.
Thank you Robin. I'm closing this bug.
