Bugzilla Bug 175715

Sorry for my bad english,
I have upgraded 2.6.19-r5 to 2.6.20-r6 and udev (i think) don't create my usb
micro device anymore....if I come back to 2.6.19-r5 then it's all right..the
micro usb is created..
I have upgraded with make menu config (not with make oldconfig) and I have no
answer on forum
The camera is ok but not the micro
Nothing interresting in my logs
I have the same issue with the new ubuntu (kernel 2.6.17 ==> 2.6.20...)
that's why I think there is a problem with the new stable kernel...

Can you reproduce this problem on the latest development kernel, currently
2.6.21-rc7?

unfortunaly yes...I've tested with 2.6.20.7 and 2.6.21-rc7 and I've got the
same problem.
For the moment I keep 2.6.19-r5 in order to use my quickcam messenger's micro

Please attach dmesg from an affected kernel, where the usb device has been
plugged in. Also post /proc/bus/usb/devices from a bad kernel and a good kernel
(both times while the device is plugged in).

dmesg and /proc/bus/usb/devices from both kernel

Hi and thank you very much for your help,
As you can see  /proc/bus/usb/devices shows that the camera has no audio driver
..."01(audio) Sub=01 Prot=00 Driver=(none)"   but snd_usb_audio is loaded 

Please attach your 2.6.20 kernel .config and show the output of "uname -a"
while running the affected 2.6.20 kernel.

I've just tested successfully this patch created by sergio martinez on the
ubuntu's bug report. It works!
My micro is ok now
Do I have to close this bug ? 

Thanks for the info. Don't close it yet - give us a chance to review the patch,
ensure it gets accepted upstream, then backported into a gentoo release.

Sent a patch upstream
