usbmon traffic

Hello,
after upgrading to kernel 2.6.28-30 the multimedia keys on logitech s510 keyboard stop working.
There are no events on those keys when trying xev but usbmon is collecting some traffic.
In kernel 2.6.26 at least some of multimedia keys have been working (cannot confirm in 2.6.27 but I can try if needed).


Keys in order collected in attachment: run player, play/pause, stop, forward, backward, shuffle, volume up, volume down, mute, zoom 100%, zoom out, zoom in, rotate, home, sleep

Could you please verify with 2.6.30?
Comment 2 Tomas Potocky 2009-06-17 20:03:46 UTC 
OK, I've done more testing with different kernel versions and now I see what is the problem. I was using 686 kernel until 2.6.26 and then switched to amd64. (debian packaged kernels)
So I can confirm it's working with 2.6.30-1-686 but not with 2.6.30-1-amd64.                               
Could it be a missing module problem? 
I'm attaching lsmod listing for both kernels.

Comment 5 Dmitry Torokhov 2009-09-05 06:43:00 UTC 
Do the keys generate events when you run evtest utility using the event device corresponding to the keyboard?
Comment 6 Tomas Potocky 2009-09-05 08:24:36 UTC 
No, the keys do not generate any events using evtest utility. 
I'm using latest kernel 2.6.31-rc6-amd64
Comment 7 Tomas Potocky 2009-09-21 19:17:03 UTC 
I stand corrected, evtest is generating events, on other device though.
cat /proc/bus/input/devices 

Standard keys:

I: Bus=0003 Vendor=046d Product=c517 Version=0110

So I assume it's not a kernel related and you can close this bug.

Yes, quite often we find with USB that a physical device is "split" into 2 or more logical devices.
