Sorry. Dmesg error was the same -22, that is why i did not send dmesg
output.
I tried as you told, to disconnect all USB devices, including mouse and
connect only this keyboard. I did it on 2 notebooks, one is Maxdata
O.book, another is Toshiba Satellite. O.book has some built-in USB
devices which I can not disconnect, Satellite has no built-in USB
devices. I also mounted debugfs and redirected output from 0u socket
into file.
You can find lsusb -v, usbmon and dmesg output for both notebooks in
attachment.
Everything was done on Debian Squeeze, kernel 2.6.32. I have here also
Livecd with Suse 12.1 with kernel 3.1, so I can repeat this with this
kernel if needed.
