Since I bought a new BTC keyboard kernel starts to wait for uvents to be processed for about a 10 secs.
Here some relevant strings from dmesg:
Code:
...
...
[    3.589048] NVRM: corruption and stability problems, and is not supported.
[   11.588903] hid-generic 0003:046E:6000.0003: usb_submit_urb(ctrl) failed: -1

Code:
Bus 001 Device 004: ID 046e:6000 Behavior Tech. Computer Corp.


I've looked around - there are some tips for such a behaviour, e.g.
Code:
echo "options usbhid quirks=0x046e:0x6000:0x20000000:" > /etc/modprobe.d/usbhid.conf

but it doesn't help, possibly due to incorrect parameters for quirks.
Where can I get correct parameters for my keyboard?
Or may be it should be solved in some other way?

Solved:
quirks should be added to kernel command line instead of usbhid.conf because usbhid built in kernel, not as separate module:
Code:
usbhid.quirks=0x046e:0x6000:0x20000000
