full dmesg output

Hi,
Originally I posted this problem at gentoo bugtrack, but their kernel team redirected my issue here. So the problem is with a Gigabyte K8100 keyboard. Its behavior is simple: it doesn't send any keycodes to applications, but integrated in keyboard USB hub works. Why I thinking that its kernel related problem? Well, I tested this keyboard with 4 machines running 4 different Linux distributions (Gentoo, Ubuntu, Archlinux, Centos), having same result and same suspicious error-part in dmesg (while it nicely works in MS Windows and on BIOS POST screen):

also I can see a bunch of new devices by lsusb:

  9 Bus 001 Device 003: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
...
 13 Bus 001 Device 004: ID 1044:7a02 Chu Yuen Enterprise Co., Ltd
 14 Bus 001 Device 005: ID 060b:2270 Solid Year

Steps to Reproduce:
1. Connect a Gigabyte K8100 keyboard
2. Boot up any Linux-based distribution
3. Enjoy

Note:
In fact not all keys aren't working -- the volume control is the only thing that works.

Actual Results:  
Keyboard practically not working

Expected Results:  
Keyboard nicely working
