keyboard driver problem?

[too.much.dudes at gmail.com]

Hello, have problem with A4Tech G7100 wireless combo mouse+keyboard. 
Mouse works fine, but keyboard not. It's loading:
ugen4.2: <A4TECH> at usbus4
ukbd1: <A4TECH USB Device, class 0/0, rev 1.10/1.02, addr 2> on usbus4
but pressing any key doesn't have effect. It works only in one way - if i
pressing one (any) key and don't releasing it and preessing another key at the
same time.

For example to make work key "a" i should press "b" (and don't releasing it,
use like "shift") and after that pressing key "a". And it works.

This problem is only in 8.x branch. At Freebsd 7.3, 7.4 it works ok.
I think the problem is in new ukbd-driver, when i press 'q' key, debug says:

ukbd_intr_callback:547: actlen=8 bytes
ukbd_intr_callback:590: apple_eject=0 apple_fn=0
ukbd_intr_callback:597: [0] = 20
ukbd_put_key:312: 0x14 (20) pressed
ukbd_intr_callback:547: actlen=8 bytes
ukbd_intr_callback:590: apple_eject=0 apple_fn=0
ukbd_put_key:312: 0x414 (1044) released
(this is for usb wire-keyboard that works fine)

ukbd_intr_callback:547: actlen=12 bytes
ukbd_intr_callback:590: apple_eject=0 apple_fn=0
(and this is for my ATech G7100 keyboard)

Could you tell me where the problem is?
