        Interesting.. it detects it, as per dmesg below, but then it frees 
it.. really interesting..

        I've tried this with 3 different keyboards, 3 different mice, and 3 
combinations of each: wireless 104-key ps/2 keyboard. PS/2 cord from the box 
to the keyboard base, actual keyboard is wireless. bought it 4 years ago; 
104-key keybord (w/power, sleep, and wake keys) bought 3 weeks ago, 104-key 
acer keyboard from a P100 from 7 years ago. all 3 mice are PS/2 mice; Acer 
mouse to go along with the Acer box and Acer keyboard, Microsoft PS/2 mouse, 
and MS Optical wheel mouse. The Acer and MS PS/2 mouse are straight PS/2. The 
optical is IMPS/2. motherboard is a Tyan S2390B, VIA82c686b chipset. 

        All 9 different combinations gave the same result. Mouse working, 
keyboard not working.

                                                        BL.
