He describes that his typing is poor. That pretty much summarizes what I
am seeing on my USB keyboard too - it types poorly. You need to type
slowly and firmly to work - key rollover doesn't seem to work properly.
Also if you hold the key long enough, it will repeat so I get too many
typing errors. I tend to hold my keys down too long (so that Linux's
PS/2 default repeat delay/rate always causes typos - and I rely in the
n-key rollover els I cannot use the keyboard) but I can usually adjust my
keyboarding to compensate (just not comfortable for me yet). However I
just cannot type in my password without seeing what has been typed. Too
many typos!
So, the usb keyboard becomes unuseable for me and I have to hold back to a
PS/2 which works fine (see the way bottom of my message to see what
happens if my password was "the quick brown fox...").
This same keyboard works fine on another computer (HP Visualize C3600) - I
see -none- of the keyboarding problems on that computer (it natively
supports USB keyboards). Also after booting Windows 98, and it loads its
own HID driver, it works fine too - no more keyboarding errors. Before
that time, it has the same problem that I see in BIOS keyboard support.
My Via machine just died last night (again... I hate pc-chips...)
so I no longer have a windows machine to grab info from. My PIIX3
motherboard is still working (knock on wood). The PIIX3 doesn't
initialize USB properly so I can't use USB keyboards in BIOS nor DOS.
(This machine also doesn't have any microsoft OS's on it so I can't check
if the kbd will work in windows. I suspect it will, after drivers are
loaded.)
dmesg, /proc/bus/usb/devices, typing sample (without backspace
corrections which can't be reliably done anyway), and lsmod follows.
Thanks a bunch,

Here's me typing quick brown fox on my usb keyboard (this message was
composed on my ps/2. The following is on my usb keyboard. As you can
see it still gets a good number of characters through, just it loses
some 'scancodes' and starts repeating way too fast for me):
[USB] the quick brown fox jumps over thlazy oog.
[USB] the quick rown foox umps over thelazy dog
[USB]
[USB] the quick brown o jumps over the az dog.
If I hunt and peck and be sure to release my keys before hitting the next:
[USB] the quicbrown x jumss over h lazzy dg
