I just tried, and everything works flawlessly here [2.4.6pre5].
In case you see strange things for some keys but not for others,
try finding out what the keycodes are (say, with showkey).

To: Linux Kernel
I encountered a rather weird problem last night. I was testing out a
USB Type 6 Unix layout keyboard from Sun Microsystems and a USB Crossbow
model mouse from Sun as well. I like the Sun keyboard and mice and am
used to the layout from using it so often at work. I originally thought
that it would be no big deal since they both work perfectly in Windows
(tested while at work on my Windows 2000 box). When I got them home and
tried them out I noticed one thing immediately that I could easily get
the mouse to work with GPM and also I could unplug it and plug it back
in with no problem as all. The keyboard was a different story, if I
plug the keyboard in during operation everything freaks out and I have
to reboot the machine to get it to work properly. I also noticed that X
would not work properly if I had either the USB keyboard and a PS/2
keyboard plugged in or if I had the USB keyboard plugged in alone. No
matter what I tried I could not get X to work, but while trying I
noticed my real problem with the keyboard. The kernel apparently
expects a PS/2 (AT) keyboard to be plugged in because if there isn't one
the kernel reports timeouts and seems slower than when there is a PS/2
keyboard present, my guess is because it is waiting on all of those
timeouts. The next major keyboard thing I noticed is that I can type on
certain keys but if I do anything like hit the caps lock key or number
lock a couple of times then the keyboard stops responding completely and
the kernel tells me that there was an error waiting on a IRQ on CPU #1.
So I guess my questions are the following, is it totally hopeless to
want to try and get a USB keyboard to work as the systems only keyboard
and have it work under X and also not freeze the whole system when
hitting certain keys? Do I just need to give up for now and get one of
those USB->PS/2 converters and use my normal keyboard port, if so will
Linux ever be able to not depend on PS/2 hardware for keyboards on
ix86? I am not looking for anything fancy here, I mean all the extra
keys on it like front, stop etc. would be nice to use eventually but if
they do absolutely nothing that is fine with me, I just want to be able
to use this keyboard. Below are the pertinent .config sections, this is
on a Tyan Tiger 230 which uses a Via chipset. The mouse is still
working right now and X works if I have a PS/2 keyboard only plugged in
and just use the mouse.
Thanks for any help you can give me.

I use a USB keyboard (Macally iKey) and mouse (Logitech iFeel) without
problems. I also get these messages, but I dont see any performance problem.
It may help you to enable an option like "Legacy USB keyboard support" in
your BIOS. This will emulate a PS/2 keyboard until USB is initialized.

This was discussed in the USB mailing list a few weeks ago. Several people
experienced this problem, including me. As a workaround, use the alternate
UHCI (JE) driver.

Yes, the JE driver did solve my problems, the keyboard now works on the
console and under X, and of course the mouse still works. Thank you for
the help.

You are using an SMP kernel. In my experience, nothing USB works with an SMP
kernel >2.4.3.

hei,
I got a compiler source and would like to port it to linux platform later, what
Linux specific directories/ methods I would need for this porting? Any
documemtation available?
thanks a lot

Hm, that's a pretty vague statement :)
I'm happily running USB on a few SMP machines around here. What are the
problems that you are having?
thanks,

Well, the problems I have (had; I'll get to that) are:
* Hard lockup whenever you try to access an USB audio device
* Sudden reboot sometimes when streaming video from an USB webcam.
The first problem appeared in 2.4.3 and only on SMP, but I know work around
that by using the alternate UHCI driver which seems to work well so far. The
second problem persists, but that is probably just a bug in the camera
driver. Nevertheless, all USB devices I tried on { SMP, kernel >2.4.3,
non-alternate UHCI driver } failed, so my statement was correct. :)
Since the alternate UHCI driver works I am satisified, but perhaps someone
interested in the normal driver should look into what happened between 2.4.3
and 2.4.4.
