Hi,

I have some problem with an USB HID mouse device. It is the mouse
demo for Olimex LPC-P2148 (http://www.olimex.com/dev/lpc-p2148.html),
a popular low cost Philips LPC2148 USB ARM MCU.

In fact, it is also problematic under Windows XP. Often Windows reports
that it is an "unknown" USB device. I have tried to use different USB
cables but the result is the same. I guess there is some problem with
the NForce 3 chipset I am using. But I also suspect that there might
be some firmware bugs. Linux is reporting more meaningful errors.
Any ideas what could be the problem? Thanks in advance.
