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. [EMAIL PROTECTED]:~$ uname -a Linux ubuntu 2.6.15.5 #1 Sat Mar 4 13:20:36 SGT 2006 i686 GNU/Linux [EMAIL PROTECTED]:~$ dmesg ...
