Weird USB Problem

[pwnawannab]

I am not really sure how it began but during normal operation (meaning machine boots up runs for awhile with no issues) for no good reason USB peripherals suddenly become unresponsive. Running 10.3 with KDE. Fairly certain it is not HW problem. I dual boot with XP, and other OS does not have this problem. USB mouse becomes unresponsive (lights are if mice was not unpluged); Other non-USB peripherals are fine, applications which were in execution are fine; can not switch to another tty (ctl+alt+F#); lsusb hangs with no output; yast is able to gather HW info including USB devices; when killing X11 (ctl+alt+bckspace), I am not returned to either shell prompt or KDE logon screen. I work around this issue at present time by rebooting the system. I am puzzled as to how to troubleshoot. I'll take any suggestions.

Try replacing your USB mouse and USB keyboard with another USB mouse/keyboard that you know works well WITH LINUX. The idea here is to take those devices out of the loop.
