Hi,
I'm running FC4 on a laptop been experiencing usb problems since the last
round of FC4 updates. Basically the symptoms are that if I plug in my usb
mouse, which has worked find up to this point, the system goes into a cycle
of 100% cpu usage for a few seconds, which then stops for a period and then
restarts. The mouse does not work (It might for a few seconds but then
stops). Thankfully the touchpad works OK...
Does anyone else have this problem ? Any suggestions what to do would be
greatfully received as this is rather annoying.
I've just checked my system log, and found the following which I guess is the
problem.

OK, so what should I do to fix this.
Many thanks in advance.
