USB problems with 2.6.11-1.1258_FC4

[Edwin Olson]

Upon updating to the new kernel (1282 on x86), USBstopped working. lspci 
still showed the usb adapters (but maybe only the USB 2.0 ones?), but 
lsusb showed no devices (including my mouse.) The devices did not appear 
to get enumerated-- the LED on my mouse never turned on.

This is a FC4T2 machine, a dell 8250 P4.

I saw nothing relevant in /var/log/messages. I had no trouble with 
previous versions of fc4t2 kernels.
