I just got a USB keyboard for use with my ThinkPad A30. When I
plugged it in the first time, it worked great. Then I unplugged it
for the night. But the nefxt day when I plugged in the keyboard
again, the kernel broke.
Quoting dmesg:
usb 2-2: new full speed USB device using address 5
usb 2-2: control timeout on ep0out
After that timeout, the USB subsystem seems totally stuck. Nothing I
do provokes any further response.
In an attempt to work around the problem I build the USB code as
modules; but all I got for my trouble was a hung "rmmod uhci_hcd".
