yes, you must either hand copy the Oops or run the syslog to a serial
port and capture it there (I've only heard this is possible). After that
process it with ksymoops, otherwise the Oops info is rather useless.
It may be caused by the driver or the USB subsys, the symbolic call
stack may help in searching the cause.

You may give uhci.o a try, if possible.
