Re: USB kernel oops
More information: Today I was still using it and noticed that I actually had another USB keyboard attached. (Since this is a wonky dell whose bios doesn't work with the Kinesis USB keyboard I had a generic USB keyboard plugged in also.) That keyboard was unresponsive. Very soon after attempting to use that keyboard, my Kinesis USB keyboard also stopped responding.
