While I can be a cheapskate, making the problem go away is worth
spending a few bucks.  Know of any sites that list USB controller
cards _and_ the chipsets they use?

By the way, I had measured throughput to the USB drive and found
I could transfer a 1GB file from internal HD to the USB in 57.9
seconds, which translates to 18.5 MB/sec.  Would that be
considered a good or bad USB 2.0 transfer rate?

Thanks.
