What are scorers using for the OS - Win 98? Me? My XP computers find and
display a USB drive in 5-6 seconds vs 4-5 seconds for an SD card, not
enough time to go that country mile, even with 50 entrants. Does the
problem come from having 50 different USB drives, instead just 5 or 6
different ones?

I also had trouble seeing a significant delay, and I was running
Windows 2000 under VMWare Fusion on a MacBook Pro (so some additional
overhead for device I/O though the virtualization software). There was
no noticeable difference in device detection speeds.
The internal operation of just about every internal SD card reader is
actually a USB interface, same with ExpressCard SD card readers.
PCMCIA is a bit different, but I'm surprised there would be a big
overhead just for USB device discovery. Is something strange going on
with autoplay?
I assume Dave's earlier comment about power consumption of USB to SD
card adapters referred to some of the larger desktop style ones, the
typical small SD to USB small adapters like my SanDisk MicroMate or
SimpleTech Bonzai draw very low currents. I don't have my USB breakout
cable handy or I'd measure the currents but I know it is low.
