One more thing: with these types of events, Event Viewer will usually
note errors referencing something like usbscan.sys.
You seem to have an good understanding of PC's but,I'd check the basics
first (after verifying the Scanner's Display upon dropping off the bus)
1. In device manager, change the view to resources by connection and
check your PCI USB Address. Make sure it's not sharing with something
like your video, NIC, etc... If it's sharing with several high-refresh
rate devices, then find another USB port (on-board if possible and on
it's own controller) remember each controller is connected to an
internal hub- you don't want to put a highspeed scanner on one port and
connect something like a printer in the port directly next to it since
it's most likely sharing the same USB controller internally. )
Unfortunately, the motherboard only has USB 1.1, which is why I put in
the StarTech USB 2.0 card. Here is the printout from Device Manager:

2. if the problem occurs again, try leaving the scanner on (only if you
don't see a flashing E in the display) and scan for hardware changes
via device manager instead.
I'll try that. Hopefully I can get it to fail again on this batch.
Thanks.
