Some info that I should have included in my previous message...
I've included /proc/bus/usb/devices and /proc/bus/usb/drivers as
attachments.
As you can see, the scanner is recognized just fine, including
high-speed capability when plugged into high-speed ports, so things look
promising. I just need to figure out how to get the read to stop
hanging.
I would really appreciate any hints!
