[GTALUG] Stand-alone scanner for Ubuntu?

| So, on further reflection, it looks like the most current 
| Ubuntu spinsare hardwired to always use XHCI. This seems to me to be 
| atransitional problem in upgrading from usb 2.0 to 3.0. If you are able 
| to change this setting with your MB, you might trydisabling XHCI in 
| bios. This should force the system to EHCI and mightresolve what I'm 
| seeing presented as endpoint block errors in bulktransfers. Might also 
| resolve your USB serial issues. Hope this helps.

This sounds crazy.  After all USB 3.0 can do anything USB 2 can do.
But it isn't.

My SnapScan won't work on a USB 3 port with Linux.  But it will work
with a USB 2 port.  Known problem.  Surely a kernel bug but no kernel
hacker has stepped up to fix it.
