Just a small observation. My USB2 Canon Canoscan scanner does not work
when connected to a USB3 port. Apparently regardless of OS (I don't have
Windows to test but saw posts saying it didn't work there, either).
Someone mentioned that there was a difference between USB2 and USB3 when
it came to handling USB resets or something like that.

I still have a desktop machine here with USB2, so can still use my scanner.

Regardless of that, the KA6 makes me wish I had the money for it!
