Well... I tried it. No help. My test USB3 FLASH stick is recognized
(at USB2 speeds) on the USB2 interface, but it is not seen at all on the
USB3 interface -- there is nothing at all in the output of "dmesg" at
the time of insertion, and, of course, no device node is created for the
drive.
Any other suggestions, anyone?
Please!
Thanks,
Rick

Good hint…
I came across this

I haven’t tried it yet, but it’s almost the only hope I’ve found so far.
Lots of folks say their USB3 ports work fine under Windoze but fail (in various
ways) under Linux, so it’s not likely to be the hardware at fault (or at least,
if the hardware is broken, MS has a workaround that Linux doesn’t). I don’t
have a working Windows boot disk for this machine, so I can’t check if my
situation is similar.
There are several threads from the Ubuntu forums (I’m using Debian Stretch, but
I’ll take any port in a storm!) indicating that a *lot* of people are
encountering similar problems with USB3.
