Still not Gentoo specific, but I'm still trying to figure out if my
motherboard (MSI B350 Tomahawk) is doing something funny with the USB
connections. In theory, there should be USB3 connections both on the
back IO panel and on the front case ports. However, everything I have
plugged in to any of these ports, shows up with lsusb -t as on a USB2
hub. However, up to now, I have not had any device which actually
claims to be USB3. I finally ordered a USB3.0 flash drive. When I
plug in into one of the IO panel USB3 ports, dmesg shows:

When I plug it into one of the front ports, dmesg shows:

both say "high-speed" which is certainly not USB3.
At this point, until I can confirm that the USB drive actually behaves
as USB3 on some other PC, is it a better bet that the new thumb drive
really isn't USB3, or that the motherboard is doing something funne?
Until I can buy or borrow some device I can truly believe is USB3.0, is
there any other troubleshooting I can do?
Thanks for any suggestions.
Jack
