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

56 both say "high-speed" which is certainly not USB3.
57
58 At this point, until I can confirm that the USB drive actually behaves
59 as USB3 on some other PC, is it a better bet that the new thumb drive
60 really isn't USB3, or that the motherboard is doing something funne?
61
62 Until I can buy or borrow some device I can truly believe is USB3.0, is
63 there any other troubleshooting I can do?
64
65 Thanks for any suggestions.
