Can someone help me?
I have a purple CWWK board, and can't figure out how to make USB 3 speed work on any USB port.
Connecting a USB 3 external hard disk to one of the front panel ports, or the port labeled "USB3.2" on the manual on the back panel works, but only at USB 2 speed. Other ports do not work with my USB 3 external hard disk at all.
A prior commenter seemed to have success by changing some BIOS setting to "Auto". (see comment #661 by
@mrvladis)
I tried changing "Legacy USB Support" in BIOS to both "Auto" and "Disabled", but could not get USB 3 speed working.
Is there some other setting?
In case it's related, there are error messages in dmesg on boot:
Code:

Can someone point me in the right direction?
