Wouldnt that show up on all usb ports and not just one(set)?
My /home is on a different drive - thankfully.
My os is on a brand new drive - not that that means anything :D
Running lsusb I show 8 usb ports.
I have actually six.
Shuttle specs say I have two front and two rear 2.0 ports and two 1.1 ports.
However, when I plug into all of the six ports, none of them are 2.0 usb ports.
It might be the motherboard.
