Same problem here, I remounted an external USB2.0 drive and noticed it was deathly slow... Checked the "Drive" tab, saw 12Mbps (USB1.1)...
I tried the workaround in the bug description... got up to this step:
7) sudo modprobe ehci_hcd
Then immediately after issuing this command, my computer froze... after waiting a while, I hard-resetting it
Reconnected the drive after it booted, and I had 480Mbps!
Not sure if there is a safer way to reset the speed?
