it was concluded that this should be rather be xhci quirk instead of rt2800usb driver flag.
If change from comment 147 help for you with the problem, please provide PCI-id of your xHCI controller. This can be done by command:
lspci -k -nn | grep -B2 xhci
If you have more than one xHCI controller please assure you provide PCI-id's of one that actually has the problem ('lspci -t' command can be useful as well)
