19 You can find udev's action rules under /etc/udev/ ... Maybe you'll
20 find what you need there.
22 Note that most motherboards don't make every port USB3. In fact, I
23 haven't yet seen one yet that does. If you look next to the port, you
24 may see the text 'USB3'...try plugging your dongle into a different
25 port from that one.
27 The other thing you might do is disable USB3 in your kernel
28 configuration or BIOS. (Enable UHCI and EHCI, disable XHCI). Make sure
29 you have a PS/2 keyboard on hand, just in case.
31 On the other hand, it could just be that your dongle doesn't work;
32 that error sounds suspiciously like a misbehaving USB device. Try it
33 in a different system.
