that doesn't compute.    USB 3 uses a different (new) set of 5 pins on 
the same connector, but the original 4 pins are still there and support 
USB 1 and 2.    A more likely explanation is that the device driver for 
this printer isn't enumerating USB devices correctly, or isn't handling 
some additional usb3 related port-specific status information correctly, 
so its getting confused.

The whole USB spec is a ungawdly mess now with layers and layers of BS 
piled up on a shakey foundation, and complicated APIs to access all this.
