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.
