--- Comment #16 from Hans Petter Selasky <hselasky@FreeBSD.org> ---
The I/O error is on the control endpoint. I/O error typically means an electric
failure. When devices do not support commands they should return a STALL PID
instead.

There is this knob which you might try setting to 1:
hw.usb.no_cs_fail: 0

Not sure if it helps.
