I just got the Arduino Uno and the USB host shield up and running, but am getting an error running Oleg Mazurov’s board test when performing the USB test. I get an error code of 0xd (hrJERR - J-state instead of response) back from the MAX 3241 HRSL register. I get this code no matter what USB device I’ve plugged into the host shield.
Does anyone have ideas on what the cause of this is?
