Hi,
I have tried connecting to the USB 2.0 connectors on the main PCB but the device is not recognised, is there anything that has to be done to enable these?. The wires going onto the USB cable from the connector are short, so its not likely to be an impedance mismatch and the 5.0 volts is also present. Also is it possible to force the ports to USB 2.0 in Ubuntu by forcing the device to use xhci_hcd?, I need this to get isochronous audio working. Thanks in advance!
