Trying to get any comms going with thumbo card with overo tide. By default configuration it will enumerate to my PC as device with pid and vid both set to zero and ends up an unknown device. If I power the board by VBATT and connect to a usb hub none of the devices I attach enumerate. So it seems to be in neither USB host or device mode? Has anyone gotten thumbo usb to work in any configuration? 

Thanks,
Jack
