Leopard board is configured as USB device mode by default.

With current version of Leopard board (1.0), there is no jumper to set it to host mode.

A quick and dirty fix is to wire USB_ID to ground (schematic page 5), and connect 5V power to USB_VBUS.

Then the Leopard board is forced to host mode.


Jumpers will be added in next version to switch to both host mode and device mode easily.
