In my current setup the board is drawing about 850 mA with the backlight off. +I've been using this hub: http://www.adafruit.com/products/961 I've also run the board without a hub (and the PC was limiting the current to 500 mA), which means that something was suffering for not having as much current. + ###Entering DFU mode### The board doesn't provide a convenient way to enter DFU mode. There are several techniques that can be used to enter DFU mode. DFU mode is available on the USB FS connector (CN13)
