Are you using a mains powered usb hub or just directly from the usb power ?

I would add a power supply to the Arduino or a powered hub

When you use an unpowered usb hub, the hub can only provide a max of 500mA coming from the PC usb port, to be distributed among all the usb ports in the hub. That might be ok if you don't have many output devices, but you can quickly run out of power, as you plug more devices.

So, I highly recommend that you only use powered hubs with Mobiflight.

In some instances, where you have large power consumers like a large backlighting group of LEDs, many 7 segment displays, or servos and stepper motors, you will need to supply additional power from an external power supply.
