Re: Alpha disabled usb from bios

The USB header does work for me.

BIOS setting to disable USB power

It would be great to only turn on the USB power when the LattePanda Alpha is actually 'Powered On' (OS boot) not when it receives external power.

PyMata examples

Examples of using the PyMata library would be good.

SPST switch for power on / off

How to add a SPST switch to power on / off the LattePanda
When switched off, gracefully shutdown Windows / Linux.
