Maybe I expressed myself badly. What I wanted to ask is if it is possible to power the device and output video at the same time using one of the usb ports. I don't intend to draw power from the device but to give power to the device (and output video).

Can support mesa GPU driver, compatible with X11 WAYLAND Currently maximum 128 G, more than 128 G need to be customized, such as 256 G.

@jack_admin thanks!
