RE: Ruby on laptops or video over USB

[Yitzhak B. G. <yit...@ya...>]

Ideally, the video controller could be external, like the Japanese did
in the example. The driver requests could be passed over USB to the
external VGA controller and executed there. That is better than sending
an entire video stream over the wire (or even better, wireless).
The advantage of USB is it's multi-channel, so that a future laptop
could host multiple local wireless X stations, which in turn might be
over an extended range physically, like upt to perhaps 30 meters.
Nice, eh?

That driver net2280 already be in the kernel drivers/usb/gadget
Who knows  how about VGA support ?
