So, can you help me understand why a HDMI/USB touch screen would/wouldn't work on any particular Linux running SBC? (Honest question) In my (non-guru) assumptions, both HDMI and USB touch are pretty standard interfaces, and should be abstracted away from any particular SBC. I also assume that HDMI drivers and USB Touch drivers would be common place. Which assumption am I wrong on? Is it a voltage issue? A current supply issue? Something else?
Also, what does the official touch screen use if not USB? Does it then take custom built drivers to function?
