Non-working touchscreen - USB Diagnostics tool?
I yesterday installed an Opus in my car PC (woo yay works great!), but at the same time my touchscreen appears to have stopped working. I suspect it's the panel (or rather the flimsy FFC to the panel) though I can't see any damage, the PC does see and recognize the USB controller.
I ordered the panel from US and I want to be sure whether it's the controller or panel that's knacked before sorting any replacement. I know there are diag. tools for serial touchscreen controllers, but can I get similar for USB? Or any other ways of testing what's broken? Don't really want to have to replace both!
