I just bought a Surface Pro, second hand. Tragically, the day after I connected a broken/cheap 3.0 HUB and managed to 'fry' the only USB port. The port isn't able to provide 5V anymore, but the data connection still works.
Too bad the Surface Pro is too hard to open, let alone fix! Now I will have to provide a proper powered USB hub just to connect simple devices.
I wonder if I could draw the 5V power from any other connector around the surface, or even if I open the Surface, if I could make a connection between the USB's VCC pin and any other place in the device (an internal USB connector which drives the SD card reader?). But it seems too risky to open the device, and the external connectors remain a mystery.
I feel very bad, the toy didn't last a day. Any lights?
