Titan Mobile External DC Supply

Postby watty » 11 Nov 2019, 19:04

I have put my Titan Mobile into a flightcase and supply it with 9v DC from a separate PSU via the integral DC input jack to reduce the load on my laptop USB supply. I have just found when using a USB hub between the laptop and my Titan Mobile that the hub is being powered by the external DC from the DC input socket travelling back out of the USB port into the hub. This must mean that the external supply input of the Mobile (after being reduced to 5v) is outputting from the Mobile USB port and being applied to the laptop USB supply by the connecting USB cable. Surely this is wrong and the external supply should be isolated from the USB socket??? The USB hub lights up as though powered even without being connected to anything but the Titan Mobile.
