I got a cheap endoscope USB camera for a PC and Android. I can not make the camera work on Android.
The camera works fine on W10 and Linux, but not Android 5 or 6 (Acer Iconia tablet, with A 5.0.1, and RCA Voyager 3, with A 6.0.1.
I tried programs "USB Camera" as given by the note with the camera, also "Scopecam" as suggested on the net.
I downloaded the apk packages, and installed them.
The tablets see the USB camera but the image returned is black.
On W10 I needed to adjust the "camera privacy status". Is there anything similar on Android 5 and/or 6?
The tablets are off the net and also support OTG.
