I have had this cheap USB endoscope for few years. Then it suddenly stopped working.
So I opened it up to see what is inside and hopefully fix to work again.
The problems seems to be loose green wire. A bit of soldering and it works again.
Not much electronics. Just wiring from USB connector to camera cable and one potentiometer to adjust camera LED light brightness (black wire on cable).
Everything works again. Computer recognizes it as USB 2.0 camera. It also works with Android phone using USBC OTG adapter and CameraFi app.

I had tried several USB camera programs this did not work.
But “USB Camera” application by “ShenYao China” finally worked by fixing the camera connection problem.

Ive found information for every other schematic but the one that I need. Would you please advise me on which wire color to reattach to which point? This model has traditional 4 wire usb soldered at one end of the potentiometer, and 6 wires on opposite end for the camera (where I found 3 had broken away from contact) if looking at it from the back with the adjustable wheel positioned on the left side then from left to right the usb is soldered across the top at Black,Green,White,Red. Looking directly down from that and soldered from right to left is Red, White, Green, then 3 detached of Black, Yellow, Blue. I just dont want to risk putting those 3 to wrong position
