My USB microscope stoped working

I have USB microscope and this is the hardware number: USB\VID_05E3&PID_0510&REV_0509&MI_00

And the PC recognize it as Lenovo easy camera. And it's true.

My OS: windows 10

What I have tried:

• Uninstall all drivers and install them again.
• Uninstall USB hubs and install them again.
• Connect the Microscope to other PC and it works!
• Update windows 10 and drivers.
• Connect it to different USB port.
• Remove all USB devices and just connect the microscope.
• I have tried different apps with it, the same thing "black screen"
• also I have restarted the PC several times.
• Also removed the USB cable and solder new one to be sure not from the wire.
• There is no errors at all in device maneger.

I usually use the built in camera app that came with windows 10 to show the microscope.

I was using the microscope, then sadenly black screen, all apps detect the microscope, but it's just black screen, no image, I thought the microscope have a problem, but It's works on other PC.

I just found this in the event of the device

I found the problem!

If anybody have this issues with a microscope or any kind of camera, it because OBS program set the frame-rate out of range the camera, the only way to make it work is to Uninstall OBS program, or any program that can change the frame-rate of the camera.

for allowing windows 10 connecting your camera or microscope usb to ur software

1-please go to start (press windows key)

2-type camera privacy setting

3-get access of camera to the program (****ON** the access** of program)

hope you enjoy it

I encountered the same situation recently.

Connect device to "USB Camera" app in Android and adjust "Power Line Frequency" setting from Disabled to Auto (or 50/60 Hz) will restore image. Looks like Windows 10 changes this setting.
