My laptop not recognize Fc

Some one give me drone to repair it when I connect it to laptop it’s not recognized but the Fc is ok and working
I think he disabled msp or USB some how
May he used wireless telemetry or Bluetooth to connect Fc with laptop?
Which telemetry can do that ?

…………….
What FC is it?

I have 2 FCS till now from the same store same issues
Kakute H7 v 1.3
Matek H743

How are you trying to connect and to what? Mission Planner?

USB cable . Laptop not recognize it at all

Un-install MP, reboot and install the latest MP version.

Bro it’s not related to MP at all and I already having last version and reinstalled it as you mentioned
but some how MSP disabled through telemetry .
Am asking how to enable it again

MSP is for INAV or Betaflight, Ardupilot has nothing to do with it.

Press the Boot button, plug in the USB cable and flash Arducopter with whatever application floats your boat.

Bro please please understand me
I have drone already working with arduopilot and seeing that throw Tele button on my radio
It’s so easy to flash new firmware I can do that .
My issue my laptop not recognize the Fc because usb disabled I just need solve for that

Do as Dave suggests and then start the ImpulseRC Driver Fixer. Normally this will fix the DFU connection and activate the correct driver.

Then disconnect and reconnect the USB cable. Then it should work directly.
