DK91 debugger and USB debugger detection issue, windows 11

[phil38]

I am experiencing an issue with my nRF915DK board. When I connect the board to my PC via USB, the debugger LED blinks continuously.

I have the same issue with a nrf52840DK.

I'm using a JLink_V7.94i driver.

I had try to use different USB cable

The issue has been resolved by removing  all Windows registry entries related to a specific USB device (by serial number), using the following method:

 

1. Download and run USBDeview (free, portable tool).
2. Find your device in the list (look for your serial number: 001051288714).
3. Right-click the entry and select "Uninstall Selected Devices".
4. Unplug and replug your DK.
