So out of 4 blue pills, 2 of them, which were working ok, are now giving the above error . I was configuring buttons and might also have changed the VID and PID, at the time.

They have R10 marked as 152 (so all good there). I've tried flashing them to JoystickMouse and they connect fine with that loaded - leading me to believe it must be related to freejoy. I've re-flashed. I've changed USB cables and USB ports. I'm running the latest release of FreeJoy.

What is super weird, is that if I leave the ST-LINK USB device connected to the pins on the end of the board (but without the USB end of the ST-LINK connected) , it WORKS! but only for a few seconds. Then it will connect and reconnect randomly and eventually stop connecting.

Have you ever measured the resistors? Unfortunately, you cannot always rely on component markings.

Please also try to erase the flash completely. This has brought one of my boards to life.
