My pico w was running fine until I assigned the script below as main.py. Running Windows 11.
Issue: Board is no longer recognised by Thonny, and it is showing in Device Manager as an unrecognised USB device. Disabling it and uninstalling it doesn't change anything. Pressing and holding the bootsel button doesn't make anything appear in explorer. Trying to manually install drivers via device manager also doesn't work. Thonny shows 'Unable to connect to com4: port not found. Process ended with exit code 1'. If I go into Run=>configure interpreter and try to reinstall the firmware, nothing available appears (regardless of bootsel button being pressed before connecting to usb). I tried installing libusb-win32 and also winusb (libusb) via zadig with no joy (zadig said 'installation failed'). Tried changing laptop; same symptoms. Same for changing usb cable. My other pi pico w works absolutely fine.
Interestingly, the script itself seems to be running perfectly on the board. I can use my phone as an access point to remotely control the onboard LED. So perhaps main.py is preventing the USB dependent scripts from running somehow?
Anyhow, could the script below have somehow damaged the USB? Could there be a hardware fault somehow? Is there any way I can prevent this in the future? Apologies, I'm a dev newbie so any advice is appreciated - thanks.
