My Teensy 4.0 boards were working for a while, but now they don't show up on a com port.
I plugged the usb cable into the teensy 4.0
Nothing happened.
Then, I pressed the button on the teensy.
Windows chimed, but I couldn't find any indication in the Device Manager that
anything happened.
I went into the Device Manager and uninstalled all of the Universal Serial Bus controllers,
and then instructed the Device Manager to scan for new hardware.
No matter what I do, the teensy does not seem to be recognized, and
it never instantiates a COM port.
I've tried different Restarting Windows, new USB cables, different ports, but keep having the same results. ...and of course I tried multiple brands and models of boards are recognized instantly.
