I'm working with Teensy 4.1 on up to date Windows 10 with Teensyduino 1.56, and I can't get the system to recognize the USB serial device.
With a brand-new Teensy, it shows up in my system as a raw HID device, as expected:
If I then upload the blink sketch with "Serial" selected as USB type, the upload goes fine but the port shows up as [no_device] and there is an error message in the device manager. Trying to reinstall the driver in device manager fails to find a driver, and trying to install a driver from the Teensyduino installer comes up with "Windows 10 USB serial driver found. No driver installation needed."
If I try to upload code from this state, the Auto function on the loader fails and I have to press the button to enter programming mode.
I've experimented with the "Serial + (other)" with similar results.
If I set the USB Type back to "raw HID" Auto upload works correctly again.
I've tried two different Teensy boards and built-in and hub USB ports and gotten the same result.
I use a USB to RS-485 adapter on this system and it works as expected, though it is not currently connected.
This seems to be a Windows issue, does anyone have suggestions for getting the Teensy serial port to load properly?
