I have done a fresh install of the Arduino 1.8.10 IDE, followed by an install of the TeensyduinoInstall.exe 1.48.
I am using a basic sketch that compiles with no issues.
Arduino menu:
Board is set to 'Teensy 4.0'
USB Type is set to 'Serial' (There are no other options present)
Port is set to 'COM1' (There are no other options present)
After plugging in the Teensy4, I have a running Teensy with a Blinking Orange LED (the default application).
If I attempt to use the Arduino IDE to Compile/Upload the simple Sketch, the Teensy Loader opens as expected, the code compiles successfully, then I see in the IDE:
"No Teensy boards were found on any USB ports of your computer."
"Please press the PROGRAM MODE BUTTON on your Teensy to upload your sketch."
....at which point I press the Program Mode Button on the Teensy. The orange LED turns off, and the red program LED illuminates. Then then nothing happens. No more feedback from the IDE, no change in the LEDS.
I know that the USB cable is good because I have been using it to program other Arduino-type devices. I have tried several different USB 3 and 2 ports, with and without a USB Hub.
I have attempted going through the Troubleshooting section of the Teensy web pages but can't seem to get past this error.
I have also tried "holding the reset button down while plugging in the Teensy to the PC, then letting go of the reset button" all while the TeensyLoader is running. No change in behavior (RED Led stays lit).
I have checked through the Windows OS' Device Manager/Human Interface Devices list, and can find no indication of an HID-Compliant Device matching the Teensy/Halfkay identification information. Nor does an HID-Compliant Device entry appear/disappear when I connect/disconnect the Teensy4 USB connection.
Would someone provide a suggestion on how to proceed?
