Frequently (not always) when I reprogram a teensy 3 (several 3.2s and 3.6s tried) on a Windows 10 computer the Teensy will fail to reappear as a COM port. I can replicate this with the DigitalReadSerial example with USB type "Serial" by doing the following:
1) plug in teensy
2) press compile and upload
3) the teensyloader will show that the code uploaded and the teensy rebooted
4) the COM port will not re-appear (in either the arduino IDE or device manager)
If I attempt to program the teensy again the teensyloader switches to "...manually enter Program Mode". If I press the program button, it will upload and reboot. Sometimes here the COM port will reappear.
It seems like if the COM port appears I can upload and the teensyloader will reboot. If the COM port doesn't appear, the teensy has to be manually rebooted. Un-plugging and re-plugging the teensy does seem to always (as far as I can tell) make the COM port appear.
I tried searching around for this same solution and didn't find anything but please point me towards a post if it already exists.
I'm unsure if this is windows 10 driver related so if there is a way to confirm that the drivers are correct that might be a first step. Is there a list of what drivers I should expect to be using on windows 10?
Thanks in advance for any help!
