Hello,
I have a program running on Teensy 3.5 that communicates via serial protocol over USB. This has been working and I have updated and reprogrammed the teensy several times. The program on the PC now doesn't connect to the Teensy.
When plugging it in I get the windows sound for a new device found but there is nothing in device manager, specifically for com ports.
If I try to reprogram the teensy I get a message: "Teensy boards were found on any USB ports of your computer."
Also, there is no port listed under tools -> port.
I press program button but makes no difference. I have looked at the verbose output from the teensy loader. When I plug into USB port I get this:

I have followed that troubleshooting guide for Teensy not recognized for Teensy loader. ( https://www.pjrc.com/teensy/troubleshoot.html)
I tried loading a simple blink program. Using debug procedure I press program button, plug in teensy and then release I get this.

I looks like it was programmed and the sometimes that LED will flash a few times before going out.
I am running on Windows 10, with Arduino IDE 1.8.7 and teensy loader 1.44 . I have also tried on a Mac with the same results.
I have had two Teensy 3.5 that have had the same behavior. They worked fine for multiple days, programming and communicating with my PC application and then stopped working and then were not able to be programmed or serial communication.
Any suggestions?
I have a program running on Teensy 3.5 that communicates via serial protocol over USB. This has been working and I have updated and reprogrammed the teensy several times. The program on the PC now doesn't connect to the Teensy.
When plugging it in I get the windows sound for a new device found but there is nothing in device manager, specifically for com ports.

Also, there is no port listed under tools -> port.
I press program button but makes no difference. I have looked at the verbose output from the teensy loader. When I plug into USB port I get this:

I looks like it was programmed and the sometimes that LED will flash a few times before going out.
I am running on Windows 10, with Arduino IDE 1.8.7 and teensy loader 1.44 . I have also tried on a Mac with the same results.
I have had two Teensy 3.5 that have had the same behavior. They worked fine for multiple days, programming and communicating with my PC application and then stopped working and then were not able to be programmed or serial communication.
Any suggestions?
