Hello everyone,
I know you have answered these questions before. But I guess my problem is a little different than others. I have Teensy 4.0. When I first plugged the Teensy to the computer, I did not encounter any problems and I did my programming with the Arduino IDE for a long time.
I touched the Teensy today with the Teensy plugged into the computer and powered on. Then Teensy really started babbling. When trying to communicate via COM port, sometimes the serial monitor worked, sometimes it didn't. In the last case, the COM port has become completely inoperable.
After this problem, I took a multimeter and made measurements. The 3.3V and 5V outputs work smoothly.
After doing research, I thought it might be related to cables and tested it with 3 cables. I had the same problem on all of them and I couldn't get Teensy to work. However, the first cable I tried was able to transfer data and electricity very well.
Currently, the red light on the Teensy is flashing at regular intervals. If I leave it like that for a long time, that light goes out completely. But it still doesn't read COM port. Regarding this I tried pressing the reset button for 15 seconds. I also pressed it once. It did not respond to the reset in any way either.
I wanted to summarize the situation better by making a video. Below you can find the video explaining the situation. I really need your help. Thank you for your interest.
