So it seems like the teensy functions just fine, I can reset it to blink, I can flash different sketches to it. But it just will not turn on or be detected by the computer until I short the USB connector ground to the USB power.

I don't get any error messages when flashing sketches to it, I've just flashed a modified blink sketch and it seems to work fine. Also, when trying to do the memory wipe and blink restore, it doesn't seem to work. I held the button down for a long time and I just saw one red flash from the red...

Yes, so it was a very cheap hub and I think it fried something in the teensy when it was connected. I am no longer using it and my Teensy is connected directly to a USB port on a computer using a different micro USB wire. I still can only detect the teensy when I do that short quickly.

I have done the Memory Wipe and LED Blink Restore process, it does connect to the computer and I can access it with the Arduino IDE. I have not taken out the fuse. I can't detect the Teensy through USB until after I short the USB power pin to the USB ground pin. Could the USB interface on the...

Hello, I have a Teensy 4.1 that I connected to a USB hub, this caused the Teensy to not be detectable from Arduino IDE or Device Manager. Eventually, I connected the ground of the USB port to one side of the F1 component and there was a slight spark, then the board connected. Is it ok to bypass...
