Hi,
I’m having an issue with my Teensy 4.1 (Headers).
When I connect the board to my PC via USB, it’s not recognized at all. There’s no sign of power, no LED turns on, and the computer doesn’t detect the device.
Also, after leaving it connected for a short time, the chip becomes extremely hot.
I checked with a multimeter and measured the following:
- 3.3V pin shows about 270 ohms
- Other pins measure between 2.1MΩ and 2.6MΩ
I’ve already tried using multiple USB data cables and different USB ports on different computers, but the result is the same.
Can you please help me troubleshoot this? Or should I consider this a defective unit?
Thanks in advance for your support.
