Title: Computer doesn't recognize teensy / keyboard when plugged in
Post by: greenwhite on Tue, 14 June 2016, 11:59:21
I completed the construction of my keyboard and compiled a tmk hex file.  When I went to install the hex file on the teensy, the computer doesn't recognize that anything is plugged in.  I'm not sure if this a common problem, but any help would be appreciated.  I'm using a Teensy 2.0, the USB is 3.0, and I'm running Windows 7  if that helps.

You need to update the atmega drivers possibly.

There aren't any special drivers for a Teensy, have you pressed the button on it?  Does the LED flash when you do or is it completely dead?

I pressed the button.  The board is completely dead.  I can feel the chip get warmer when its plugged, so I assume its getting power.

You could try it on a USB2 port but that sounds dead to me :(

I probably fried it with the soldering iron.

Verify that the Teensy isn't a counterfeit:

In case this happens to anyone else, I tried using a USB 2.0 cable instead of 3.0 and now its working.  I haven't seen any posts regarding issues with Teensys on USB 3.0, but for me it was a problem.
