Recommended Posts

This code has only been tested in Windows XP running with in a virtualbox on my Linux box.

If other could give me feed back on how it runs on other systems it would be helpful.

Thanks for the helpful tips.

If you read the description in the code, you would see why I put it in the loop.

If you are familiar with the Windows OS you know that it can take it a while for it to detect a new keyboard.

So, My code loops in case is it missed the first time around.

Um, loop loops around as long as the teensy receives power, which in a case where you leave it in the computer for 30 minutes, this code would almost run 1000 times, it doesn't stop at two.

You only need to have it running once, as the code runs AFTER the device is enumerated ie. after the keyboard and mouse will work.
