Hello,
Working on my project, the Teensy *always* requires me to push the button to program it. Here's what it says:
----------- snip -------------------------
Unable to open COM8 for reboot request
Windows Error Info: Access is denied.

Teensy did not respond to a USB-based request to enter program mode.
Please press the PROGRAM MODE BUTTON on your Teensy to upload your sketch.
Unable to open COM8
---------------- endsnip ---------------
Then I push the button, the upload happens, and I continue developing.
------------ snip ---------------------
Now able to open COM8 (Windows said this port was ready before it was actually ready...)Disconnect COM8
------------ endsnip -----------------
I seem to remember reading that this is so because the USB port is not paying attention. What exactly do I need to do in my code to make it pay proper attention? The serial monitor *does* work.
The button is a big deal because the Teensy is mounted upside down, and the button is between
the two circuit boards. I am able to push it with a toothpick marked to show exactly how far in to stick it. The button will be an even bigger deal once the Teensy goes into the equipment cabinet.
I suppose I *could* rig up some sort of little bellcrank with some string .
