I have a teensy 2.0 connected to a stepper motor shield and motor. While debuging some software I got a driver update notice which I clicked to install. Now, when I connect the Teensy to my laptop or my desktop computer, the Device Manager shows it as Portable Device, E:\ instead of an entry in PORTS and COM, and I get an AutoPlay window for Removable Disk (E:). When I click the 'Open folder to view files' button it lists a Readme.txt file. The contents of that readme are:
"This USB disk was automatically formatted when you compiled your sketch.
You can place files to be copied onto this disk, instead of this Readme
file, in a "disk" subdirectory inside your sketch. That location
would be:
C:\Users\Weber\Documents\Arduino\IRteensey\disk
For a blank disk, just create that directory but don't put any files
into it. To name your disk, create a file ".VolumeLabel" with the name."
Apparently the driver I allowed to download has overwritten the USB/Serial software in the Teensy. What program is loaded in the Teensy's ATmega32U4 that provides the serial interface to the USB? HalfKay? Can I install it? What do I need to do it?

Re: Teensy 2.0 serial interface problem
Wow! Never heard of anything like that. Nevertheless, it sounds like it should be reversible. If you contact PJRC, they should be able to provide information on how to re-flash the firmware on the Teensy. (And maybe offer some insight about how it happened in the first place)

I finally got a reply from Paul to try the recovery procedures in http://www.pjrc.com/teensy/troubleshoot.html.
Worked. I can now program my Teensy.
