Update (August 2016)

Please take a look at these updated instructions on Github to troubleshoot issues you have with Windows and Tessel 2.

Older instructions (pre-August 2016)

A holdover fix for Tessel 2 drivers on Windows:

1. Download and unzip the archive on this gist, t2-windows-fix.zip

2. Open a Command Prompt in the newly unzipped folder using Run as administrator.

3. Unplug Tessel 2 from your computer.

4. Run node driver-clean.js.

5. Hold down the reset button near the edge of Tessel 2 (by the antennas). Plug in Tessel 2. It will now be in DFU mode.

6. Run node driver-install.js.

7. Tessel will reboot and working Windows drivers will be loaded. In about 30s, run t2 list to see if this was successful.

Having run the above steps, your computer will have uninstalled the old Tessel 2 drivers. Tessel 2 is now flashed with firmware that works on Windows out of the box.

NOTE: A Tessel 2 with updated firmware can use t2 update as normal. You do not need to repeat the above steps on a new computer that has not been exposed to the old firmware.

I had the same problem as @shanselman but got it working after installing the driver using Zadig in DFU mode.

This process worked for me until I unplugged the Tessel 2; then when I plugged it back in a few days later, t2 list produced:

INFO Searching for nearby Tessels...
WARN Detected a Tessel that may be booting.

I repeated the same procedure as before, but no luck and I am back to square 1 on Windows 10 x64

Hi. Same problem. Windows 10 x64, Node v4.3.1.

Running the gist failed as @shanselman and @wmmihaa.
Adding the WinUSB driver for Tessel from DFU mode with Zadig helped (Thanks @wmmihaa!)

However, then I got the following error running t2 list:

Fortunately, all I needed to do was to create that .tessel directory.

C:\Users\Joe\Documents\Software\Tessel>t2 list

Then it worked.

@rlramirez, are you waiting for the blue LED to stabilize? It's about a 30s boot.
