You can get a signed version of the USBasp driver from http://www.protostack.com/accessories/us...
Should make things a lot easier.
Correction: the batch file for all newer firmware versions is "flash.bat"
The firmware link in the store just points us to the GitHub repo. Where can I find the pre-compiled versions of the firmware?
Pre-Compiled versions are located at:
OpenEVSE Github

The USBasp that I got had a ribbon cable. Orientation of the cable is tricky - The key on the cable jams into a part on the OpenEVSE board. I had to shave off the key to get things to work. Once I did that, things work great. Even from iOS, writing with the Arduino software.
