USBASP Programmer for AVR is working on Windows Vista

Finally I could get my USB programmer to work with windows vista. Firstly, I stripped of the breadboard from all previous connections, and reconnected the circuit. This ofcourse proved fatal to two of my microcontrollers, as I accidentally connected +12V to Vcc rail, instead of the input to the 7805 IC. I connected the programmer to PC, and it said unknown device. I knew I connected the D+ and D- wires from USB port wrong. The final bread board looks like this:

So I swapped them and replugged the USB. This time the device was recognised as usbasp, and windows vista asked for driver. I supplied the libusb driver given with the fischel’s package (http://www.fischl.de/usbasp/). Windows said something about device compatibiliy. I chose to ignore, and the device installed successfully.

Now I opened command prompt and typed  avrdude -c usbasp -p t2313

 Command prompt returned  error: could not find USB device “USBasp” with vid=0x16c0 pid=0x5dc

I tried to search the forums. They suggested to use 2007 build of winavr, I tried that (replaced avrdude.exe in the C:\winavr\bin directory with the 2007 version). Some of them also suggested to use an older version of libusb. So I did that too. After spending an hour, I did some thing I should have done a long time ago. I clicked on the orb (start), typed ‘cmd’, so Vista start menu searched cmd.exe. I right clicked on it and selected “Run as Administrator”. Now when I typed

C:\Windows\system32>avrdude -c usbasp -p t2313

found 8 busses

avrdude done.  Thank you.

 

Wow, the device actually worked!! I tried several times and it was working. I started the AVR8-Burn-O-Mat and changed some settings.

Burn O Mat seems to work fine too. Just too bad it doesn’t have the buffer of ponyprog, and the hex display. It is just great otherwist, and has a lot better fusebit editor.
