3pi/programmer not working

Hi im Janne Kaihlamäki from Finland.

My problem is that my avrdude, avr studio or winavr cant communicate with pololu usb programmer (that old one) only way i have had some success was with pololu serial transmitter.

(avr studio4)
Says connection failed.

C:\Users\Kaihliss>avrdude -p m168 -P \.\USBSER002 -c avrisp -e
avrdude: ser_open(): can’t open device “\.\USBSER002”: The system cannot find the file specified.

Same with 000-010, avrispv2 and avrisp2…

Programmer is connected properly and 3pi has over 5500 mV
drivers installed (many times) all LED’s glowing that should be.

Windows 8.1
Couple years ago managed to program my 3pi so it is working.

Thanks for your help Janne Kaihlamäki.

Hello, Janne.

I am sorry you are having problems with your AVR programmer. Which AVR programmer are you using? Also, can you send me a screenshot of your Windows Device Manager?

This is not an appropriate way to ask for help or a refund. For issues with orders, you should contact us directly with your order number and what is wrong with the items (hint: what you have here would not be anywhere near enough for a return). If you want help, please post more information about your problem; we would be happy to help you troubleshoot.
