AVRDUDE can not find the USB port

Post by NanoGoner »

When I try to program an AVR through my newly functioning usbtiny, I use the following command line:

avrdude -c usbtiny -P USB -p m32 -U lfuse:w:0b11101111:m

and I get the following message:

"avrdude: ser_open(): can't find the device "USB". The system can not find the file specified"

I have tried downloading new Windows 64 bit drivers and looked everywhere I can think of to find a solution. Can anyone shed some light on this issue for me?
