In setting up a new computer system, I grabbed WinAVR 20100110, and installed. Then I installed my USBtiny drivers and libusb.

To test, I loaded an existing project (which works on my old dev machine, with a WinAVR version from 2008). When trying to run avrdude, however am told:

avrdude -p attiny25 -c usbtiny    -U flash:w:buck.hex 
avrdude: error: no usb support. Please compile again with libusb installed.
avrdude: programmer operation not supported
avrdude: programmer operation not supported

avrdude done.  Thank you

Is this correct? Was the included avrdude (5.8cvs) compiled without USB support?

Apparently yes, see the other threads about it.

Huh... I guess my search-fu is weak, I didn't see other threads. I'll have to go look some more...

I found a quick and easy workaround... I copied avrdude.exe and avrdude.conf from an older version, and all is well.

Try downloading the new avrdude (5.9)
