Please excuse my ignorance; hopefully this is [remotely] related to your problem: I did find that I can't use libusb to change configurations (nor select an interface) without running as root. There is a way to set permissions for the usb ports; quite a few explanations are available on the web.
so try 'su' before running avrdude... if it works then try setting up the port perms. Hope this is related & of some help. Regs.
