Hi l got my Pocket AVR Programmer yesterday and installed the drivers smoothly by using this commment:
I am running on a Win7x64bit and using AVRDude from WinAVR to download .hex files from BASCOM demo.
A proper solution for running under Windows 7, including 64 bit, without turning off driver signing.But when I tried to program with it I get the rc=-1 error.
Download the windows driver from sparkfun, and unzip it somewhere.
Download a recent libusb release from sourceforge: http://sourceforge.net/projects/libusb- ... -releases/ and unzip it somewhere.
Take the libusb0.dll and libusb0.sys files from the sourceforge bin\amd64 directory, rename them to libusb0x64.dll and libusb0x64.sys, and replace those files in the sparkfun driver directory.
Replace the sparkfun libusb0.sys and libusb0.dll with copies from the sourceforge bin\x86 directory (renaming the sourceforge libusb0_x86.dll to libusb0.dll).
Your driver is now ready to go. Windows will complain during the install that the drivers aren't signed, but they actually are. Once installation is done, Windows will happily load the new drivers.
Sparkfun: please update those four files in driver zip file. That will fix it for everyone.
