AVRISP mkII libusb drivers for Windows 7 / Vista x64

Continuing on the theme of my last post, here are libusb-win32 drivers for the Atmel AVRISP mkII. Unlike the Atmel-supplied drivers, these support avrdude, and as a bonus they will install on the 64-bit version of Windows 7 without digital signature errors. Yes!


Note that if you want to use the AVRISP mkII with AVR Studio, these are not the drivers you are looking for. You want the ones Atmel provides (if you installed the libusb drivers by mistake, re-run the AVR Studio installer to revert back).

  1. Is this driver having some problems with CrossWorks from Rowley? I installed them properly, the driver itself was OK, but when I tried to connect to it via activated CrossWorks, it told me to reinsert the programmer. The problem persist after doing so…

  2. It doesn’t seemed to work on my AVR Studio BETA 5 and avr dude even the driver was installed… can you give me an idea to fix this…?
