I have been using Windows 8 on my Lenovo Ideapad for some time now. It is fair to say that Windows 8 has been the unlucky recipient of a huge amount of criticism and it is also fair to say that this criticism has been fair. So when Windows 8.1 Beta came out I could not resist its pull for too long and decided that installing a possibly buggy beta was preferably to tolerating the mess that is Windows 8 for any longer…. Then I tried to program an ATtiny85 and found the drivers did not work! Happily I fixed it.
The USBtinyISP programmer is an AVR in circuit serial programmer that I purchased from Adafruit some time ago. As it is based on libusb creating Windows drivers turned out to be pretty easy. I simply downloaded the driver set via http://www.libusb.org/ and then used the inf-wizard.exe to create updated drivers.
You can find the drivers on my Github page here… https://github.com/Justblair/USBTinyISP_126.96.36.199
These are not well packaged and even less well tested, but I got my programmer working using them. I installed them with the Windows 8.1 with “disable driver signature enforcement” though as I understand it this should not be required to do this. I used the update driver tool in Windows device manager to install the driver. I have left the installation programs in place but they are untested.
Hopefully I can save someone else some head scratching with this updated driver package
