Anyways, while searching for 'fully signed USBasp driver', I came. This page http://www.protostack.com/accessories/usbasp-avr-programmer. However, if you're using a USB-serial adapter (which lets you use an STK500 or AVRISP v1 with a Mac) then you'll need to specify the serial port. I don't know a foolproof way yet but the way I do it is in the Terminal I type in ls -l /dev/cu. and it will spit out a bunch of stuff (I screwed up the screen capture, this image has another window.
Hi everyone, first post here on AVRfreaks:DUp until recently I've been using my trusty old copy of windows XP to burn code to AVR's with a USBasp, avrdude 5.4 and AVRstudio 4. Recently I installed Windows 7 on my computer, and after re-installing AVRstudio and AVRdude, I found that AVRdude would no longer recognise my USBasp. And keeps coming up with 'error: could not find USB device 'USBasp' with vid=0x16c0 pid=0x5dc'.I was a bit confused for a moment before I realised that I hadn't yet installed the drivers for the USBasp. But here's the problem, Windows 7 refuses to accept that the drivers I'm offering it are drivers at all! It just says 'Windows could not find driver software for your device' whenever I direct it to the folder where the drivers are.can anyone suggest how to fix this?
Google has turned up nothing upon searching for USBasp win7 drivers. I have found an alternative solution as well.1. After you install the driver and Windows 7 (64-bit) complains that it is not signed, reboot2. Tap the F8 key during the windows startup to get to the safe-boot options screen.3. At the bottom of the list of boot options is the option to disable driver signing checks.You will need to do this every time you want to use the driver. During this time it is possible to install all manner of dodgy unsigned drivers which can pollute your kernel, so be warned.At the moment I am embarking on a mission that may let me compile and self-sign. But I suspect it's doomed.

The version I use is one with ATmega8.Thank you!EDIT: Disrecard this message.
I realised i just have to use the inf-wizard to get it installed.Its hilarious to realise that you have used four hours and there was this simple answer.:). I'm also using USBasp here. The only difference is the device I bought directly from China. Works well.What I had to do is to install drivers by going to Device Manager - Right click on your computer icon at the top - Install Legacy hardware.Worked on 32 and 64-bit versions of Windows 7. There is a package which has all the drivers too. I believe it uses standard USBasp drivers. You can search for ProgISP or PowerPrg.
You should be able to get drivers and programmer software in one package.Hope this helps.

USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simplyconsists of an ATMega88 or an ATMega8 and a couple of passive components. The programmeruses a firmware-only USB driver, no special USB controller is needed. Features. Works under multiple platforms.
Linux, Mac OS X and Windows are tested. No special controllers or smd components are needed. Programming speed is up to 5kBytes/sec. SCK option to support targets with low clock speed (.
