USBasp is a USB in-circuit programmer for Atmel AVR controllers. It is based on Thomas Fischl's USBasp design project. The driver will work on both 32 and 64 bit platforms. For Linux and Mac OS X no driver is required, just use AVRdude and specify the correct port. Support for Windows, Mac OS X and Linux. USBASP V2.0 User Guide; AVRDUDE supports USBasp since version 5.2. BASCOM-AVR supports USBasp since version 1.11.9.6. Khazama AVR Programmer is a Windows XP/Vista GUI application for USBasp and avrdude. EXtreme Burner – AVR is a Windows GUI Software for USBasp based USB AVR programmers. A command line light weight dfu-programmer can also be used. USBAsp AVR Arduino Programmer Drivers There are a few variants of the USBAsp, mostly they work the same and need the same drivers. This guide is for the ones that look like this, but as I say mostly they work the same so try it anyway.

USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply consists of an ATMega88 or an ATMega8 and a couple of passive components. The programmer uses 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 (< 1,5MHz).
