The USBASP programmer is an important tool/accessory for embedded systems engineers/ firmware developers. It is a USB ICSP (In-Circuit Serial Programmer) that allows developers to easily upload firmware/bootloaders on AVR microcontrollers. Unlike what you find to serial programmers like the USB-TTL converters, it does not use a dedicated chip as it runs on an atmega88 (or atmega8), and uses a firmware-only USB driver with no special USB controller required.

The Arduino UNO is to be flashed with ArduinoISP for it to function as the ISP programmerUse the Arduino IDE to check for the correct USB port .\avrdude.exe -C .\avrdude.conf -p m8 -c avrisp -P COM7 -b 19200 -U flash:w:usbasp.atmega8.2011-05-28.hex:i
Hi,I use ATMega8's in a lot of projects because they are available locally but as previous responses have said, get yourself an Arduino UNO first, it makes everything else so much easier including burning the Arduino bootloader onto ATMega8's.
I searched everything but weren't able to find an answer. And yes, it should be the right serial port (in this case it is com4)and I tried diffrent Board settings ( but it should be NG or older boards with atmega8)

I wonder which hardware will be the best for playing with USB because its looks like a lot of projects only use atmega8 (or even attiny). But would it really be easier with an AT90USB which have the built-in USB?
AVR based 25 buttons joystick programmable from linux can be one of those projects: USB has many standard device classes, and HID is one of them, convenient for keyboards, mices and joysticks, especially since all operating systems support it, which means that you don't have to provide driver for your device. You don't need to know the low level side of USB/HID if you use such example projects, but you can find a lot of info at USB official site and documentation.
The Arduino project was started at the Interaction Design Institute Ivrea (IDII) in Ivrea, Italy.[3] At that time, the students used a BASIC Stamp microcontroller at a cost of $50. In 2003 Hernando Barragán created the development platform Wiring as a Master's thesis project at IDII, under the supervision of Massimo Banzi and Casey Reas. Casey Reas is known for co-creating, with Ben Fry, the Processing development platform. The project goal was to create simple, low cost tools for creating digital projects by non-engineers. The Wiring platform consisted of a printed circuit board (PCB) with an ATmega128 microcontroller, an IDE based on Processing and library functions to easily program the microcontroller.[5]In 2005, Massimo Banzi, with David Mellis, another IDII student, and David Cuartielles, extended Wiring by adding support for the cheaper ATmega8 microcontroller. The new project, forked from Wiring, was called Arduino.[5]
This project is a USB joystick controlled by a PPM radio remote control transmitter. There are a lot of such projects around based on different MCUs and USB drivers. But this one is Open Source. It provides very accurate PPM handling and a number of filtering options. Home constructors will like the optional servo tester mode and ADC interface instead of PPM for self-made control boxes.
This is basically a controller which can switch 16 LEDs arranged in a 4 x 4 array. It comes with a plugin for Cruise Control .Net, a Continuous Integration Server, so that it can visualize the build status for up to four software projects.
CP2102 is single chip USB to UART Bridge by SiLabs. This chip can be used to connect your embedded applications to USB port and enable them to transfer data with PC. It is the easiest path to build PC interfaced projects, like a PC controlled robot. We have a very good CP2102 module that can be used right out of the box. We have done all PCBs and fine SMD soldering for you.
So I took the bootloader that came with the Arduino IDE. It can be found at /arduino-0010/hardware/bootloaders/atmega8/ATmegaBOOT.c.You can try to call make to compile the bootloader or take the precompiled ATmegaBOOT.hex file. I needed to adapt the DIRAVR path setting in the Makefile to make it work. I used only the compile target, so I just typed 2ff7e9595c
