If you get the MX-USBISP-V3.00 boards that don't have the three solder bridges then they are super easy if you have two or more.

Just use one as programmer and the other as target, connected by the 10 pin cable that comes with them.

Jumper the target between the indicated vias (a cut leg from a 0.1uF capacitor makes a perfect removable jumper).

Get the standard Atmega8 latest firmware from fischl.de and flash using avrdude with 'usbasp' as programmer.

I set up various DOS batch files for testing connection, backing up original firmware, restoring original firmware and flashing the new firmware.

Once set up. it literally takes about 20-30 seconds to jumper a programmer, plug it in to the ribbon and double click the batch file to flash the latest firmware.

Once set up
And that is the big step for many folks
since there are so many different versions of the circuit and PCB layout floating around out there
and many people don't want to take the time to analyze their PCB and put their
tools in place to do the update.
As with many things in life, the actual time to do the task is minimal, it is
the prep work that takes all the time.

Up date firmware usbasp betemcu.cn

first down load file firmware for betemcu.cn
prepair the usb-FT232  or usb basic breakout for update  firmware.
connect j2 on usbasp betemcu and connect to usb ft232 via isp port.
open software for upload firmware
load firmware file for update do upload till done.

after that usbasp can work on eXtreme burner and AVRpal.net

download file for update firmware "arduino as usb asp.zip on google

  notebook with wind7 64bit----->USB basic breakout------------>usbasp betemcu.cn (J2short).

I was test to upload bootloader ATMEGA8 on STK200.

Hey guys and gals. Wondering if I can get some help here. I am trying to upload simonk firmware to my ESC for my quadcopter, and can't seem to get my usbasp working. I have tried several different ways, but I think it is a problem similar to what has been discussed in this thread so far, but its over a year old, and I can't really follow everything or know if it is still viable advise.

here is what I bought.http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=300956937549
and here is what I got
As you can plainly see, not the exact same thing, and the listing shows a jumper, and mine has nothing.

Now I have several tools available to me but I am not super tech savvy when it comes to hardware.

I have a FTDI USB adapter that is known working. I have used it to upload to Pro Mini so I know it works.
I have several pro mini 5v boards, 2 Unos and a mega and even a decimilanova or however you spell it.
I bought this http://tinyurl.com/o3cxma3 socket adapter from Hobbyking and would have bought the companion usbasp from them also, but they have been out of stock for a while now. I figured that this ebay one suffice.

If anyone can help me either get this usbasp/isp thing I bought to work, that would be amazing. if there is a way I can wire that socket adapter to an arduino and upload new firmware to my Multistar 30A ESC http://tinyurl.com/l9ts8wb, i am fine with that too.

Help me, and I would be grateful.

See my reply #34 earlier in this thread, http://forum.arduino.cc/index.php/topic,149668.msg1138408.html#msg1138408.

The main point is you will need to short the to holes pointing to "UP".  Then connect up the header to another ISP programmer to upload the new image to the atmega8.  Similar to reply #38, http://forum.arduino.cc/index.php?topic=149668.msg1200311#msg1200311.
