This worked for me to setup the connection between two USBasps.
Then I used the information from the thread I posted about the Alpha firmware.
Checkout the Readme and it will walk you through the different steps.
"This is the README file for USBasp.
USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply
consists of an ATMega48, 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.
automatically determines working SCK speed when SCK rate not specified
(i.e if -B option in avrdude is not specified, device will auto select clock)"
