Just made an USBasp. It's a USB AVR in-system programmer project by Thomas Fischl. Used the PCB by J.A. de Groot found on the USBasp project page. Had to add 2 missing zeners, but other than that the build was straightforward and problem-free.
This programmer handles USB communication in firmware on an AtMega8 or 48.
Tested with ATTiny2313 and ATMega8 sofar. Works fine.
No need to bother with the LPT port anymore.
