Yes, that is issue 7: https://github.com/baerwolf/USBaspLoader/issues/7

Long story short: You should use a recent toolchain - the old ones are buggy.

Many thanks to vouvoume!
The Board is running now!

It seems to be an error in the Schematic:

USB D-MINUS is connected to PD7 and not PD0 (like shown in the Schematic)!

Again many thanks to vouvoume!

Hi everybody.

I do not know how good google-translate will work.
But at least for all Germans speaking people: There is a very rich thread about the ATmega32 Minimum System Board in the German Mikrocontroller forum, see here: http://www.mikrocontroller.net/topic/288940#new

There you also can find working and precompiles example firmwares for the different version of the board, in order to get the USB up and running.
