You might have to open it up to know that for sure, it may just be holes
in the board and you will need to solder in the jumper or some short
wires.

There seem to be quite a few of the 'usbasp' boards out there, even at 5
euros they are a waste of money.

You may have to do that again.  Look around your neighborhood find an
old computer, install a basic version of Linux (no GUI), install
avrdude, find that DAPA programmer or just an old parallel printer cable
(you can cut the printer end off, just strip the wires and push them
into the usbasp 10pin connector), you will need a 5volt power supply
since you will need to disconnect the usb end of the usbasp.

The following link has detailed instructions on updating the usbasp:

If you break it open carefully you might be able to glue it back
together.

The red colour indicates pin 1, that is standard.  


Happy hacking.
