I went to the link printed on the circuit board and followed it here:
http://www.aliexpress.com/store/product/1LOT-1PCS-USBasp-AVR-Programmer-1PCS-CNT-004-Adapter-1PCS-10PIN-65CM-Wire-Free-shipping/812021_1087050891.html
it says that this usbasp is modified to automatically find the correct
speed so use the latest avrdude but leave out the -B switch, like this:
$ sudo avrdude -p t2313 -c usbasp -v
Don't forget the correct wiring.

The above link says that this unit is modified from the opensource
version on the fischl.de site so the information there doesn’t quite
apply.
