FAQ

• The error: avrdude.exe: error: no usb support. please compile again with libusb installed ?

You may need install winavr to use avrdude to connect this programmer properly, this error caused by an old version of avrdude

• What does that section mean when it says "cannot set sck period"?

This is fine. Many Chinese usbasp firmwares detect the SCK speed automatically. Hence they do not respond to avrdude setting SCK. This is very handy for you because any virgin AVR needs to be programmed relatively slowly ( 1MHz needs -B5 ). Your usbasp uses the best speed that it thinks is suitable.
