USBAsp Too Fast? Slow it down

If your USBasp has problems communicating, it may be due to too fast USB speeds. Try this in your avrdude config files for an alternative:

usbaspslow.name=USBasp Slow  
usbaspslow.communication=usb  
usbaspslow.protocol=usbasp  
usbaspslow.program.protocol=usbasp  
usbaspslow.program.tool=avrdude   
usbaspslow.program.extra_params=-Pusb -B5
