 The closest alternative to the BusVoodoo is probably the [[http://dangerousprototypes.com/docs/Bus_Pirate|Bus Pirate]], and this is actually the device I used for a long time before I decided to make my own because the shortcomings piled up. The closest alternative to the BusVoodoo is probably the [[http://dangerousprototypes.com/docs/Bus_Pirate|Bus Pirate]], and this is actually the device I used for a long time before I decided to make my own because the shortcomings piled up.
