+This is actually a very poor interface and not recommended. The design of the K8062 means that it can only transfer 8 bytes of data every 10ms over the USB port, leading to a max frame rate of 1.6 full DMX frames / second. The Velleman USB protocol uses a simple form of compression which results in frames having a large number of 0 byte channels being sent faster.

 The above statement is false. If you take the code mentioned above and insert timing information it takes ~800ms to write 512 bytes of non-0 DMX data:
