This interface (as it is build-in on the sockit development board) is composed of a Cypress EZ-USB plus a CPLD. The Cypress chip as an embedded 8051 microcontroller. When it's powered up, the firmware is downloaded to the chip then the device is disconnected and reconnected with the new firmware. The USB-Blaster II protocol is almost identicial to the old one. The only difference is that you need to send a 0x5F before read TDO back. This command seems to copy TDO buffer datas to the endpoint buffer. Driver will be auto enabled if libusb-1.0 is detected.
