The XSUSB Board attaches to the parallel port connector of the XSA or XSB Board and converts it into a USB interface. Then you can use all the
XSTOOLs utilitiesthrough a USB port. This is especially useful for newer laptops which have no parallel port. And the USB link is much faster - anywhere from 2x to 13x faster on FPGA/SDRAM/Flash downloads and uploads!
