The XillyUSB driver is the USB variant for the Xillybus FPGA IP core. Even though it presents a nearly identical API on the FPGA and host, it's almost a complete rewrite of the driver: The framework for exchanging data on a USB bus is fundamentally different from doing the same with a PCIe interface, which leaves very little in common between the existing driver and the new one for XillyUSB.

Xillybus is a generic interface for peripherals designed on

|
programmable logic (FPGA). The driver probes the hardware for
|

its capabilities, and creates device files accordingly.
