LIMESDR-FPGA USB connection

Dear All,
We have several DSP IP’s prepared for Xilinx FPGA. We want to test them with LIMESDR or LIMESDR mini.
We plan to connect the LIMESDR or LIMESDR mini into the USB Host of an FPGA board.
What we could not figure out is how to get the Stream for the USB and convert it to 10 bit I&Q + CLK which our DSP IP’s need to process the data.
Has anyone tried this before?
We guess that we can install GNU RADIO inside a ZYNQ FPGA’s ARM processor and get the data but sending it to the FPGA and converting it to I&Q + CLK is above us for now.

Any help is greatly appreciated
