Default USB 2.0 controller using ISP1581 device

Hello guys,

I have been implementing a high speed controller for USB 2.0
communication on Xilinx VirtexII FPGA, which interfaces to USB bus
through Philips ISP1581 device. I don't know how to go about it as I'm
a very new to USB stuffs.

I have got a choice of using MicroBlaze softcore microprocessor, but
currently, I'm encountering lots of trouble downloading it onto the
FPGA using already written C-code for ISP1581 device.

So, I would be grateful if you could be able to give me some
suggestions or directions on how to go about it. I wonder, if USB 2.0
core is available for ISP1581 device.
