Xilinx ISE libusb driver.

Are there any FPGA developers out there?
If so, I was wondering if you can help me.
I am attempting to use the libusb drivers to program FPGA devices via the platrom cable USB programmer. The green light comes on the programmer and I am able to initialize the JTAG chain. When I goto program the device, it is painfully slow and when complete the done light is never set on the FPGA development board. With all the same setting it appears to work in windows.

Just wondering if anyone else has had this issue and if so, where they able to fix it in any way?
