The library is called libusb-driver as it was developed to support the USB cable, but later
extended to also support parallel cables.

+ - 2008-03-26: Xilinx has released their own drivers based on libusb with ISE Design Suite 10.1.
+ To use them, you need to set the environment-variable XIL_IMPACT_USE_LIBUSB to 1
+ before running the tools. The driver on this page no longer needs to be preloaded if you only used
+ it to access USB cables. Parallel port support still seems to rely on windrvr, which can be
+ emulated by libusb-driver.

Using 32-bit ISE 10.1 on a 64-bit platform: When using the 32-bit JTAG tools from ISE Design
+ Suite 10.1 on a 64-bit machine, the tools will not connect to the cable but output the following
+ error: Cable operation is not supported when running the 32-bit version of the application on a
+ 64-bit platform.
+ To fix this, run the tools with linux32 or preload the newest 32-bit version of
+ libusb-driver. This will lead the tools to believe that they are running on a 32-bit
+ platform and allows them to connect to the cable.
+
+ - 2009-05-31: ISE Design Suite 11.1 now uses their libusb based drivers as default, without
+ the need to set XIL_IMPACT_USE_LIBUSB. If you want to use this driver with ISE 11.1 for USB
+ cables and disable the builtin support for libusb, you now have to set XIL_IMPACT_USE_LIBUSB
+ to 0 (export XIL_IMPACT_USE_LIBUSB=0 or setenv XIL_IMPACT_USE_LIBUSB 0).
+ For parallel cables Xilinx still relies on windrvr. This library works fine with parallel cables and
+ ISE 11.1 with no need for windrvr.

Supported Cables
The following cables are reported to work with this driver:
