Subject: [PATCH] Add setup script for USB cable which works on modern
 distributions

This completely rewritten version of setup_pcusb works on modern
distributions with newer udev versions which have a different
rules-format and are not detected by the xilinx-version of the
script. It only has the name in common with the xilinx-version.

 these steps:
 
+1. Run ./setup_pcusb in this directory, this should set up everything

+   - When $XILINX is set correctly:

+Old instructions, use only when the above script did not work:

 1. If you have no /etc/udev/rules.d/xusbdfwu.rules file, copy it from
