 To use the device as ordinary user, put the following line in a new
 file in /etc/udev/rules.d/ and restart udev:
 ACTION=="add", BUS=="usb", SYSFS{idVendor}=="03fd", MODE="666"

+If your cable does not have the ID 03fd:0008 in the output of lsusb,
+the initial firmware has not been loaded (loading it changes the
+product-ID from another value to 8). To load the firmware follow
+these steps:
+
+1. If you have no /etc/udev/rules.d/xusbdfwu.rules file, copy it from
+   /path/to/ISE/bin/lin/xusbdfwu.rules to /etc/udev/rules.d/xusbdfwu.rules
+
+2. Install the package containing /sbin/fxload from your linux distribution.
+   It is usually called "fxload"
+
+3. copy the file /path/to/ISE/bin/lin/xusbdfwu.hex to /usr/share/xusbdfwu.hex
+
+4. restart udev and re-plug the cable
