+Notes for FTDI 2232 based cables
+================================
+
+To build the driver with FTDI 2232 support, you need to have libftdi and
+the libftdi development package installed. On debian, you can install both
+by installing 'libftdi-dev'.
+
+To set-up the device:
+1. Find out the vendor and product id of your cable using lsusb:
+   Bus 003 Device 005: ID 0403:cff8 Future Technology Devices ...
+                          ~~~~~~~~~
+
+2. Copy the sample libusb-driverrc to ~/.libusb-driverrc, edit it and replace
+   the vendor and product-id in the example file with the values provided in
+   the lsusb-output. You can also change the 'parallel port' which is mapped to
+   this cable. Impact sees the device at that port as a Parallel Cable III.
+
+3. To use the device as an ordinary user, put the following line in a new file
+   in /etc/udev/rules.d/ and restart udev:
+   ACTION=="add", BUS=="usb", SYSFS{idVendor}=="0403", SYSFS{idProduct}=="cff8", MODE="666"
+   (replace the vendor and product id with your values)
+
+The support for FTDI 2232 based devices is experimental and they are currently
+significantly slower than the other supported cables.
