-This library emulates Jungo Windrvr USB functions in userspace which are
-required by XILINX impact to access the Platform cable USB. With this library
-it is possible to access the cable without loading a proprietary kernel module
-which breaks with every new kernel release. It uses the USB functions provided
-by the libusb userspace library instead and should work on every kernel version
-which is supported by libusb. It was written against impact from ISE Webpack
-9.1SP1 and will very probably not work with older impact versions (<9.1).
+This library emulates Jungo Windrvr USB and parallel port functions in
+userspace which are required by XILINX impact to access the Platform cable USB
+and Parallel Cable III.
+With this library it is possible to access the cables without loading a
+proprietary kernel module which breaks with every new kernel release. It uses
+the functionality provided by the libusb userspace library for USB access and
+the kernel interface at /dev/parport0 for parallel port access instead and
+should work on every kernel version which is supported by libusb and supports
+ppdev. It was written against impact from ISE Webpack 9.1SP1 and tested with
+the following software:
+
+ * ISE Webpack 9.1SP2
+ * ISE Webpack 9.1SP1
+ * ISE Webpack 8.2SP3
+ * ISE Webpack 8.1SP3
+ * ChipScope 9.1.02i
+ * EDK 8.2.02i
Build the library by calling `make'.

+Notes for the USB cable
+=======================
+
+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}=="03fd", MODE="666"
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, create one with the
- following content:
-# version 0001
-SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="0008", NAME="windrvr6"
-BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="0007", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusbdfwu.hex -D $TEMPNODE"
-BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="0009", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusbdfwu.hex -D $TEMPNODE"
-BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="000b", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusbdfwu.hex -D $TEMPNODE"
-BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="000d", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusbdfwu.hex -D $TEMPNODE"
-BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="000f", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusbdfwu.hex -D $TEMPNODE"
+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

+
+Notes for the parallel cable
+============================
+
+To access the parallel port from userspace, the kernel needs to be built with
+the features "Parallel port support" (CONFIG_PARPORT), "PC-style hardware"
+(CONFIG_PARPORT_PC) and "Support for user-space parallel port device drivers"
+(CONFIG_PPDEV) builtin or as modules. If these features are built as modules,
+they need to be loaded before using this library.
+These modules are called:
+parport
+parport_pc
+ppdev
+
+
+To use the device as an ordinary user, put the user in the group 'lp'
+
+
+Parallel Cable IV is currently only supported in 'compatibility mode', as no
+attempt to configure the ECP registers is done by this library.
