+ <LI><P><I>2008-03-26</I>: 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 <kbd>XIL_IMPACT_USE_LIBUSB</kbd> to <kbd>1</kbd>
+ 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 <i>windrvr</i>, which can be
+ emulated by <i>libusb-driver</i>.</P>
+ <P><B>Using 32-bit ISE 10.1 on a 64-bit platform:</B> 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: <I>Cable operation is not supported when running the 32-bit version of the application on a
+ 64-bit platform.</I>
+ To fix this, run the tools with <KBD>linux32</KBD> or preload the newest 32-bit version of
+ <i>libusb-driver</i>. This will lead the tools to believe that they are running on a 32-bit
+ platform and allows them to connect to the cable.</P></LI>
+
+ <LI><P><I>2009-05-31</I>: ISE Design Suite 11.1 now uses Xilinx's libusb-based drivers as default, without
+ the need to set <kbd>XIL_IMPACT_USE_LIBUSB</kbd>. 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 <kbd>XIL_IMPACT_USE_LIBUSB</kbd>
+ to <kbd>0</kbd> (<kbd>export XIL_IMPACT_USE_LIBUSB=0</kbd> or <kbd>setenv XIL_IMPACT_USE_LIBUSB 0</kbd>).
+ For parallel cables Xilinx still relies on <i>windrvr</i>. This library works fine with parallel cables and
+ ISE 11.1 with no need for <i>windrvr</i>.</P></LI>
+
+ <LI><P><I>2010-03-15</I>: If you are using newer udev-versions (like the version included in Debian Squeeze
+ and Ubuntu 9.10), then the file <i>/etc/udev/rules.d/xusbdfwu.rules</i> is incompatible with this udev
+ version. The effect of this is that the cable-firmware gets never loaded and the cable led never lights up.</P>
+ <P>To fix this, run the following command as root:<BR>
+ <kbd>sed -i -e 's/TEMPNODE/tempnode/' -e 's/SYSFS/ATTRS/g' -e 's/BUS/SUBSYSTEMS/' /etc/udev/rules.d/xusbdfwu.rules</kbd><BR>
+ You may have to reboot for this change to take effect.</P></LI>
+
+ <LI><P><I>2010-05-22</I>: Support for ISE 12 is now available in the driver.</P></LI>
+
+ <LI><P><I>2011-05-08</I>: Support for ISE 13 is now available in the driver. A rewritten version of <i>setup_pcusb</i>
+ which works on modern distributions has been added.</P></LI>
