+FXLOAD UTILITY
+
+This program is conveniently able to download firmware into FX, FX2,
+and FX2LP EZ-USB devices, as well as the original AnchorChips EZ-USB.
+It is intended to be invoked by hotplug scripts when the unprogrammed
+device appears on the bus.
+
+Primarily as an aid for developers, this can also be used to update
+firmware on devices which boot from I2C serial EEPROMs.  For that
+use, as well as downloading firmware to all other off-chip memory,
+a second stage loader must first be downloaded.
+
+The distribution includes "a3load.hex", which is a simple second stage
+loader that works with all the EZ-USB products listed above.  If you
+want to write to an EEPROM, you can use the appropriate version of the
+"Vend_Ax" code provided with the Cypress developer kit.
+
+
+UPDATES
+
+See the download page at http://linux-hotplug.sourceforge.net for the
+latest release.  The CVS repository there holds the most current version
+of this software.  The web site shows some ways to use "fxload" in
+conjunction with USB hotplugging, to load device firmware.
+
+Post any bug reports to the linux-hotplug-devel or linux-usb-devel lists.
+
+If you modify the code, the GPL requires that you make your updates
+generally available (under most circumstances).  Providing them in the
+form of patches against the current CVS ("cvs diff -u"), or the last
+release ("diff -u old new") is most useful, since otherwise it's awkward
+to integrate such changes into the standard distribution.
