Thank you for taking time!  A few additions and corrections.  Feel free
not to include them if they are irrelevant to your document.  It's just
for your information.

I put slightly improved version of prism2dl here:
http://www.red-bean.com/~proski/prism2dl/

It should be easier to use, but it's not _safer_ to use than the original
version.  In particular, it still allows flashing firmware intended for
RAM download.

Upgrading primary firmware without secondary firmware make the card
non-functional.  That card acts as if it only has primary firmware.  The
secondary firmware should be flashed after that.  prism2dl is good for
that, prism2_srec is not (yet).  I haven't tried winupdate.  The DOS based
flash.exe should be OK.

prism2_srec cannot be used to upgrade primary firmware because it cannot
upgrade both firmwares in the same time and it cannot deal with a card
without working secondary firmware.

You probably should specify what Windows driver should be installed.
winupdate is picky.  I know that the driver for Linksys WPC11 v2.5 is OK.

The latest primary firmware for USB devices appears to be 1.1.2, but it's
not available for other devices.
