If you don't have 3.6V zener diodes on your LCD2USB, try plugging your
LCD2USB into a USB hub and the USB hub into your computer. If you
_do_ have 3.6V zeners, I did catch a note that some of the early ones
recommended are too slow (which result in a lot of "-71" errors in the
logfiles when you connect the LCD2USB). You could remove the 3.6V
zeners then use a USB hub.

Other than that, see if your LCD2USB works on other computers - I know
that mine behaved differently on an HP Workstation vs a Macbook Pro
(solved by using a hub).

If the device does not enumerate when connected, it doesn't matter
what software you have - fix that problem first.
