Hmm... I tried a different USB port and when Win7 re-installed drivers to

Software..."), and it was recognized there too.

OK, something must have been wrong with your original driver install.

dispcal still isn't working properly though :(

When I run it, I see a gray box and I press a button to begin the
measurement. The gray box flashes a bit (I think) and then quickly becomes
black. After a long pause (about a minute), dispcal exits and tells me that
my white and black level are the same (ie black)! Actually, the colors in
the box on the monitor never changed away from black.

Someone else has reported this sort of behaviour, but I've been unable
to figure out what causes it (it doesn't happen on my Vista 32/64 or Win764
test machine). Try using these versions of the programs instead:


and see how they behave. I'd be interested in a -D5 output from
one of these (ie. dispcal), if it behaves strangely. (The above versions
paint the screen slightly differently, and include some debugging of
windows events for -D4 or above.)
