Hmm... I tried a different USB port and when Win7 re-installed drivers to support that port the device was recognized by dispcal. I went back to the original port, re-installed the drivers for the device (using "Update Driver 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: <http://www.argyllcms.com/ccmxmake.zip> 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.) Graeme Gill.
