Hi, I just got a Lenovo ThinkPad W530 with a builtin color calibrator. The current argyllcms-1.4.0 doesn't recognize the colorimeter. It appears to be an "X-Rite integrated color calibrator" (http://www.lenovo.com/products/us/laptop/thinkpad/w-series/w530/) I didn't see any thing in the ArgyllV1.4.0 code or the rules in Argyll_V1.4.0/libusb/55-Argyll.rules that matched the device. I am willing to try experimental code and locally compiled code to get the colorimeter working Argyllcms running on Linux. The following is the lsusb verbose output for the device. $ lsusb -d 0765:5010 -v Bus 002 Device 003: ID 0765:5010 X-Rite, Inc.
