Just in case it might interest you, here's a new bug which appeared when I used argyll built against the distribution libusb (did not happen with custom libusb): in spotread, with the Rev. D Eye One Pro, instrument calibration always fails:
Which version of libusb did you link against ? It's almost certainly a bad idea to link against some other version of libusb than the one I supply with the Argyll distribution. I've modified it to fix some issues with specific instruments, and I've qualified that particular version to work with the supported instruments. In my (growing) experience, interactions between instrument and the USB systems are rather fragile. Changing something like the version of libusb is not to be undertaken lightly - it has a high chance of breaking things, so if you're going to do this, you need to be prepared to re-test all the instruments, to make sure there are no regressions. If you're not going to do this testing, then please don't attempt to switch to some other version of libusb. Graeme Gill.
