This e-mail is not for Graeme Gill. Since it's about a packed version of argyll. There is a problem with dispread 1.1.0rc4 and i1pro in the ubuntu package from https://launchpad.net/~pmjdebruijn/+archive/ppa I will not be surprised if this relates to other libusb stripped package too. When I run dispread it stop the measurements at about patch 340 and just hangs there. When I use the binary provided from Gill there is no such error. I have attached two debug logs. I have tested this 6-7 times and with different ti1 files and it's almost the same every time. Lars Tore Gustavsen
