For more info on usb colorimeter problems you can check http://www.freelists.org/archives/argyllcms/12-2007/ It seems Graeme Gill, the Argyll CMS author has hit several linux usb problems over the years but has not coordinated well with the Linux usb maintainers. We're finding all the ugly bits now that we're trying to meger Argyll CMS in various distributions (Fedora, Mandriva, Ubuntu, etc) It's a bit difficult to follow this thread because the argyllcms list is killing CCs and not everyone is putting them back in.

I'm not saying it does not work, I'm saying I don't want my users to fool with kernel modules when we know the default should not be HID for huey right now. If you prefer enhancing the kernel HID driver, and switching argyll to it, just do it. I don't care as long as I don't have to maintain workarounds distro-side. -- Nicolas Mailhot signature.asc Description: Ceci est une partie de message numériquement signée
