Something more sophisticated will happen someday, this is what we have
now.

Then the person doing the HID code fix should remove the blacklist entry
at the same time.

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.

There is also possibility (for quite a few releases already) to change the
quirk list in runtime. See the 'quirk' parameter to the usbhid module.

What exactly is the problem here? I didn't seem to catch the beginning of
the thread (or it happened off the list I am subscribed to).
I will apply the patch to my tree, thanks.

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.
