Graeme, Scott,
thanks for your help. I think things actually work for me. I get
measurements doing:
./dispcal -y l foo
Even though I can't find the /dev entries but that doesn't seem to
matter.
I leave my answers below for completeness since I'm sure somebody will
come to the archives with the same questions.

Hmm, what exactly is the "Argyll driver"? Is that a kernel module? I
thought you talk in bytes over a generic driver to the USB device
without your own kernel module?

It's too long for mailing list mail, so I copied it to:
http://www.cons.org/tmp/spotread-huey.txt
Thanks for your help so far. I'll now rebuild Argyll, currently I'm
using the binaries that don't have dispalGUI. But it looks like I
don't have a driver problem here.
