I think we'll need a database of those anyway, could we use someone's
hospitality and list the usb/usbd debug output and whoever may have
an interest in that particular entry (a little like /lib/vgadb) on
a globally accessible server?

We'll also probably need a /lib/vgadb definition file for all the
quirks that USB devices seem to suffer from (I have a document that
covers foibles in CBI devices, a google find I'm sure I can repeat).

They are, aren't they (give or take "bootability" which seems to
have lost track altogether)?  I've collected a good few of their
documents but the 650 pages standard is not one I'm ready to print
just yet.

I would like to set up a special interest group, if that's OK with
anyone else who's interested, but not really a separate mailing
list unless the traffic starts swamping other interests here.

Nemo, you're much more familiar with the kernel code, could you
look into the bit I suggested, where a USB utility merges a kernel
function (ATA is my immediate interest) with the USB device,
analogously to the ip/ipconfig does?  I'll be thrilled to implement
the ideas, if you can set me on the right track.

Anyone else wants to play?  I should think a small reflector of
interested individuals for comparing notes would be sufficient?
