[sane-devel] Re: Artec 1236USB

[Theodore Kilgore]

Henning and Gerhard,

Thanks for the tips. We will work on it and try to get back to you about
it. I have forwarded your messages to the owner of the scanner.

Meanwhile (off topic?):

Someone wrote in a few weeks ago about USB cameras. Well, I bought a cheap
one day before yesterday, a "Gear to Go" which cost $18. It has vendor id
0x2770 and sorry that I can't give the product id from memory.  Last night
I broke it by taking it apart and looking inside (where I found nothing I
can report about, except there is a Samsung memory chip in it). It did
report class:subclass:protocol of ff:ff:ff, I do remember that much. I did
manage to set it up on a Windows box, though, and do a sniff. It did work,
then, once, before meeting its nemesis. It installed stuff related to
TWAIN in Windows.

So, anyway, does anyone know who is doing things like this? Presumably it
is not part of the SANE project even though closely related? I know
someone else asked this recently, sorry, I think I deleted that message.
