Can't help you here. Is it OHCI compliant? Do you know what chipset it
uses? It might be visible on the card, or run lspci.

I'm going to buy this dude too! Or, the QPS iBot. I think the iBot does
DV, and I already have a miniDV cam, so I should probably diversify my
devices.

The writer of video1394 and some others on the devel list are using
uncompressed cameras for machine vision applications, so there is work
being done. There is a libdc.sourceforge.net project that provides a
Digital Camera protocol library. However, there are no readily available
applications that I'm aware of.

I am currently working on DV grabbing and recording in conjunction with
Arne Schirmacher using the OHCI DMA implementation in video1394.
Eventually, I intend to marry the code of Xmovie with my video1394
capture routine to simply reflect the video transmission to a window.
Xmovie uses the Xv extension in XFree86 4.0.x that utilizies the direct
video playback capabilities of display adapters. (Currently, I am only
aware of the Matrox G200/G400 driver that supports this feature.) I am
very interested in seeing just how direct I can get from the direct
memory access of OHCI to Xv! 

What applications are you interested in? Do you want to record to disk
or videoconference over the net? I think it will be a while until we see
a video conferencing application that works with 1394 cameras on Linux.
I can probably hack together disk recording, but that will be a couple
of months from now. Other projects are taking priority right now, I hope
you understand. Perhaps someone else will beat me to the punch.
