Oh, sorry to hear that.  I really didn't think it would be that 
difficult.  These days I figured any modern point-and-shoot with a macro 
mode (the flower icon in the shooting mode list) should do it.  The 
pictures I've taken:

were done with a DSLR bought back in 2005 (along with a cheap halogen 
desk lamp for illumination).

If you want to send me the AVC-3610 I'll take a shot at it.  However 
right now for the next few months I am totally swamped on another 
project (this one pays bills).  So no hurry.  I am interested in trying 
to integrate support for this device however because you're not the 
first one to ask.  If you'd like to do that we can exchange direct 
contact information off the list (e-mail to isely at pobox.com or 
isely at isely.net or both)

Ah!  That's *very* useful to know.  My concern about this device is how 
a single FX2 (that's the Cypress chip) could be handling two video 
paths.  The answer to that would likely involve a lot of strange custom 
firmware which would make it hard to provide support.  However if you 
have two of those FX2 parts (and two the CX25840 parts - the video 
digitizer and audio processor) then the whole thing makes a lot more 
sense now.

I'd be willing to bet that you also have a tiny little USB hub on the 
PCB there somewhere and that when you plug in the device, the usbview 
program probably shows a new hub appearing with two instances of this 
device (each corresponding to one of the FX2 microcontrollers).

That last bit about the extra chips present was very helpful actually.  
You just significantly raised the odds that I can get the pvrusb2 driver 
to work with it!
