The animal I've been looking for (for a version 1 MX-3000) is a USB 4-pin Male (A type) to mini 4-pin Male (A type).
Ran down to Fry's yesterday and of course, had to look in multiple locations, and found a USB/1394 kit with about every connection you could think of in it.
Walked over to the computer section, whipped out my laptop and MX-3000 and fired it up. Works like a champ - downloaded rc file to the remote - should've seen the look on the salesmen's faces! Been working on a more "leopardish" version of Brucks' mac theme interface. Created quite a stir. I'll post some screens as soon as I'm finished.
At any rate, I paid about $25 for an entire kit. Did some research this morning (now that I know what connector it is) and came up with lower cost, or more readily available, solutions.
Belkin model # F3X1724 is a kit similar to the no-name brand I bought. Also, there are multiple links to this cable on the net ranging in price from $2.00 to $15. And, of course, the egg has it for about $1.49 (N82E16812116127). Who would have known. Don't let the pic on the site fool you - just make sure you've got the mini 4-pin male "A".
Going to give URC support a call in the morning and let them know that a solution is, relatively, readily available as they didn't even know what connector was being used.
Thanks for all the posts back and the assistance, gotta get back to work.

P.S.: Bad idea going into Fry's the week after xmas! Ended up leaving with a new mobo/duo-core proc/4 Gig ram/couple HDDs and some new Pelican protection for gear. Oh well..., can always make more money!
