Thanks for your tips, everyone! I got the mount today, got it setup, and tested using USB directly into the side of the mount.
I used Stellarium to slew over to a few stars, and it pointed in the direction it should! It sounded great, too. I can hear a tiny bit of stiction at the very end of slews, but I'm going to try it out in the real world before I make any decisions about that.
One remaining question that I have, especially coming from the CG-5:
The CG-5 has index markers to show you where "home" position is. I always lined those up perfectly before doing my polar alignment (I use SharpCap and my guidescope.) Does it matter that the EQ6R-pro doesn't have these same "built in" physical index markers? Will my polar alignment be off if I don't have the scope mount perfectly placed with counterweights pointed directly down and the DEC axis centered perfectly? I can do my best by sight, but it's not going to be as perfect as the CG-5 was, with its index markers.
Thanks to all of you, I have had such a seamless transition (so far!) I didn't think I'd be this far along after only half a day!
