Thanks for the info. Do you know what voltage the Meade controller was designed to run on? The orion focuser uses a 9V battery and I'm wondering if using the USB 5V is going to make much of a difference.
I found a review of the orion unit on cloudy nights that says my motor only draws 40mA at full speed so I'm assuming this isn't going to put too much strain on the USB port.
