have you installed the USB drivers? latest drivers for ascom? Ive had the gemini 2 for a year now so if you need some help just send me a msg. December 2011 is the latest firmware. You can download a program which helps with the upgrade of the firmware. It really is great.
http://www.gemini-2.com/ is a really helpful site. You can download the installer from that website.

I highly recommend you master the gemini 2 hand controller before you let the computer do all the slewing. You need to do your star alignments first. You must do both an eastern and western model for goto.
