Well if it's of any consolation, I'm having all the same issues. My EQ6-R PRO mount has a USB port, which should, according to FLO and SKY-WATCHER, be able to control the mount. After many many tutorial videos, none actually using the usb lead, I got it to move but stopped after a minute.
I've noticed a lot of 'help' on here starts very in-depth, quoting lead types and plugs and what not. For a complete beginner that is just really off putting. People should remember that there was a time when you didn't know anything and what beginners need is slow precise instructions, call it an idiot guide if you must.
