I've tried the gp2x wiki but unfortunately the information there isn't very helpful on this. I bought a self-powered ext-usb cable (from http://www.artaylor.co.uk/gp2x/). I tried turning on usbhost/usb storage in the settingsbecause I want it to access a usb pendrive but I'm not sure it it's recognising it, and I can't access it. I bought my gp2x about a month ago and it has firmware v3.0. Am I doing anything wrong?
