Running a non-rooted 2.2 Desire so once your phone is mounted as a USB drive(mass storage), how do you exit ? 1. Do you reallly need to ? 2. If you do, how are you doing it ? While i would like to use the extended controls widget, when i do try to turn the USB button off, it says "Mass storage deactivated", and promptly after that " Enabling Mass storage". what am i missing here ?
