Dumb question of the day: i'm not getting a usb icon anywhere when I plug in the cable to my pc. Going insane. Swiping down I can see all of the standard bluetooth, location services, ect icons, but there is nothing for switching over to file transfer mode. I'm clearly missing something but I have no idea what it is. I've tried powering on while the cable is plugged into the pc, attaching after boot, all the mess. The cable charges just fine so I assume it's not a cable issue (and I have no other cable to test it).
Any thoughts to help a dummy out?
