Thanks for contacting us, firsttimer. What exactly are you trying to accomplish when you hook your phone up to the computer?

Whaddaya mean "what are you trying to accomplish?" They want it to operate in USB3 mode so it transfers files faster! That would seem like an obvious desire for a phone with a USB3 interface. But they probably also want the phone features to function at the same time instead of being crippled. Just one of those wild and crazy things some nuts want from a flagship device.
firsttimer, it ain't gonna happen. When connected to a computer's USB port, you can either use USB3 mode in airplane mode or you can have a functional phone in USB2 mode.
That's how it appeared to me also. Thanks for the response. First "smartphone". Still scratching my head from time to time. Even first hookup to computer with USB gave some kinks about drivers not installed. Got that resloved. Again thanks.
