I'd try it even on USB just for the screen sharing or even the keyboard/mouse sharing. Here's how I use it at work.
1) If I need to use an app actively, I just share the screen and display it in a window in my Computer. Then use the mouse and keyboard for interaction.
2) If I don't need (or want) the contents of my screen sprawled on my computer screen for all to see or if I just want to do a quick reply, I just use the keyboard/mouse sharing. This is my most used scenario. I keep the phone connected and sitting on a small card holder (perfect, cheap phone base!) in front of me, below my computer screen, and when a message comes through or I need to send a quick one, I just drag the mouse to the edge of the screen, it magically wakes up the phone and the little cursor appears on the phone. Should I need to type something, I use the computer's keyboard. Right/Left click act as tap and back buttons. All without touching the phone, just like having a 'small' extra screen.
