(adsbygoogle = window.adsbygoogle || []).push({}); When I plug my HTC EVO in it won't let me choose whether i want it to charge, sync, usb, or tether. It just charges any suggestions ?

I rarely plugged my phone into my computer, but if you go to 'My Computer' you can open it up from there.

On your phone go to settings -> SD card and phone settings -> from here, every phone will vary, but you should be able to manage your way...
