I have been trying to charge my Evo via USB to no avail lately. Whenever I plug in my Evo, I select Charge Only (or if I do nothing, it selects Charge Only automatically. My Evo then continues to charge for about 15 seconds before my screen lights up and it stops. I checked to make sure my computer wasn't automatically mounting the USB drive or anything like that. If I turn off my Evo it charges from the USB fine. If I charge it from the wall it charges fine. I have tried different USB ports and my USB hub. I've tried resetting the Evo and my PC several times but nothing does the trick. This wasn't an issue last night and the only thing that has changed is that I installed the new HTC update. Edit: If I select "use as disk drive" the phone charges fine. It seems that the "Just Charge" option is broken.
