HELP please --- I have Win XP Home Edition and HTC Eris (which I love). However, I seem to have lost the ability to mount / unmount the Eris as a USB drive a few days ago. I HAVE transferred files from/to my sd card successfully, HOWEVER I can no longer do so. Regardless of whether I have USB debugging set or not, I NEVER see the "Mount USB" Notification any longer. It just "disappeared". How can I get it back? Thanks!!
