Hey, just started learning the ropes for android and ran across this issue yesterday. Does the phone that you can connect to your computer require the phone to have an SD card in it for it to work as a dev phone? Meaning, there is currently no SD card in the device. So when I connect device to the computer via USB. Windows (XP) will recognize that the phone is connected but in the file tree, clicking the plus button next to E:drive shows an empty space. I will also receive the warning "Please insert disk into drive E:" when trying to open drive E: Btw, phone is an older HTC Evo. I reset to factory defaults with no SD card installed. So there is space on the phone, I'm also just wondering if there is a way to bypass needing an SD card and just use the phone's memory?
