Erin,
I'm not the OP,
when I plug my Tablet (not phone) (ICS 4.0.4) into my Win7 PC... It does not show up in Windows Explorer. The USB eject button (in the lower right tray) doesn't appear unless I have another USB device plugged into the PC. Under the tablets Settings>Developer Options>USB debugging is checked. Now with a USB thumb drive plugged into the PC, the Eject USB will list the thumb drive and Eject Android with Removable Disks J: and K: But Windows Explorer still doesn't show anything other than the C: drive, the thumb drive and network. i.e. no J: or K: Eclipse was able to load the Hello World app to the tablet.
Also, what do I need to do to "use" the SD card I've plugged in? Are there directories or files I need to write on it (with a PC) before I plug it into the Android?
Thanks in Advance
TheZuke
