when i try to plug in certain usb connectors, my computer has been saying that i don't have anything in my usb ports, and now when i try it, it says that i don't have it. however, my printer, which is plugged into the usb port on the front, is working fine. also, i've been able to plug in my camera. it seems to just be the memory stick and mp3 player...
anyone out there who can help me?
