Help! I have a new sony digital recorder but the PC says Code 31, windows cannot load drivers. But when I plug an older recorder (same brand) which I used to plug in the same port, it is detected. I try updating the driver, but it says updated already. Still won't detect new device. please help! I have Windows 7 desktop.
