because a usb device was drawing too much power from your computer one or more of your usb devices have been disabled
Last time I connected to a pc it crashed.
So I think the cables and card are fine.
I don't want to take the camera apart so I think I'll stick with the card reader. Thanks for the ideas.
I agree with Geru2000, that it may very well be the cable. USB ports provide up to 1 amp of 5v dc power to the attached devices. A short in either the cable or the camera could easily cause the device to draw more than 1 amp. That message seems to be the software equivalent of blowing a fuse or tripping a circuit breaker.
Try connecting just the cable, without the camera attached. If it is a short in the cable, you should still get the message. If that happens, get a new cable.
OTOH, it is my opinion that using a card reader is preferable in almost every way. I really can't think of any way that the USB cable attachment beats a card reader, except in the case that your computer doesn't HAVE a card reader. In that case, get one. They're cheap. Just make sure that it supports SDHC cards. Some support only SD cards up to 2GB.
EDIT: I just thought of a reason: you can only do tethered shooting via the USB cable. That's sort of the definition of tethered shooting, now, isn't it?
