The moral of the storie is: 1. Try to use a short cable. (The one that came with the Book Port is = short enough, and is the preferred cable.) 2. Some long cables do not work with USB 2 ports, even if you are = connecting USB 1.1 devices. (I knew this; unfortunately these recent = issues didn't bring this to mind.) 3. If you are unfortunate enough to require an extension cable, make sure = it is certified for use with USB 2 devices. 4. If things go wrong, try another cable if you have one. Try all of your = USB ports as well. 5. An incompatible cable can produce an error message stating that the USB = device is not recognized or is not functioning properly.

Each of the machines I use has its own USB cable that stays with = =3D that machine, and I routinely use both USB 1 and USB 2 devices on each of = =3D the machines with no problem at all. Now, just today, I did notice that the cable on my main machine at work = =3D was not working with an external hard drive mp3 player device, and it =3D turned out to be the length of the cable that mattered. It was a 6 foot = =3D cable. Oddly enough, I have two of these external hard drive mp3 player = =3D devices, an Archos and a Napster, and it only mattered with the Napster = =3D device. =3D20
