Don, USB (at least through USB 3) uses 4 conductors, 2 for power and 2 for communications. If you look at the flat (USB-A) plug that is the PC end for nearly all USB cables, and picture it as the four fingers of your hand, your pointer and the pinkie are the power conductors, your middle and ring fingers are the communications conductors. All other USB plugs (USB-B, mini, and micro) use the same four conductors and wrap them into a smaller plug, like squishing your four fingers together. It is possible to have damage occur to the wires such that just the power conductors fail, or just the communications conductors fail, just by having too tight of a kink in the cable at some point. Today, we are able to get "Stay Flat" USB cables that strive to avoid that hazard.

My Bamboo has a non replaceable cable; it is molded right into the device. And it has now become moot since I just ordered a new tablet. The prices are not that steep anymore. Thanks for all the help though.

If that one fails, please try a new cable. On my Bamboo at least, it's just a mobile 'phone USB cable, which are readily available (at least here in Oz). A bit of quick work with a file or sharp knife to trim off excess plastic, will allow wider plug mouldings to attach into the recessed socket on my model 470. Andrea.

I bet you just need a new cable My tablet is a 460 so you have a newer model. I have downloaded all new drivers and software and still no go. I believe I will just have to buy a new tablet. Always happens eventually. Thanks to all for you advice. Don On 8/14/14, 5:03 AM, Andrea Coffey wrote: Sorry to come to this after some days' delay.

I have a Wacom Bamboo "Pen and Touch" small, model CTH-470/K, with pen and multi-touch, and it works happily with driver v5.3.3-3 on OSX Mavericks v10.9.4. Drivers here: https://www.wacom.asia/en/tablet-drivers?tid_1=9&tid=49 The same driver is also good for OSX 10.6.8. The driver on the above page may very well get you going. My (now rather old) Wacom Intuos 3, model PTZ-930, with pen only, works with driver v6.3.8-2 on OSX Mavericks v10.9.4. Drivers here: https://www.wacom.asia/en/tablet-drivers?tid_1=17&tid=49
