Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

The problem may be quite simple, really. When a USB-cable-connected device gets power, charges up with that power, but is not recognized as a device by the computer, then the Data lines (2 out of the 4 lines in a USB cable) is one or both of them occluded by dirt, broken, cut/snapped, or otherwise defective.


1. take an old (but clean, and dry) toothbrush, and scrub out the USB ports (with the power Off!) and the USB plugs of your USB cable. Then try again.

This problem commonly is caused by dirt, even just a little, or sometimes a slightly loose or slightly strained cable.

Also try a different USB port on the computer, or several of them. USB ports should be all alike, but very often are not in actual fact.

And as the last thing to try, swap out the USB cable for another one. Esp. if it looks strained, was yanked on at any time, or is severely (and/or repetitively) bent at any point.

just received your answer to my question re my Nook and my computer not recognizing my Nook color. I had previously tried each of your suggested fixes to no avail. both new cable and USB hubs (I have 6 or 7 of them) have been changed and I know that the Nook is on my computer as an additional drive but still no luck. Also it appears other Nook Color users have experienced the same problem without determining the solution.

Are you using a USB hub on the line, whether a passive (unpowered) or active (powered, with its own AC Adapter) hub ? if so, try connecting the Nook *directly* to the USB port(s) on your computer. A hub can disable some USB devices... though it really shouldn't, it does.

Hello, my name is Rusty. I'm unclear as to what is happening, you say that it IS showing up on your computer as a drive, correct? Is it just not showing up in your software?
