I connect my zune cable to my zune but there is nothing happening. No charging, no connecting, the computer doesn't even recognize that a device has been plugged in. I have already messed around with the USB ports and made sure they were clean as well as reinstalled them under properties in my computer. Could it just be that the cord is bad? The zune cable works when I plug it into the wall charger just not on the computer. Help please. Thanks

You might need to reinstall the drivers, or update your USB port drivers.
A nice zune troubleshooting guide on this is available on fixing zune device errors.

Hope it helps.

Did you download the Zune software?

The Zune website has the Zune software which must be downloaded for your computer to communicate with your Zune.

And when you connect your Zune to your computer it should begin charging (as I'm assuming this is a new device).

If you have already installed the software I would assume the low battery was slowing the communication between your Zune and your computer.

If you Zune is fully charged and the software is fully installed try plugging the USB cable into a different port. Sometimes the Zune and the connector USB isn't automatically sensed on certain ports and certain moments.

I would first allow the Zune to completely charge (the battery symbol should be full and green[i believe--it's been a while since I first got mine]).

I would then unplug the device and restart the computer. Once your computer has completely rebooted connect the device to the computer and see if it detects the device. It should work. Also you might try another USB port.

maybe the USB is rusty or dirty...it also happens to me

I found this on the Zune technical support (if this does help, be sure to rate my solution please):
Your Zune device is not detected by your computer or the Zune software

SYMPTOMS
When you try to use Zune Software, you experience one or more of the following symptoms:
• The Zune device is not detected by the computer. 
• The Zune device is not detected by Zune Software. In this case, when you pause on the device icon in the lower-left corner, you receive the following error message:
No Zune device connected 
• If you restored the Zune device software, the following messages are displayed on the Zune device:
Connect Zune to your PC
On your PC, open the Zune software and restore the Zune device firmware 

THINGS TO TRY
To resolve this issue, follow these steps:1. Update the Zune software on the computer. To do this, click settings, click software, click GENERAL, and then click CHECK FOR UPDATES.

If the issue is still not resolved, go to the next step. 
2. Restart the Zune device. 

To do this, follow these steps: a. Set the Hold switch to the unlocked position. 
b. Press and hold the Back button as you press the top of the Zune pad. 
When the Zune device begins to restart, release the buttons.

If the issue is still not resolved, go to the next step. 
4. Connect the Zune device to a different USB port on the computer. Use a USB port on the back of the computer. Do not use a USB hub. 

If the issue is still not resolved, go to the next step. 
5. When you connect the Zune Sync Cable to the connector port of the Zune device, make sure that both ends of the sync cable click into position. Additionally, make sure that the sync cable is not connected to the device at an angle. 
6. Connect only one Zune device at a time. If you already have a Zune device connected to the computer, any other Zune that you try to connect will not be detected by the Zune software. Disconnect any additional Zune devices, and then try to connect again.

If the issue is still not resolved, go to the next step. 
7. If a full-screen battery image appears when you connect the device to the computer, you must let the device charge for several minutes before the device will start and be detected by the computer.

11. Try using a different Zune Sync Cable.

It sounds like you guys might be suffering from the Infamous zune new year bug. Let your Zune completely die (leave it for a few days if you have to). After doing this plug it into a computer or wall out let to charge. Leave it to charge for at least an hour. Come back and unpluge the zune and reconnect it to a different usb port if possible. Let it continue to charge.

Letting it die should fix the freeze and swapping ports during the charge will help the computer detect the zune as when their batteries are 100% dead they do not have enough power to say that they are there.

Hopefully this will help out one or two of you.

Try this....
Reset Zune: Press and hold the back button while pressing up on the control pad.
Connect Zune to a power source: If the Zune device is in sleep mode, this action will wake the Zune device and turn it on. If the battery does not have a charge, you may have to wait several minutes for the Zune device to turn on.

Also, make sure that the hold button on top of your zune is turned to the off position.

Hope this helps

ALL YOUR BASE BELONG TO US - is a video that must have been loaded on the Zune previously.

if all else fails...

If you connected the ZUNE to your computer before installing the software the computer may have installed it as a different device.

Go to Control Panel - then System - Device Manager. Plug in ZUNE player and see if any new devices show as being connected. BE CAREFUL IN DEVICE MANAGER THOUGH, IF YOU UNINSTALL THE WRONG ITEM, IT COULD MESS YOUR COMPUTER UP.

If this works rate it a FIX-YA!

Power sources that are supported loadTOCNode(2, 'moreinformation'); To charge the battery in your Zune device, you must connect the Zune device to one of the following supported power sources:

• A computer’s USB port that you can connect to by using a Zune Sync Cable.
• A Zune AC Adapter that you can connect to by using a Zune Sync Cable. Note The Zune AC Adapter is sold separately.
• A Zune Car Charger or a Zune FM Transmitter/Charger. Note These items are sold separately.
• An Xbox 360 console's USB port that you can connect to by using a Zune Sync Cable.
• A “Designed for Zune” mobile battery pack

I figured out the solution by just getting upset.
Hold the Back arrow (<-) and Up on the touch pad and it will restart the Zune. This works for the 8gig and 80gig Zune.

To reset the zune you must press and hold the back button and the top part of the zune pad. Other parts of the zune pad will not work.

When plugging the zune into your PC does the PC detect it (device manager -> portable devices). You should hear the ding sound of hardware connecting.

If it is connecting to the PC and is not detected by the software than it is likely a permissions problem. Right click the software icon and choose run as administrator.

If it is not detected by the PC than check your usb cable and make sure your zune is charged and not frozen.
