usb timing error during ipad restore

With a 1st generation iPad I first had problems with the "not charging" message when connected to a power source then my PC wouldn't recognise it. So through these communitiy bulletin boards I went through resetting procedures and finally attemtped a restore which has come up against a 1604 error, possibly USB timing problems. Now it is frozen on the "connect to iTunes" message on the screen and any number of attempts to restore come up with the same error.

Any ideas?

iPad, iOS 5.1.1

Have you tried a different cord? Different port on the computer? Different computer altogether?

From the 2nd link below.

Error 1604

This error is often related to USB timing. Try changing USB ports, using a different dock connector to USB cable, and other available USB troubleshooting steps (troubleshooting USB connections. If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.

If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:

Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode, put it into Recovery Mode.
Restore and wait for the error.
When prompted, click OK.
Close and reopen iTunes while the device remains connected.
The device should now be recognized in Recovery Mode again.
Try to restore again.

If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection.

Yes I have tried different cords and differwent USB ports. Only one of the 3 works at all and it has a different colour mini board inside it than the others. When the iPad was working porperly I don't know that any of the 3 ports didn't work.. I have purchased a few cords over time off eBay but I'm now only using the original white apple cords I got with my iphone and ipad although I don't know which is which any more. I never use a dock although my wife does when she syncs her iPhone. When you say a different computer altogether, it obvously needs iTunes but does it need to know my iPad. Could a new Mac work?

When you say the device might need a service, what does that actually mean? I have thought that the iPad terminals might be dirty or something because it stopped being recognised by the PC as a hard drive and also iTunes. But after attempting a recovery it is now at least being recognised by iTunes in as much as prompting a message in iTunes that it needs restoring. If that makes sense.
