If Sharepod is asking you to connect your device after it's already connected to your computer with its USB cable, first make sure that you have iTunes open and that your iPhone, iPad, or iPod is appearing in iTunes. If it is showing in iTunes but not in Sharepod, you should just need to unplug and reconnect your device. If that doesn't help, try closing and reopening Sharepod.
If you are running iOS 7 or 8 on your iPhone, iPad, or iPod Touch, be sure to tap on "Trust this computer" on your device when plugging it into your Mac or PC.
If you have a regular iPod such as a Classic, Nano, or Shuffle, it's recommended to check the box to "Enable Disk Use" in iTunes on the Summary tab for it and click on Apply. That setting will help your iPod stay connected in Sharepod and iTunes.
If the above steps didn't help, please try the ones below:
1.) Close Sharepod and iTunes.
2.) Unplug your device from your computer.
3.) Reopen Sharepod 1st and then iTunes 2nd and plug your device back in.
4.) Wait for your device to appear as connected in iTunes.
5.) Check for it in Sharepod.
YOUR DEVICE WON'T EVEN CONNECT IN iTUNES
If your iPhone, iPod, or iPad isn't even showing up in iTunes, you'll need to figure that out first since an iDevice should be appearing in iTunes when it's plugged in with its USB cable. I would first just try restarting your computer. If a restart doesn't help, you'll find some useful troubleshooting steps in the AppleCare articles below. Just click on one to be taken to the article:
iPod Classic, Nano, Shuffle, and any other regular iPod:
Mac: iPod not recognized in iTunes and Mac desktop
PC: iPod not recognized in My Computer and in iTunes for Windows
iPhone, iPad, and iPod Touch:
Mac: iOS: Device not recognized in iTunes for Mac OS X
PC: iOS: Device not recognized in iTunes for Windows
Once you get your device to appear in iTunes, you should then see it connected in Sharepod too unless iTunes is showing an error about your device such as "unable to start the iPhone listener process".
