Computer and iTunes not detecting iPod Touch 5

I have an iPod Touch 5 running iOS 7. I have a HP Probook 6570b running Windows 8 (yes, everything up to date)

When I connect it, my computer makes the normal noise when you plug anything in. But that's it, nothing else happens. My iPod doesn't show up under Computer, doesn't show up in iTunes, and doesn't charge. I can still charge it with an outlet, but that's it. I tried restarting both devices, and went even reinstalled iTunes, and still it's not being detected.

I noticed about 3 weeks ago it wouldn't notice my iPod, so I unplugged it and plugged it back in. Usually that didn't work, so it required a restart of my computer and then it would see my iPod. Now, it doesn't notice it at all. I've tried different ports, everything. Nothing works. I want to sync some new things on, but I can't. I bought it back in late November, so I still have warrenty if it's needed.

Also, a side note. I've never been able to wifi sync my iPod from my computer. Sometimes it's detected, and sometimes it's not. 99% of the time, it isn't. When I can, the only way is if I press sync on my iPod. When I go on iTunes, it says it can't find it. Yes I've done all the wifi rebooting and all those things. Strange thing is, my iPod Touch 4 on 6.1.2 does it perfectly.
