In the status screen of Activesync it says...

Inbox: Attention Requried
Resolve Items

I try to resolve them and a window pops up

Title of Window: Information Type Not Synchronized

Items of one or more information types cannot be synchronized. Disconnect and reconnect your device.

To view all error messages and dialog boxes that require your input, you must connect to this computer via infrared or serial/USB cable.

I do not know what this means. I'm syncing through USB.

Sounds like you have some unresolved items. Take a look at this page as there is some help information that may help you.
