Can I sync Google Nexus and Samsung Galaxy devices using USB?

***** UPDATE: If you are using Windows 7 or Windows 8 on your computer, you can use doubleTwist Sync. More information is available on the Windows 7 & Windows 8 support topic. *****

Many recent Android drives (Google Nexus, Galaxy S3/S4, Note 2/3, etc.) only offer USB MTP mode, which doubleTwist was not designed for as it expects USB Mass Storage (MSC) mode.

You can use AirSync to sync with USB MTP only devices such as the Galaxy Nexus, Nexus 7, Galaxy S3, and Android tablets.

Here are some quickstart guides to AirSync.
