Does iPod Classic 4 use USB-A to charge?

Apple and MacTracker both indicate that there were only three generations of iPod Classics:

• iPod Classic (September 2007)
• iPod Classic (120 GB) (September 2008)
• iPod Classic (160 GB) (Late 2009)

They had 30-pin dock connectors and charged and synchronized through USB.

Are you perhaps thinking of the iPod (Click Wheel)? Apple says that it is "referred to as the fourth-generation iPod."
