SYMPTOMS

On a Windows Vista-based computer, when you connect a Media Transfer Protocol-capable (MTP-capable) device, Windows Media Player cannot synchronize media to the device.

CAUSE

Based on the MTP specification, all class-specific requests are sent to targeting interface 0. This can be a problem for composite USB devices that send class-specific requests to the matching class interface. The hotfix that is described in the "Resolution" section assigns the correct interface number for MTP requests.
