MCPC Vendor-Unique Interfaces

The Mobile Computing Promotion Consortium (MCPC) defined a format for interface collections before the Wireless Mobile Communication Device Class (WMCDC) specification provided a format for vendor-unique CDC devices. Therefore, MCPC interface collections do not comply with the WMCDC standard.

However, the USB generic parent driver can enumerate MCPC interface collections if WMCDC is enabled. MCPC interface collections have the following properties.
