Detailed Description

Type define for a standard interface association descriptor.

This descriptor has been added as a suppliment to the USB2.0 standard, in the ECN located at http://www.usb.org/developers/docs/InterfaceAssociationDescriptor_ecn.pdf. It allows compound devices with multiple interfaces related to the same function to have the multiple interfaces bound together at the point of enumeration, loading one generic driver for all the interfaces in the single function. Read the ECN for more information.

Note:
The non-standard structure element names are documented here - see the StdDescriptors.h file documentation for more information on the two descriptor naming schemes. If the USE_NONSTANDARD_DESCRIPTOR_NAMES token is not set, this structure contains elements with names identical to those listed in the USB standard.
