Seemly, this protocol is only used in UsbDxeBus module. If= so, this protocol can be defined as the internal protocol in UsbDxeBus mod= ule.

USB Interface Association = is a group of UsbIo that implement a USB function. UEFI device driver manag= es multiple UsbIo instances. Examples of such devices are: USB camera, USB = serial, USB network, etc.

Current approach for supporting these devices is to = respond on UsbIo installation and analyze if the current UsbIo belongs to t= he USB association. This algorithm is based on assumptions that may not be = correct for different device configurations. Having USB association protoco= l that reports its associates (UsbIo) simplifies the USB device driver.

 =

Fo= r the USB configurations that implement USB association the UsbDxeBus drive= r will:

  • create USB association device<= /li>
  • install device path<= o:p>
  • in= stall USB association IO protocol

Request to create edk2-staging/usb_iad bran= ch, patch is attached.
