UVC 1.0?との違い

  • A device that is compliant with UVC 1.1 should set the bcdUVC? flag in the Class-Specific VC Interface to 0x110. In addition, if the optional Processing Unit descriptor exists, a 1.1-compliant device should do the following:
    • Add a bmVideoStandards field to the Processing Unit descriptor.
    • Update the bLength? field in the Processing Unit.
    • Update wTotalLength? to reflect the larger PU size of the Processing Unit.
