USB Isochronous Transfer Type Support

Hi all,

Recently, I am studying a new feature that need to use camera in UEFI BIOS.
And I found that EDK2 do not support isochronous transfer. (please refer to attached)
But almost all webcams only support isochronous transfer for video streaming.
Does anyone has the experience to implement USB ISO type or use camera in UEFI?

Million thanks.
