The Sound Devices MixPre-D audio card suffers from the same defect as the Sound Devices USBPre2: an endpoint shared between a normal audio interface and a vendor-specific interface, in violation of the USB spec. Since the USB core now treats duplicated endpoints as bugs and ignores them, the audio endpoint isn't available and the card can't be used for audio capture. Along the same lines as commit bdd1b147b802 ("USB: quirks: blacklist duplicate ep on Sound Devices USBPre2"), this patch adds a quirks entry saying to ignore ep5in for interface 1, leaving it available for use with standard audio interface 2.
