There are a few entries in the quirk table that set the device ID with USB_DEVICE() macro while having an extra bInterfaceClass field. But bInterfaceClass field is never checked unless the proper match_flags is set, so those may match incorrectly with all interfaces.
Introduce another macro to match with the vid/pid pair and the audio class interface, and apply it to such entries, so that they can match properly.

I don't know anything about KeithMcMillen Stringport, but all other devices (US122 MKII and E-mu) seems to have Vendor-specific Class.
OK, then it must be with USB_DEVICE_VENDOR_SPEC macro instead although they had .bInterfaceClass = USB_CLASS_AUDIO line wrongly. Could you submit the correction patch, or shall I fix in my side?
Never mind, I prepared a patch by myself. Will submit now.
Thank you! Yes, I think entries in quirks-table were incorrect. Here are some proofs:
