After looking at this some more, and depending on whether you can find out if the vendor driver sends these requests for all devices, I think your original proposal of simply moving this device over to option might be the best solution after all. What is the "lsusb -v" output for this device? Perhaps you can use USB_DEVICE_AND_INTERFACE_INFO so you don't have to blacklist so many interfaces explicitly (e.g. the AUDIO interfaces)?
