actually you want to use USB_VENDOR_AND_INTERFACE_INFO like we do for all the other Broadcom based devices. So that all HTC devices that have the Broadcom ff:01:01 interface description are covered.
And if you can add /sys/kernel/debug/usb/devices to have to the full descriptors, that would be great. If this works with the BTUSB_BCM_PATCHRAM quirk, then there is also some extra debug info in dmesg that you might want to include.

Marcel
