As this is the first time we are having this problem, I'd just propose to put just another switch into hid_ignore() for USB_VENDOR_ID_DWAV, and looking at hdev->type there to see whether we should ignore the device or not. If it turns, over time, to be a more general problem for multiple devices, we'll just introduce the more general blacklist matching then.
