IMO, it'll be better to do the swap on lower level - the uep(4) kernel
driver. I can provide a patch for you to test.

It might be even possible to autodetect device and autotune this.

Hans, can you provide any advice on adding USB quirck. We've got
different touchscreens that are identified and attached by uep(4),
but they behave differently. Is there a way to fetch additional
information from a device (vendor, revision, etc...)?
