Sorry, my hands don't keep up with my brain - that's almost another
speculative execution vulnerability!

What I meant to say is:

applying patches 1 and 2 breaks USB

but

the solution here would be to apply patch 1 and patch 3, followed
by patch 2 (unless it will make the USB defer, IDK, it's probably
easier to just test than to dive deep into the code)

with Bjorn taking both subsystems, we can make that work I think
