Thank you for your effort.
Given its ancestry, I suppose this code is GPL? If so, we can't merge it
upstream easily, as libpayload is BSD.

Interrupt transfers are important for keyboard support.
Isochronous transfers aren't supported by the stack so far (except if
you added it), but I fail to see a need for it in firmware anyway.
