Philippe,
Could this be merged for 8.2 as it fixes USB on the amigaone machine?
This would be useful as usb-storage is the simplest way to share data
with the host with these machines.
This is a slight change from v2 adding more comments and improving
commit messages and clean things a bit but otherwise should be the
same as previous versions. Even v1 worked the same as this one and v2,
the additional check to avoid stuck bits is just paranoia, it does not
happen in practice as IRQ mappings are quite static, they are set once
at boot and don't change afterwards.
