This isn't a tenable position.  Sometimes a device looks bad because the
host state for it has gone insane.  At that point, the only safe action
is a reset of the host to sane state.

I could be persuaded that you should never do the transport equivalent
of a bus reset (on non-SPI transports, at least), which is actually hard
to do on some of the modern transports, but I don't think you can get
away without having a host reset in the eh arsenal.
