The more basic arguments that prevailed at the last time such an
"eject" command was being considered for inclusion into usb-storage
were:

1. Userspace can obviously react a lot quicker than kernel space to
new or changed devices popping up.

2. Userspace works with older kernels immediately.

Neither am I. But the number of known mode-switching USB devices is
now at around 50. New ones are arriving by the month or even week.

A decision to handle *all of them* in usb-storage would lead to the
disadvantages pointed out.

A decision to handle just *some of them* can hardly be made
plausible if there are no immediate technical reasons.

Oh, and in most cases (including your suggestion) there *are*
already two drivers necessary to make these devices work,
independent of where the switching is happening ...
