Is there any objection to the remover patch I submitted a while ago
to the hotplug and usb-devel lists? It seems to help my design of
applications that use USB devices, so I would like to get it integrated
into the main hotplug repository. If there are specific objections,
I can address them.
If they don't get integrated, then I'll choose to package and distribute
my patch on my own, along with my application, at least until there is
an adequate equivilent.
(Or until I find a better way.)
I've attached a fresh copy, as the patch is very small.
