This sounds like a huge waste of time - rather than abandoning something
as immensely useful as hotplug, just get the bug in the USB driver
fixed!  AFAICT all the people having this problem are using really old
kernels anyway.  It's idiotic to abandon hotplug just because you don't
want to upgrade your kernel to fix a known bug.
