Modulo the issue about making a new "devices per driver" counter,
I'd also like to raise the issue of whether this counter shouldn't be
driven entirely by the kernel code binding drivers to devices.

That is, code the USB or PCI layers would increment/decrement
the counter when the binding was successfully achieved.  No
changes to the device drivers needed, but having the kernel
maintain those counters would be safer than doing it in user mode.
