Re: disable ldusb

The problem is that I want to develop my own driver because i want it
could be the more generic as possible, so i need iso transfers and
libusb don't have it, also i don't want ldusb because only works for
int transfers and i also need that it could be capable to give to the
user (via ioctls) all the descriptors.
It is very important that the driver could use all the transfers and
give the user all the descriptors info, because it is been develop for
a generic IOBOARD similar to the picdem but different in a lot of
concepts.
Please if you could explain me more about the free VID/PID that
microchip give, i only know the vid 0x04d8 and pid 0x000c.

Andres
So the main problem is how to disable automatic load of ldusb in the kernel.
