Those are not ordinary processes.  Rather they are kernel threads (or
some such description) -- along the same lines as the vmdaemon,
swapper or syncer threads.

In order to get rid of them, you'ld have to compile a custom kernel
with all of the usb support ripped out *and* you'ld have to take steps
to prevent the kernel autoloading a usb.ko kernel module on boot up.

If you have inadvertently loaded a usb kld module -- use kldstat(8) to
see if that is the case -- then you should be able to unload it with
kldunload(8), so long as it's not actually busy doing stuff.

On the whole though, I wouldn't bother too much about those usb kernel
thread things.  They're generally harmless and they don't have any
impact on the rest of the system if there are no USB peripherals in
use.

	Cheers,
