You keep saying that but you let me quote from your original reply:

It would be useful to use devfs just for USB here. I agree 100% that usbdevfs
should be part of devfs though. I just dont plan to use devfs 8)

This was the first time you said you think usbdevfs should be a part of
devfs, but you also said that devfs would be useful just for USB here.
I took that as you wanted devfs' functionality, but without the rest of
devfs. Am I right or wrong here?

And right here you say you don't want devfs.
However, you say you want usbdevfs to be a part of devfs.
But, you still want it to as good without it?
You have me seriously confused.
You contradicted yourself by saying that you want usbdevfs to be a part
of devfs (exactly what my patch does). However you don't want devfs but
you want all of the existing functionality to be there.
You can't have it like that. If you apply my patch, but don't use devfs,
you can't access devices via userspace.
