Hi !
I agree with you on all the points, but then, I cannot do what I want, as this
job is for a customer.

That's what the customer is actually doing, and what is found at the end of the
documentation: Documentation/usb/usb-serial.txt
Generic Serial driver
insmod usbserial vendor=0x#### product=0x####

That's what my driver looks like, whith only probe and disconnect functions for
some stuff.

Of course :)
But this is for a customer with very particular needs, not for the mainstream
kernel.

Partly, but the customer does not want udev.
And I do not see which part in the usb-serial code makes device connected to
port 18 on the machine be ttyUSB18 if it's the first connected device.
It would be ttyUSB0. no?
Maybe I'm missing something, I'm not accustomed to udev, just told the client
that we should have a look at it for it may solve some parts of his problem and
he told me he does not want udev, so I did not look further.

This would be no problem,
If you want I can send it all to you in the end, just ask me.
This is GPL code isn't it ?

This is a request from the customer.

Have fun,
