Thanks for your reply.
If I use directly the ftdi_sio driver, I can't read anything.
some details :
$ dmesg

Nothing appears !
If I add this device id "by hand", I can't set the parameters, but I can
read something (not usable unfortunately)

instead of 1200 cs7 parenb
Since this device is already supported by the driver, I will resume my
tests using the ftdi_sio driver directly.
If you have any solutions, I would be interested
Thanks

Hi !
I try to use a usb-serial converter and i can't set the baud rate (and other
stuff) on the ttyUSB0.
The converter can be see on this page (Version USB : 20.00 €) :

There is some data from my system (raspberry pi b+, raspbian) :

If you need other data, ask me.
(and sorry for my english.. I'm french so...)
This device is already supported by the ftdi_sio driver, there is no
need to provide module options to the generic usb serial driver for this
id.
Have you tried just using the ftdi_sio driver directly? Why are you
adding this device id "by hand"?
thanks,
greg k-h
