ttyUSB not showing up, modprobe unknown parameter 'vendor' & 'product'

Hello,

I have tried this on Ubuntu 12.04.5 and 14.04

I have one evice that I connect with usb adapter. The instruction states that I should do this:

Code:

rmmod ftdi_sio
modprobe ftdi_sio vendor=0x0403 product=0xf248

this should create ttyUSB0, but there is no ttyUSB0 in /dev/

this is step by step for 14.04

so step by step:

1. connect usb

dmesg:

Code:

[  273.398522] usb 2-2.2: new full-speed USB device number 5 using uhci_hcd
[  273.582354] usb 2-2.2: New USB device found, idVendor=0403, idProduct=f248

help please


EDIT: here is something that I fond, but this solution didnt work.

From kernel 3.12, the ftdi-sio module no longer accepts the "vendor" and "product" parameters (commit link). I think it was assumed that this was a debugging feature
that should not be used by end users, and so the change was not at all publicised.

The new way to add a new VID/PID pair for the ftdi-sio driver is to write them both, one after the other, to /sys/bus/usb-serial/drivers/ftdi_sio/new_id:

# modprobe ftdi-sio

# echo 0403 f248 > /sys/bus/usb-serial/drivers/ftdi_sio/new_id

EDIT2: I also updated the repo to include lateset repo, and I deleted usb-serial and install the latest

Ok it worked after all. What I had to do is:

Code:

sudo chmod 666 /sys/bus/usb-serial/drivers/ftdi_sio/new_id
nano /sys/bus/usb-serial/drivers/ftdi_sio/new_id

type my vendor and product id and save file with CTRL+x > yes

Code:

0304 f248

plug and unplug device
