How can I add new udev rules for a ftdi-sio device?

Question

I am trying to add the following file to /etc/udev/rules.d:

ACTION=="add", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="FAC6", RUN+="/sbin/modprobe ftdi_sio" RUN+="/bin/sh -c 'echo 0403 FAC6 > /sys/bus/usb-serial/drivers/ftdi_sio/new_id'"

and then I write in terminal sudo service udev restart to reload the new rule.

I unpluged and pluged again the device and it doesn't recognize it as FTDI-SIO device. What must I do?

The output when I plug it and execute on terminal dmesg is:

[ 1469.235761] usb 1-3: new full-speed USB device number 13 using xhci_hcd
[ 1469.392269] usb 1-3: New USB device found, idVendor=0403, idProduct=fac6
[ 1469.392278] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 1469.392284] usb 1-3: Product: USB2-F-7001 CAN-Plus Adapter
[ 1469.392289] usb 1-3: Manufacturer: EasySync

I am running Ubuntu 16.04 LTS and the device is USB2-F-7001.

Best regards. Alessandro

Your rule syntax looks correct to me, I've just successfully done something very similar with identical syntax and just a different product_id.

what's the name of your rules file?

It should be <number>-<description>.rules

eg /etc/udev/rules.d/99-usb-can.rules
