[SOLVED] Serial port adapter

[grumpos]

Hi all,
I hope this is not the wrong section ...

I managed to run an usb-rs232 adpater on a mint 13 distro with:

 sudo modprobe ftdi_sio vendor=0x05d1 product=0x5001
sudo chmod o+rw /dev/ttyUSB0 
  

But I've to do this everytime the pc starts.
For the permissions on ttyUSB* I found a solution adding my account to dialout group.
But how run modprobe every time I plugin the adapter?

The manufactor guide says to copy a .rules file to

/etc/udev/rules.d

but it doesn't work.
This is the file (99-bbftdisio.rules):

  *********** Brainboxes USB2Serial range *********************
#
# US-101 - USB 1xRS232
SYSFS{idProduct}=="1011", SYSFS{idVendor}=="05d1", RUN+="/sbin/modprobe -q ftdi_sio product=0x1011 vendor=0x05d1"
# US-324 - USB 1xRS422/485 1Mbaud
SYSFS{idProduct}=="1013", SYSFS{idVendor}=="05d1", RUN+="/sbin/modprobe -q ftdi_sio product=0x1013 vendor=0x05d1"
# US_357 - USB 1xRS232/422/485
SYSFS{idProduct}=="7001", SYSFS{idVendor}=="05d1", RUN+="/sbin/modprobe -q ftdi_sio product=0x7001 vendor=0x05d1"
# US-257 - USB 2xRS232 1Mbaud
SYSFS{idProduct}=="5001", SYSFS{idVendor}=="05d1", RUN+="/sbin/modprobe -q ftdi_sio product=0x5001 vendor=0x05d1"
# US-313 - USB 2xRS422/485 1Mbaud
SYSFS{idProduct}=="6001", SYSFS{idVendor}=="05d1", RUN+="/sbin/modprobe -q ftdi_sio product=0x6001 vendor=0x05d1" 
  

What I've to do to load ftdi_sio when the adapter is plugged in?

Thanks

Hi,

Have you looked at the output of udevadm info?

First, with the device plugged in, find your tty device in /sys:

find /sys/devices/ -name ttyUSB0

Then run udevadm info on the path that command returns, e.g.:

udevadm info --query=all --path=/sys/devices/pnp0/00\:07/tty/ttyUSB0

also, try using udevadm test, while it is plugged in, e.g.:

udevadm test /dev/ttyS0

the output of that command should show you any errors in your rules file, and also show you other rules that are getting processed.

hi atreyu,
thanks for your help

this is the output of udevadm test /dev/ttyS0

add_rule: invalid rule '/etc/udev/rules.d/70-bbftdisio.rules:66'
add_rule: unknown key 'SYSFS{idProduct}' in /etc/udev/rules.d/70-bbftdisio.rules

Each rule give the same error. Some advice?

[atreyu]

Can you post that file (/etc/udev/rules.d/70-bbftdisio.rules) in its entirety?

FYI, the :66 at the end of the line means that udev is detecting a syntax problem on line 66 of that file. Also, clearly, your version of udev does not honor the SYSFS{idProduct} key either. That has aggravated me it the past, too.

[grumpos]

I posted a piece of .rules on first post (all the rules are the same, only vendor and product change)

However, I found that SYSFS, BUS and ID keys have been removed from udev.
So, I changed SYSFS with ATTR key and now the rule works and the adapter is attached to ttyUSB0 when it is plugged in.

Thanks for your help

Sweet, glad it's sorted. I'll mark this thread as Solved for you.
