to knxd

Hello,

I'm new with knxd. I already installed it on Ubuntu 18.04 together with openHAB.

knxd runs on Ubuntu without any problem but ...

I get no connection to the USB.

If I follow the manual on Github I get the following answers:

~$ udevadm info --attribute-walk /sys/bus/usb/drivers/cdc_acm/*/tty/ttyACM0
Unknown device, absolute path in /dev/ or /sys expected.

But if I use:

~$lsusb
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 003: ID 145c:1330

I see the USB device.

Also if I try:

~$dmesg | grep usb

I get:

[ 1552.497970] usb 6-1: USB disconnect, device number 2
[ 1558.393872] usb 6-1: new full-speed USB device number 3 using uhci_hcd
[ 1558.604896] usb 6-1: New USB device found, idVendor=145c, idProduct=1330
[ 1558.604902] usb 6-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 1558.604906] usb 6-1: Product: KNX-USB Interface (Flush mounted)
[ 1558.604909] usb 6-1: Manufacturer: Busch-Jaeger Elektro GmbH
[ 1558.611850] hid-generic 0003:145C:1330.0004: hiddev0,hidraw0: USB HID v1.01 Device [Busch-Jaeger Elektro GmbH KNX-USB Interface (Flush mounted)] on usb-0000:00:1d.0-1/input0

So, I think the device is connected. Or I'm wrong?

The main question is now: What I have to enter in to the /etc/udev/rules.d/70-knxd.rules?

At the moment the file looks like this:

ACTION=="add", SUBSYSTEM=="tty", ATTRS{idVendor}=="145c", ATTRS{idProduct}=="1330", KERNELS=="6-1:1.0", SYMLINK+=$LINK+="knx1", OWNER="knxd"

Is it possible to connect this device to knxd?

Thank you for your help!

Robert

to knxd

This is not a TTY device, it's a USB-HCI device and the messages you posted say so quite clearly. I have no idea why you think it's controlled by the cdc_acm driver. Care to enllighten us?

This device already is in knxd's udev ruleset. Just use "-b usb:" for knxd to talk to it.

Thank you for your quick answer.

I have not so many skulls with USB and Linux ... I just follow the howto's ...

I used this howto: https://wiki.fhem.de/wiki/Knxd

I edit /etc/default/knxd like the howto:

START_KNXD=YES

and

DAEMON_ARGS="-e 0.0.1 -E 0.0.2:8 -u /run/knx -u /var/run/knx -i -b usb:"

Is this correct?

Do I have add something after "usb:"?

I'm really sorry, but I have only limited knowledge.

to Robert Schrödel, knxd

No, nothing special needed, "usb:" should be enough.
Still, I wont stop to tell: keep your fingers off USB-IF if you don't
want to learn about trouble & pain - it just doesnt work..
