Raspberry Pi 4 + knxd + Hager KNX-USB-Interface - Kommunikation wird nicht aufgebaut

[benten]

Hey,

bin blutiger Anfänger mit KNX und knxd.
Versuche gerade einen Raspberry Pi 4 aufzusetzten, damit ich mit einem Hager KNX-UBX Interface kommunizieren kann.

knxd Config sieht wie folgt aus:

KNXD_OPTS="-f9 -t1023 -e 0.0.1 -E 0.0.2:8 -u /tmp/eib -b usb:"

nach einem restart des knxd kam dieser Fehler:

Jan 17 15:45:45 raspberrypi systemd[1]: Starting KNX Daemon...
Jan 17 15:45:45 raspberrypi knxd[18827]: libusb: error [get_usbfs_fd] libusb couldn't open USB device /dev/bus/usb/001/003, errno=13
Jan 17 15:45:45 raspberrypi knxd[18827]: libusb: error [get_usbfs_fd] libusb requires write access to USB device nodes
Jan 17 15:45:45 raspberrypi systemd[1]: Started KNX Daemon.

Daraufhin habe ich etwas gegoogelt und diese Lösung gefunden:

"sudo chmod a+w /dev/bus/usb/001/003"

Soweit ich sagen kann hat das geklappt.

Und jetzt sieht der LOG so aus:

Kann sich da jemand einen Rheim drauß machen?

Vielen Dank im Vorraus

diese Fehlermeldung ist der "Wendepunkt"

diese Fehlermeldung ist der "Wendepunkt"

Bedeutet also, knxd kann keine Verbindung mit dem Interface aufbauen.
Und die Berechtigung, welche ich dem USB Port zugewiesen hab, hat das Problem nur verschleiert.

Habe jetzt den Raspberry neu gebooted und den USB Port gewechselt, andem das Interface hängt.

Hättest du noch eine ander Idee knxPaul?

Nein, das ist eine seit Jahren bekannte zusätzliche Herausforderung. Mit dem chmod bist Du ein Stück weiter gekommen.
Nun versucht der knxd über USB eine Verbindung zum Hager KNX-UBX Interface aufzubauen, sendet viermal das Gleiche und erhält keine Antwort. So weit kann ich das log in #1 interpretieren.

Also zufällig gab es im Oberenstock auch ein Hager Interface.

Habe kurzerhand des Raspberry genommen und dort angeschlossen.

Hat direkt funktioniert!

Anscheinend hat die Schnittstelle einen Macken. Dummerweise gibt es an dieser keine LED, wo anzeigt ob eine Bus Kommunikation statt findet.
