Hallo Freunde,

ich habe ein dual-usb-interface.

Ich möchte dafür Symlinks anlegen.
ACTION=="add", SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010", ATTRS{bInterfaceNumber}=="00", SYMLINK+="/dev/ttyTS2000-0", GROUP="uucp"
ACTION=="add", SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010", ATTRS{bInterfaceNumber}=="01", SYMLINK+="/dev/ttyTS2000-1", GROUP="uucp"

Leider geht da gar nichts.
Wo liegt mein Denkfehler?

Danke für Eure Mühe

welche kernel version?
Wenn es 4.12+ dann bist du auf folgendes Problem gestoßen: https://github.com/systemd/systemd/issues/8221

Ändere die Regeln so dass statt ACTION=="add" -> ACTION=="add|bind" verwendet wird.

Hallo firefly,

eine kurze Info von mir.

Ich benutze noch Kernel 4.9.77 aus den gentoo-sources.

Dann schau dir mit "udevadm monitor" an was udev macht bzw. welche events abgearbeitet werden, wenn das gerät angeschlossen wird.

Hallo,
bin wieder da.

udevadm monitor

monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

jetzt angestöpselt :

soweit alles okay.

ls -al /dev/ttyUSB*

crw-rw---- 1 root uucp 188, 0 13. Jan 14:57 /dev/ttyUSB0
crw-rw---- 1 root uucp 188, 1 13. Jan 14:57 /dev/ttyUSB1

kein ttyTS2000*

SYMLINK+="ttyTS2000-0 wird nicht erzeugt.

kein Symlink.

Wenn jemand eine Idee hat wäre ich froh.

Füg noch den paramter -p hinzu, dann siehst du auch die properties, dann sollte eventuell klarer werden was bei deiner regel falsch ist

In deiner udevadm info ausgabe fehlen die attribute (die bekommt man mit dem parameter -a angezeigt.
Ich vermute "ATTRS{idVendor}==403" stimmt nicht, da ID_VENDOR=FTDI ist. Eventuell wird dieser wert zu ATTRS{idVendor} konvertiert

EDIT: lies dir auch mal dies durch: https://wiki.archlinux.org/index.php/udev#About_udev_rules

Hallo firefly,

so sieht das jetzt aus:

udevadm monitor -p
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

bin aber trotz lesen noch nicht weiter.

ATTRS{idVendor}=="0403" zu
ATTRS{idVendor}=="FTDI"

hilft auch nicht.

Aber danke für den Tipp.

Okay firefly,
hier die Ausgabe:

udevadm info -qall -a /dev/ttyUSB0

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Unter der Woche ist die Zeit manchmal knapp. Bitte nicht wundern, wenn es mal länger dauert.
