Hi,

Kann mir jemand sageb welche Syntax ich hier in der udev Rule brauche ?

Habe hier schon einiges probiert:

Zitat:KERNEL=="ttyUSB*", KERNELS=="1-1.4:1.0", NAME="ttyUSB0-XX"
KERNEL=="ttyUSB*", KERNELS=="1-1.2:1.0", NAME="ttyUSB1-test"
#KERNEL=="ttyUSB*", KERNELS=="1-8.1.2", NAME="ttyUSB3" #soll angebeblich funktionieren

Anschliessend müsste ich ja nach dem einstecken ein Gerät ttyUSB0-xx haben ...

Klingt irgendwie nach CH340 Arduino Clone..
Dafür gibts ja eigentlich (wenn man die 0.05€ für nen eeprom spendiert hat..)

iSerial 0

Könnte ohne Seriennr schwierig werden. Physical Address ermitteln vom PCI(e) Port aus über USB Adapter - USB Port ?

Ich glaube KERNEL und KERNALS geht nicht zusammen.

Wie meldet sich das Teil unter lsusb und als welches /dev/.. wird es andemeldet?
Mit
udevadm info --query=all --attribute-walk --name=/dev/...
bekommst Du den udev-tree
In der udev-rule müssten dann keys aus maximal 2 aufeinanderfolgenden Blöcken (Parent/Child) gesucht werden siehe auch http://www.reactivated.net/writing_udev_rules.html
Beispiele sind z.b. In der /etc/udev/rules.d/01-easyvdr-remote.rules oder der /usr/bin/easyvdr-set-ir_keytable

Nicht konstant. Das ist kein devfs..

Genau. Ich will die Arduino Clones anhand des USB Anschlusses fest zu einem Device zuordnen. Also z.B. /dev/Kernreaktor oder so...
8)

Jetzt habe ich fast eine Stunde in den Sand gesetzt mit dem schlauen Einfall ob man nicht mal auf den kaputten (so geliefert) Arduino mit FTDI (echt?) Chip nen Bootloader aufspielen oder notfalls direkt flashen könnte. Der Arduino läuft prächtig. Aber am USB Bus wird nichts enumeriert... Also zurück in die Kiste für "andere Zwecke"

Somit gehts weiter damit...

Zitat:[email protected]:/etc/udev/rules.d# udevadm info --query=all --attribute-walk --name=/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.

Aber erst mal ist "Essen und anderes..." Danke für euer Feedback oben!

Doch noch Frage: Denkt ihr der geänderte Symlink wird überhaupt ohne reboot angelegt wenn man das Gerät neu anstöpselt ?
(Habe gerade das Gegenteil gelesen: OS auf dem Odroid ist Ubuntu 14.04)

Ja, sollte.

So gibt er mal die wichtigsten Infos schön sortiert aus:

Aber mit beiden Varianten legt er mir nur immer das normale Device an: /dev/ttyUSBx

Das wäre immerhin der USB Port als physical Path, wenn du dich also auf einen Port je device festlegst..

Danke so war mein Ansatz ja auch. Gelernt habe ich: Symlink funktioniert theoretisch immer direkt nach dem Anstöpseln.
"Name" dafür wohl nur nach nem Reboot. Das Problem war, dass mir die exakte Syntax unklar war und somit die Tests gestern erfolglos.

In meiner Software kann ich aber auch /dev/seriell/by-path/xxx angeben, somit lass ichs gutsein.
Wenn die Sachen noch produktiver werden, will ich an der Stelle eh nen ARDUINO anderem USB-Seriell-Chip...

Also Danke nochmals!
