Ich habe auch dieses mal gelöste Problem:
Der Hinweis mit dem "." war der entscheidende Tip.
3f980000.usb wird zwar als Seriennummer rausgeworfen, jedoch mit einem tiefen Blick durch
udevadm info --attribute-walk --path=/sys/bus/usb-serial/devices/ttyUSB0
war dann keine Seriennummer vorhanden.
Habe nun ein anderes ATTRS Attribut genommen - und damit geht es.

Leider wurde nicht allgemeinverständlich erklärt wie man das umgehen kann, wie man wo an ein anderes Attribut kommt.

Ich habe drei baugleiche Inverter. Da finde ich keine unterschiedlichen Attribute. gibt es vielleicht noch einen anderen Trick?

Vielen Dank im Voraus für die Hilfe.

Moin.
Vielleicht hilft dir dieser Thread.

https://unix.stackexchange.com/question ... ot-working

Ist zwar nicht ideal, wenn man die Geräte abzieht und an einem anderem USB-Port wieder ansteckt, aber wenn man weiß, wohin jeder einzelne Stick soll... Ich würde mich freuen, wenn es dir hilft.

In eigener Sache: Nun hoffe ich noch darauf, dass nicht wieder einer hinter dem Busch hervorspringt und mit dem Knüppel haut. :evil:

Hallo Ihr!
habe ein USB to 2x Serial

Eine feste Zuweisung mit der Serial geht nicht da, alle beiden Ports die gleiche SN haben!

udevadm info -a -n /dev/ttyUSB0 | grep '{serial}' | head -n1
ATTRS{serial}=="FT8B61MS"
udevadm info -a -n /dev/ttyUSB1 | grep '{serial}' | head -n1
ATTRS{serial}=="FT8B61MS"

Kann man auch mehre Parameter für die Zuweisung verwenden?
Und Welche?

Hallo Blindflug,

schon mal mit fester USB-Port Zuweisung versucht? Wie ich das gelöst hatte findest Du weiter am Anfang.
Vielleicht klappt es damit.
