udev - symlink USB HUB port

[Marekuss]

Ahojte kolegovia,

Riesim specificku USB/udev poziadavku a to, vytvorenie symlinku na USB HUB Port -> usb port passtru do LXD
majme 4-portovy USB HUB, kde je pripojene USB-CDC zariadenie (alebo ine), je mozne v Linuxe jednoznacne cez udev spravit symlink na dany USB HUB Port (nie device/zariadenie)?

zatial v poriadku ale...

systemd-udevd[2405]: 1-1.3.2: No reference left, removing '/dev/usb1-2'


Vyzera ze udev mi vytvoril symlink na dany USB port, ale po enumeracii celeho USB-CDC (coz este som nedosiel ako mu zabranit) symlink prestal platit tak ho zmazal..

Je vobec mozne vyriesit popisanu situaciu?



AD: symlink na konkretne USB-CDC zariadenie cez udev funguje, aj forward do LXD, osobne by som ale chcel forwardnut dany fyzicky port z USB HUBU, nakolko chce bindovat port a nie zariadenie, co je pre mna viac genericke...
