udev rules

Posted on

Dear all,
With RHEL7, I used the udev rules to manage the usb device according to my needs. I wrote my rules like this one:
ACTION=="add", SUBSYSTEM=="usb", ENV{ID_VENDOR_ID}=="0403", ENV{ID_MODEL_ID}=="6001", ENV{ID_MODEL}=="PEAL9284", RUN+="/usr/local/bin/manage-libvirt-devices.sh attach"
It seems, with RHEL8, that is changed. The parameters likes ENV{ID_VENDOR_ID}, ENV{ID_VENDOR_ID} or ENV{ID_MODEL} are no more taken into account. I tested new rules using attributes (ATTR{idVendor}, ATTR{idProduct} or ATTRS{Product}) but that's the same result --> no action.
I don't understand why. According to the recent documentation, that should be ok.
So, do you have some idea about my critical problem?
Thanks in advance for any help.
Best regards
Stéphane
