How can I force my pci card usb bus numbers to stay the same after reboot?
1
I have a few identical usb sound cards and wrote a udev rule so they each get a persistent name matching the specific port they are attached to. Now I added a pci usb 3.0 card and that is playing around with usb bus numbers. sometimes the pci usb gets loaded before the built-in usb and has a lower bus number and sometimes after and gets a higher bus number.
What can I do to force the bus numbers of the built-in and pci card?
If that can't work what can I do to get persistent device names for identical (and without serial numbers) usb devices where the only difference is the port they are attached to?

First idea is to modify the udev rules to identify built-in USB root hubs, and use the USB port structure (lsusb -t) once you matched the hub.udevadmhelps to identify attributes you want to match against.

I don't understand what you want me to do. I was (am) asking how to use udev to give permanent structure to the usb hubs and ports.

@AlexP. That is different. I am having an issue because the devices are getting different paths after reboot even without hardware changes. I will update my question with differentlsusb -toutput.

First idea is to modify the udev rules to identify built-in USB root hubs, and use the USB port structure (lsusb -t) once you matched the hub.udevadmhelps to identify attributes you want to match against.

I don't understand what you want me to do. I was (am) asking how to use udev to give permanent structure to the usb hubs and ports.

@AlexP. That is different. I am having an issue because the devices are getting different paths after reboot even without hardware changes. I will update my question with differentlsusb -toutput.
