The problem:

Every time I reboot the computer the ID of the cables is changed (sometimes even without reboot).

The doubt:

How do I fix this situation?

Try using the links from /dev/serial/by-{id,path} instead.

Ah, I should have a look at this, too. What I use here is /etc/udev/rules.d/70-persistent-usb.rules to give them unique names. SUBSYSTEM=="tty", ACTION=="add", ATTRS{idVendor}=="067b", ATTRS{idProduct}=="2303", KERNEL=="ttyUSB*", SYMLINK="synscan" SUBSYSTEM=="tty", ACTION=="add", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6015", KERNEL=="ttyUSB*", SYMLINK="focus" SUBSYSTEM=="tty", ACTION=="add", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", KERNEL=="ttyUSB*", SYMLINK="eqmod" In this case it's easy because already product/vendor IDs are different. There's also other attributes available, like serial numbers, that can be used in those rules. Check maybe with lsusb for unique parameters for the units. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
