I have several soundcards for USB. One of them doesn't initialize on boot or reboot. I have always to unplug and replug the cable USB manually that Fedora25 recognizes and initializes the soundcard in USB and PulseAudio. This is annoying.

What does the same as manually unplug and replug an external USB device(soundcard)? How to do this? Is there a command for reinitializing USB devices?

Is this done by triggering UDEV?
