[LAU] reinitialize soundcards for USB after boot/reboot

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?
