How to restart USB ports on Linux?

Question

linux

Hello. USB 2.0 ports are not working on my laptop. Only 2 USB 3.0 ports work, and then with failures. In short, these USB 3.0 ports only work with USB 3.0 devices. With flash drives 2.0, with a mouse, etc. ports are not working. In the manager, all ports, including 3.0, are marked as "Unknown USB device (device descriptor request failed)". In order for USB 3.0 ports to work with 2.0 devices, I restart the “USB Root Hub (USB 3.0)” in the manager. After restarting, everything works. I have had this problem for a long time, I tried everything, something burned out inside. and the masters here are not trusted.So I'm going to put Linux on this laptop.How can I do the same in Linux so that the ports work with 2.0 devices?Just googling, tried modprobe in the terminal, does not help.

Try the methods described here:

It seems to me that in bash the easiest way is:

for i in /sys/bus/pci/drivers/[uoex]hci_hcd/*:*; do
  echo "${i##*/}" > "${i%/*}/unbind"
  echo "${i##*/}" > "${i%/*}/bind"
done
