i am forced to do sudo -s, enter my password and then enter echo -n "0000:00:14.0" | tee /sys/bus/pci/drivers/xhci_hcd/unbind this is because somehow my usb is broken on motherboard and it makes cpu 100% with full fan running, some over current issue. this command disables all usb. the problem is i am forced to open terminal, up, enter password, enter, up, enter, exit, exit on every boot time. it gets tiring and i found no good way for bash to automate typing password on sudo -s. any ideas?

The hack would be to put it in rc.local but don’t do that. The more correct way would be to make an init.d/systemd service to run on boot, which executes as root. The most correct solution would be to get a new keyboard or re-pin your usb connector.

There are multiple ways to fix this, here's some of the methods of the top of my head ranked best to worst: 1: Write a udev rule to unbind the 0000:00:14.0 device when detected. This is the best solution, and a google search can show you how. But does require some underlying knowledge of devices and udev. [A][B][C] 2: Create a systemd startup service that runs your above commands at startup. This is less elegant than the above, but the end result would mostly be the same. [H] 3: Configure sudo to not require a password, then create an xdg-autostart script that runs your command.

Other answers are better, but in the shell you can do above without a separate sudo login. For example: echo -n "0000:00:14.0" | sudo tee /sys/bus/pci/drivers/xhci_hcd/unbind
