USB mouse not working after installing Ubuntu 16.04

Have you tried it in a different speed port (USB2 and USB3)

Have you set your BIOS to allow legacy mode?

No I didn't try those things because as I wrote in the question the solution in the first linked question worked for me.
In other words this solves the problem :
    sudo rmmod usbhid
    sudo modprobe usbhid
However, if I restart the machine I have to do that again.
So I'm reporting it so a permanent fix can be made upstream please.

Add them in /etc/rc.local above the 'exit 0' line.

Is this a known bug?

I looked for it as known bug and couldn't find it.
The solution above and adding to /etc/rc.local is a good workaround.

I thought this issue was a bug report. Is it not?

You could report one

I tried reporting a bug. I ran ubuntu-bug and got these error messages.

/usr/share/apport/apport-gtk:16: PyGIWarning: Wnck was imported without specifying a version first. Use gi.require('Wnck','3.0') before import to ensure that the right version gets loaded.

So I now got a bug reporting a bug ?

please try remove a package

$ sudo apt remove gnome-software

@andrew-woodhead666 adding those lines to /etc/rc.local appears to have no effect. I still have to type them every time I restart otherwise the USB mouse doesn't work.

@orca-rexx sudo apt remove gnome-software seems quite drastic -- like, remove all the software? You have 0 rep so I'll assume it was trolling.

Summary: Typing 'sudo rmmod usbhid' then 'sudo modprobe usbhid' makes the USB mouse work. But I have to do that every time I restart. It was working fine with 15.10 and stopped working when I upgraded to 16.04.

This web interface started to give me the option to create a bug based on a question so I did that now without needing to fix the bugs with ubuntu-bug program.

> remove all the software?

"gnome-software" package and "gnome-software-common" package

-> Those 2 packages

@RxOrca Gnome is the desktop. You're suggesting removing major packages. Why? Is it a wild guess or is there some reason for suggesting these packages. You have 0 rep so in this case I'd need more info from you. Will removing these packages help ububtu-bug problems reported above or the USB mouse problem? It isn't clear which of those two problems you're suggesting this for.
