in ubuntu 15.10 my system added some updates using the automatic software updater. it prompted me to restart my system and after I did my USB ports are no longer recognized.

I just switched over to Linux and do not know how to tell if it was the updates that broke my system or not. I also do not know how to roll back the updates in case it was the update... any help would be great thank you!

Did that upgrade include the kernel? If that's the case, try running the older kernel version from the grub boot screen.

Reboot your PC and when you see grub choose advanced options for Ubuntu and select the previous kernel version from the list, if you can't see grub at boot, press the left Shift key after the bios screen.

You should also look at the output of the terminal command dmesg for any hints at what may be going wrong.

  • That's not quite what I mean, it is good to have the information in the answer rather thann a link, I will show you, it will still be your answer, I will just make an edit.

  • Is there a way I can see a list of the most recent updates? I was not really paying too much attention when I accepted the update to begin with so I am unsure if it updated the kernel or not... Thanks again for your help!
