USB ports suddenly stopped working on Ubuntu 18.10 after long time of normal usage. lsusb command show nothing. When I boot system in recovery mode usb ports works normal. Can anyone help me ?

Update
I found some errors in dmesg

  • Do you have the same situation even after using it with live usb?

  • I don't have access to live usb right now. I forgot to say that on my laptop I have dual boot with Windows 10 and on Windows USB works fine.

  • Then download Ubuntu ISO, use unetbootin under windows to make one.

I got the same error in syslog, it's possible we got the same problem.

my problem

I was trying to block some annoying messages in syslog, and I add in grub.cfg:

pci=nomsi

Unfortunately the device generating the annoying messages was the USB HUB, since that gives the 'error -22` :

    [ 1.041264] xhci_hcd 0000:00:14.0: No msi-x/msi found and no IRQ in BIOS
    [ 1.041268] xhci_hcd 0000:00:14.0: startup error -22

my solution

I've removed pci=nomsi from /boot/grub/grub.cfg

  • What's the relation with the question? I can't seem to make a match.

  • @ThunderBird I was too much "ermetic", now I've edited the answer and I give a bit more context
