Hello Friends,

I did a fresh install of Fedora 29 on my Inspirion N7110 laptop. My USB 3.0 ports are not working.

Here are some information that I hope it will be helpful.

# /usr/sbin/lspci |grep -i usb

0:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05)
00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05)


# lsusb -t

# lspci -v | grep xhci and # lsusb -t | grep xhci

There is no information being returned about xhci controllers being found.

Can anyone help me please? Thank you.

I've battled this for years. On windows also. In my cae its faulty USB3 Link Power management there are various fixes online (e.g https://askubuntu.com/questions/80271... )but none I have found reliable - so today I bought a USb2.0 hub to plug into my USB3 port to force the disablement of USB 3 lpm. This avenue may help. USB 3 is horrible!
