    USB2 ports do not function, USB3 ports do

    I have on my computer case 3 USB 3.0 Ports, and 9 USB2 ports. All the USB 3.0 ports work with everything as expected, but none of the USB 2.0 ports do. Those USB 2.0 ports do not work with my keyboard, mouse, printer, or USB drives. I do not know if this is a hardware failure, or a bad driver installation.

    OS: Ubuntu 18.04
    Motherboard: Gigabyte 970A-D3P

    Some diagnostic commands, and their outputs, with a USB Drive plugged into a USB2 port:
    Code:
    n@ubuntu:~$ lsusb
    Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

    Bus 008 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    n@ubuntu:~$ ls /dev/ | grep sd
    sda
    sda1
    sda2
    sda3
    sda4
    sdb
    sdb1
    sdb2
    sdb3
    sdb4
    sda and sdb are RAIDed together in a RAID1 Mirror configuration. The USB Drive does not show.

    I would appreciate any other steps to take to find out if anything is wrong with the USB2 driver.

    Re: USB2 ports do not function, USB3 ports do

    There are a couple of settings in your BIOS setup that you should check. They're sort of described on pages 45 and 46 of your owner's manual. If you don't have one, you can see an on-line version at https://www.manualslib.com/manual/54...page=45#manual

    In particular, make sure the setting for "onboard USB device" is set to enabled (the default).

    Specifically in regard to Linux, I'm not sure which of the options for XCHi and EHCi handoff is recommended. EHCi is the standard for USB 2.0, though, so you might just flip that setting, then press <f10> to save changes and exit setup. That will reboot the machine. See if it makes a difference. If it doesn't, repeat the drill and put it back to the default setting.

    Same for the "legacy device support" setting.

    Unrelated, but since you're in settings: If you haven't replaced the battery on the motherboard in the last three years, now would be a good time to do so.

    In my EUFI Firmware Settings has separate enables for Onboard USB, and Legacy USB are and were on. Testing with Legacy off did not make a difference.

    I tested all four combination states of XCHI and EHCI being on and off. The USB2 ports did not work with any of them.
