    USB 2.0 Controller - possibly missing?


    I have a new (May 2017) desktop PC running latest Windows 10 vn1703 with 2 USB 3.0 ports on the front and 4 USB 2.0 ports on the back.

    Device Manager only lists USB 3.0, i.e. one 'USB 3.0 eXtensible host controller' and one 'USB Root Hub (3.0)'.

    Should there be any controller or root hub for USB 2.0??

    I have read that USB 2.0/3.0 should be upwards and downwards compatible and yes, the keyboard, mouse and various memory sticks work in all the ports. However I have a USB 2.0 device (a Satmap) which will not work on this machine in any of the ports. It works fine on an older machine that has only USB 2.0 ports (and therefore controllers) running Windows 10 vn1607.

    On the new machine, Device Manager knows the Satmap is connected (lists as USB Mass Storage Device under USB controllers, as USB Device under Disk Drives and also under Portable Devices) but nothing else can 'see' it - neither File Explorer nor the Satmap application software.

    Running Troubleshooter (when it is already plugged in to a USB 2.0 port) just returns the message "USB Mass Storage Device can't work properly with USB 3.0. If the USB 2.0 device is incompatible with USB 3.0, plugging it into a USB 2.0 port can solve the problem."

    Having read through various USB threads, I have tried uninstalling everything under USB controllers but that made no difference.

    Any thoughts on what to try next will be gratefully received.

    There may be a BIOS setting for enabling the USB2 ports in legacy mode.

    Most USB 3.0 ports will work with USB 2.0 devices but shouldn't the other way around. Older hardware is seldom forward compatible with new hardware.

    My latest computer shows a Generic USB Hub for the USB 2.0 ports on the back and a USB Root Hub (USB 3.0) for the rear and front USB 3.0 ports.

    USB 3.0 software should be included with the computer, USB 2.0 is usually supported in the BIOS for use by the keyboard during bootup.

    I have a Corsair Strafe Keyboard with USB 3.0 plugs but my system is 2.0 and the KB works just fine.

    If the legacy mode in bios doesn't work ... and you haven't tried this. With your Satmap connected, plug in a USB stick (USB 2.0 port).

    My laptop won't recognize my USB HDD sometimes (shows in Device Manager, etc), but soon as I plug in a USB stick (and it gets recognized) the USB HDD shows up in file explorer and I can use it. Don't really know why this works.

    Thanks for reply. I can't find anything about USB2 in BIOS. Not entirely sure what I would be looking for and where.

    My computer has only the USB 3.0 Root Hub. No 'Generic USB Hub' at all. Hence I am wondering if this is the problem with my device not working but I may be clutching at straws.

    Thanks. This would have been great if it worked but, sadly, it didn't.

    As I mentioned I have added a USB 3.0 card to get more ports. If the software isn't contained within Windows you should have gotten a CD from the manufacturer of the motherboard or the vendor of the computer to install the drivers. USB 2.0 may not be shown in the BIOS as such, may be Legacy USB with is needed to allow a USB keyboard necessary to make changes. Have seen older computers need a PS/2-attached keyboard to make changes before a USB keyboard can be used. Haven't seen a computer yet that has BIOS support for USB 3.0, usually gets that when the Operating System is installed and drivers installed.

    Here is a screenshot of my Insider Preview computer, USB2.0 only:

    Thanks - mine certainly looks inadequate. Unsurprisingly every port (2 USB3.0 and 4USB2.0) is in "Hub #1".
