Windows 10: 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.

Windows10 USB xHCI Compliant Host Controller code 10

Hi,

I was thinking you were going to put the Linux on a DVD.. but putting it on a flash drive would answer more questions... Like the point that it boots, and then fails..

At this point I am thinking that the issue is with the USB 3.0 part of the controller...

My guess is that when you boot, Linux is using some type of basic USB 2.0 driver, and then runs into problems with the USB 3.0 driver when it gets to that point...

Linux wouldn't use the same drivers as your Windows installation... It requires drivers specifically for Linux...

USB 2.0 and 3.0 run through the same controller so that USB 3.0 can run a 2.0 device... USB 3.0 uses a 2.0 connection as part of the 3.0 connection to make this possible...

Unfortunately, it sounds like a hardware issue to me, but Toshiba may have more insight on that....

It is possible that the failure is a coincidental thing with the installation on the Windows Updates, and I suppose that there could be something about the updates that may have actually caused the failure... But that is just a wild guess..

I would be curious as to what Toshiba has to say... Good luck with that...

 

USB ports 3.0 after update

Hi James,

There is no need to disable USB 3.0 in order to get a USB 2.0 device working. Technically speaking, the legacy USB 2.0 works in parallel with new the USB 3.0 over a separate set of legacy wires.
The USB 3.0 ports are under control of a different controller which also supports USB 2.0. Disabling the USB3 functionality is as simple as going to
Device Manager, and setting the eXtensible Host Controller (in USB section) to
Disable.

Should you have other queries and concern, feel free to post back.

 

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.

 

Here's a screenshot of my Device Manager and USB:



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".

 

After a lot of uninstalling/reinstalling of drivers and software, my problem is solved but I’m not entirely sure why. Nothing individually made any difference. It’s as though there was some sort of cumulative effect.

One notable change is that the notorious “Device . . . could not be migrated” message has disappeared. I was getting this on virtually all USB devices, most (but not all) of which continued to work regardless. It may just be coincidence but it was around the same time as uninstalling all the ‘history’ of USB/Disks/Portable devices/and others from within Device Manager (by clicking View/Show hidden devices then rightclick/Uninstall all the ghostly greyed out items).

Now instead of Events showing:
Device deleted, Device not migrated, Device configured, Device started

I just have:
Device deleted, Device configured, Device started

However I’m sure I went round the loop of doing the Uninstalling from within Device Manager more than once before achieving this so it could be coincidence.

Anyway, the Satmap works (for now) in both USB2.0 ports and USB3.0 ports, so maybe my USB2.0 controller theory was completely irrelevant. Apologies for any red herrings.

Many thanks to all of you who took the trouble to reply.
