USB Ports and Controllers 2.0 vs 3.0
I have a new (May 2017) Inspiron Desktop 3668 running latest Windows 10 vn1703 with 2 USB 3.0 ports on the front and 4 USB 2.0 ports on the back.
In Device Manager I see 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??
Reason for asking is that I can't get my Satmap (Garmin-equivalent device) to work on this machine in any of the ports. It works fine on an Inspiron 620 with Windows 10 vn1607 and USB 2.0s only.
On the new machine, Device Manager know it is there but nothing else can 'see' it - not File Explorer nor the Satmap software. Running Troubleshooter (when it is already plugged ito 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."
Any thoughts gratefully received.

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.
