Unable to use new keyboard and mouse  

Maybe I am not making myself clear you can quite happily uninstall all the not connected devices, you can even uninstall the connected devices.(that should by this stage be disconnected anyway) Windows makes a data base of drivers, every time you plug in a USB device this data base gets updated to enable the device to be reinstalled if you remove it and plug it in again even if you use a different port. The important point here is this data base can become corrupted causing problems and that is what I am trying to sort out here.
The only stipulation is; after deleting the infcache.1 file you must plug in a device that was working before ie your Toshiba mass storage device.

Yes, that is exactly what I did.

All those drivers that show as unconnected except for the mass storage one were created when I plugged in the mouse and keyboard. If I uninstall them, the mouse and keyboard will stop working even though it still has the device drivers than say connected.

OK thank you that is very strange

In the last picture have you disconnected the Port 0006 Ut165 flash storage device? as it shows as no longer connected

When you first installed the drivers were the mouse and keyboard already plugged in?

Do you have a card reader or other hardware that is connected internally to a USB header on the motherboard? If so, disconnect it/them and see if that helps.

I think we have exhausted all options here except a fresh install let us know how you get on
