Monitor USB hubs no longer recognized.  

I have to DELL u2412 monitors with USB hubs connected to my WIN7 X64.
All was working well until…
I had to place my PC on a new desk so I unplugged the connection and when I reconnected (probably to different usb ports).
When I restarted the PC all was working well for a few minutes until windows decided to update the drivers – I probably connected to different ports.
This cause the hubs to stop working completely though they still deliver power.

In the device manager I now have to unrecognized devices which should be the generic usb hubs.

I tried uninstalling the usb generic hub, windows diagnostic tools, reinstall DELL drivers, plugging the different usb ports – nothing.
The hubs are working before windows starts, I know this because my wireless mouse, which is connected via the hub, functions on the bios menu before windows starts.

I even went through restoring my entire disk (using acronis)…all was working well for a few minutes until windows decide to update the drivers…

PLEASE, any help, suggestions?

yes as i wrote i have reinstalled dells drivers.
i neglected to write this but dell provides the monitor display drivers, not the hub. they do not provide the hub drivers since it's a generic one.

Hi janjan21,



Have you tried running WU [Windows Update] to see if it finds the latest drivers?
Or, you could delete the drivers from within the Device Manager and then restart the computer, it should then install the correct drivers!

yes i have done all of the above already and it did not help

I don't have a Windows 7 to hand to give specific access instructions but you should be able to stop windows automatically updating drivers, If you switch the option off it will mean you have to manually install future drivers for this, and other hardware, which is these days probably a good idea.

you should also be able to remove the non working drivers manually - these is normally present a check box option to delete driver files which should give you a "clean slate" to work from

it's impossible to do though i tired it already.
yes i can prevent automatic update but by the time i get to it the update is already done.
I restored my entire system and all was working when windows booted. but it managed to update before i could stop it.

I shall try booting in safe mode next, unhide all usb drivers and uninstall the non used ones.

solved by copy C:\Windows\System32\DriverStore\FileRepository\usb.inf_amd64_neutral_e2b28ecac19a29af files to C:\Windows\inf
in the device manager update the non recognized devices drivers and brows to this location: C:\Windows\inf

ן Microsoft decided to move or delete this files along the way and since they were not found locally it looked for them on the internet and they are missing there as well.
