Windows 7: Plug and Play not working after Windows 7 updates

Plug and Play not working after Windows 7 updates

Just as the title says... I have actually had this problem every time I've re-installed the OS and can't seem to figure out how to fix it. When I install Windows 7 x64 and plug in my mouse or printer right away they will discover the drivers and work automagically. After I go through the Windows updates they just don't seem to work anymore. The only thing I've been able to do to get them to work is run this little MS program(http://windows.micro...ith-USB-devices) I found that apparently forces what I have plugged into the USB port and isn't responding to install drivers and work. I just don't know what to do so I don't have to run this program any time I try to plug something into the USB ports.

What's kind of strange is I have an external drive that I plug in and it works before and after the updates without running that program. Anyone have any idea what might be wrong?

Using a HP Pavilion g7 1075dx Notebook PC just fyi.

Edit: Actually I just tested unplugging the mouse and printer after they were working, restarting the system, and trying to plug them back in again. They don't work again. So as it stands I would have to run that little MS Fix It program every time I plug them in to get them to work.

Have you installed sp1? try this firstly, if you have already installed SP1 look below : Learn how to install Windows 7 Service Pack 1 (SP1)

Some other ideas copied from this thread which has more : USB device not recognized - Help!
OK, I finally fixed my issue with the USB ports not recognized, here is what I did:
*Unplugged all USB devices
*went to Device manager in windows 7
*uninstalled EACH Root Hub USB driver
*Powered off my computer/unplug
*Powered back on
*Reconnected each USB device
*They all Loaded sucessfully.
I hope this helps.

Another possibity : try updating your chipset drivers this is much the same as the above but the latest driver may make a difference.

Try reinstalling or updating the mouse and the printer software.

It seems to me a software issue corrupted by the updates so here is another solution - have the w7 OS install dvd handy as this tests for corrupted system files : start > type cmd > right clight CMD select "run as admin" > type or paste the following : SFC /scannow

Suppress Plug and Play UI
Is there anything in Windows 7 that will suppress the UI pop-ups when a new device is attached to a computer? There was something like it in XP. See this: Hotfix adds new functionality to suppress Plug and Play-related UI messages in Windows Server 2003 or in Windows XP.
