• Question

  • Today I installed Microsoft Office Pro 2013. Later I installed my Brother printer , a MFC-7420 (having to have obtained a new driver from the Brother website because I hadn't used this printer for the past 5 years.) Later (again) I did some printing and everything worked perfectly. I then had to stop what I was doing to go and have dinner. So I turned off the printer but left the laptop on. After dinner I came back to print some more and that's when the troubles started. (a) Nothing would go through to the printer! (b) I can't get anything printed!! and (c) Even my cordless mouse won't work anymore!!!

    To cut a long story short... after various "troubleshooting" procedures were followed I finally established - and the messages I received were - that Windows had disconnected my "Intel(R) ICH9 Family USB Universal Host Controllers... 2937 and 2939" - and yet, upon investigating whether I've got an up-to-date version of these items my laptop's telling me I've got the most up-to-date versions installed!

    I have searched for over 2 hours now, on the Internet, as to what this "Intel(R) ICH9 Family USB Universal Host Controllers... 2937 and 2939" disconnection message really means, why this has happened and, more importantly, what can I do to fix the problem?

    Can anyone help me (in language a complete novice will understand) please?

    Thank you

  • Unfortunately your post is off topic here, in the TechNet Site Feedback forum, because it is not Feedback about the TechNet Website or Subscription.  This is a standard response I’ve written up in advance to help many people (thousands, really.) who post their question in this forum in error, but please don’t ignore it.  The links I share below I’ve collected to help you get right where you need to go with your issue.

    For technical issues with Microsoft products that you would run into as an end user of those products, one great source of info and help is, which has sections for Windows, Hotmail, Office, IE, and other products. Office related forums are also here:

    For Technical issues with Microsoft products that you might have as an IT professional (like technical installation issues, or other IT issues), you should head to the TechNet Discussion forums at, and search for your product name.

    For issues with products you might have as a Developer (like how to talk to APIs, what version of software do what, or other developer issues), you should head to the MSDN discussion forums at, and search for your product or issue.

    If you’re asking a question particularly about one of the Microsoft Dynamics products, a great place to start is here:

    If you really think your issue is related to the subscription or the TechNet Website, and I screwed up, I apologize!  Please repost your question to the discussion forum and include much more detail about your problem, that could include screenshots of the issue (do not include subscription information or product keys in your screenshots!), and/or links to the problem you’re seeing. 

    If you really had no idea where to post this question but you still posted it here, you still shouldn’t have because we have a forum just for you!  It’s called the Where is the forum for…? forum and it’s here:

    Moving to off topic.
