Windows 7 will not recognize USB devices. Have no keyboard or mouse access system.

We have a 2 year old HP tower that lost access to the USB device ports.   Keyboard, mouse, flash drives do not work.   It is a small web-only machine that is used as an e-mail/web access point.

 

After a reboot yesterday, they report the system will not allow the to move the mouse ponter or type anything.

 

The keyboard and mouse are USB devices and the machine does not have the PS2 ports.

 

Any suggestions on how to access the machine to diagnose?

 

Thanks for any help.

Hi,

 

Thank you for posting your query in Microsoft Community.

 

As per the issue description, you are facing issues with USB devices and ports are not working. However, to help you suggest steps to resolve the issue, I would appreciate if you could answer the following questions:

 

1.       Do you receive any error message or error code?

2.       What are the troubleshooting steps did you try in order to resolve USB issues?

3.       Have you made any changes on the computer prior to the issue?

 

Follow the suggestions listed below for a possible fix:

 

Method 1: Let us start with running the hardware troubleshooter and check. Follow the article mentioned below for more information:

 

Open the Hardware and Devices troubleshooter

http://windows.microsoft.com/en-us/windows7/Open-the-Hardware-and-Devices-troubleshooter

 

Method 2: If the above step does not help us to diagnose the issue, uninstall the drivers for USB [Universal Serial bus] host controller and restart the computer. Let Windows install the generic drivers and then see if it helps you to fix the issue.

 

1.       Open Device Manager by clicking the Start button, then Device Manager in the search box.‌

If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

2.       Look for the device under USB [Universal Serial bus] host controller, right click on it and select Uninstall.

3.       Reboot the computer.

4.       On reboot, Windows 7 should re-install the drivers automatically.

 

Hope it helps. For any further Windows related assistance, feel free to contact us and we will be happy to help.

Hi Imran,

Please review my statements above.   As I have indicated, the USB devices do not work.  This means I have no keyboard or mouse to "select", "click", or even type anything.

 

The machine boots up.   Nothing can be entered or selected.

 

My question is how to access the machine when the mouse and keyboard aren't recognized.

 

Thanks...

Hi,

 

Thank you for the prompt reply.

 

I’m sorry that could mention the workaround for this. You may connect the different keyboard and mouse then try those methods provided in my previous post.

 

Please get back with the results.

Please read carefully.  Thank you in advance.

 

1.  The machine has no other access ports except USB.  No serial, no PS2.

2.  We tried other "USB" keyboards and mice.   They do not work.

3.  The original keyboard and mouse works on other machines.

4.  The machine (yes, it was cheap) only has USB connections.   NO PS2 ports are available.  So can not use a USB to PS2 converter.

5.  The machine boots.  It can be powered off by the power switch.  But no USB devices work.

 

To enter, select, or point at anything requires the USB ports to be working.  They are not working no matter how many times we boot the machine.

 

 

I am not aware of any "other" type mouse or keyboard on the market.  Only USB or PS2 connected.

 

 

Regretfully, there isn't a "recovery" disk available to this machine.  Otherwise, I'd try it.

 

 

Do you have any suggestions (what hardware is needed) to try and follow your recommendation?

Hi Tech-2013

 

Did you get a solution to this. I have an Inspiron 1545 with only USB ports running Windows 7 and like you I have lost all access to these ports. Fortunately it is a Laptop and so I can still use it. However I prefer to use mouse and wireless Keyboard and also USB memory sticks, earphones etc. None of which work any longer

 

I have uninstalled the ports and rebooted and though it installs all the ports on start up and also the software for the keyboard and hubs it does not even register them when they are plugged in.

 

I have also used the diagnostic tool but it gives no solutions.

 

Anyone help please. Roger

This site was useless.   No one answered with any common sense.   My client ended up purchasing another machine and I had to pull the hard drive to get the data off of it.   They were not happy.

The user ended up buying a new computer.    I pulled the old drive and extracted the data.  They were not happy, but its all I could do.

Unfortunately I can't give you an absolute fix, but I think I can shed some light on this problem.

I experienced the exact same issue with a four year old HP Compaq dx2400 running Windows 7 Pro.  I noticed that during the BIOS boot the keyboard responded appropriately - I could even hit F10 and enter setup.  When I did I checked that the USB ports were still set to active, so it wasn't a hardware or BIOS problem.  It is absolutely a Windows issue because as soon as Windows took over the keyboard and mouse went dead.  Luckily for us this PC has PS/2 ports and I happen to keep some old keyboards and a USB-to-PS/2 adapter around.  When I hooked up the PS/2 devices the PC booted normally.

 

Now, two significant things:  1) the PC is joined to a network with Windows Server 2008.  When the PC booted I logged in with an administrator account, and not the same user account that had been on before.  2) As soon as the PC booted there was a message window stating that the PC had to be rebooted in order for recently installed updates to complete installation.  So there were some lingering updates that were halfway installed at the time that the PC last was shutdown (and I don't know if this was manually by the user or "automagically").  I also don't know if part of the issue was that the user account didn't have the authority to allow these updates to be applied.  In any case, I rebooted to allow the updates to complete, then shut the PC down hard, disconnected the PS/2 devices, reconnected the USB devices, started the computer, and everything worked normally.

 

So, again, this is absolutely a Windows problem (and I find the response from Mohammad_Imran pretty lame - it's like telling a mechanic that your car won't start and he says to drive it over so he can take a look at it).  It also seems to have something to do with partially installed updates.  In this case the updates were in the categories of "Security Update for Win 7" (KB2862330, KB2864085, KB2862335, KB2884256, KB2876284, KB2847311, KB2883150, KB2868038, & KB2864202), "Update for Windows" (KB2888049, KB2882822, KB2852386, & KB2846960), "Security Update for Microsoft.NET Framework 3.5.1 on Windows 7 SP1 x86" (KB2861191, KB2863240, & KB2861698), and "Cumulative Security Update for Internet Explorer 10 for Windows 7 Service Pack 1" (KB2879017).  Four of these updates had actually failed on install the day before (KB2864085, KB2862330, KB2862335, & KB2888049) all with error code 80070490.  Now the specific updates that others may have will probably differ from these, but I would bet that there is an underlying problem that Microsoft needs to look at.

 

So if you are lucky enough to have PS/2 ports on your computer there is a workaround.  If you don't the good news is that your machine isn't toast, you just need to repair, restore or reinstall Windows.  Just test first to see that your keyboard works with BIOS setup before it goes dead, then you'll know for sure.

I should add that booting in safe mode didn't help either.
