My Machine  hp 2000 notebook

came w/ Windows 7, now running Windows 10 64 bit


First sign of trouble was kept getting message that YouCam   webcam had stopped working

Uninstalled webcam, don't use it anyway. Was running Windows 8.1 at the time

Then began getting the "USB device not recognized.  The last USB device malfunctioned....

I never use a USB device of any kind.

An unknown device shows up  in the list of USB's in Device Manager and SOMETIMES in Devices and Printers in Control Panel.

Windows cant recognize it.  Updating or uninstalling don't work.

Gradually losing use of keyboard keys.  First g.h, mute, and backspace.  Now more are going


Two Standard USB OpenHCD. host controllers now have yellow triangles


"Windows found driver software but encountered a problem...


Installed Windows 10 hoping it would install new healthy drivers, nope


The disease seems to be  morphing


See the topic everywhere, but no solutions.  Lots of bad advice.  Any help greatly appreciated

Did you do a clean install of 10 or an upgrade?

Your keyboard problem is most probably the keyboard itself.  If you can borrow a regular USB keyboard and try it, that will let you know.

New key boards for laptops are dirt cheap these days ( http://www.ebay.com/itm/GENUINE-NEW-for-HP-COMPAQ-2000-369WM-QE339UA-Model-BLACK-US-LAPTOP-KEYBOARD-/141686510404?hash=item20fd2c9344:g:CjEAAOSw~gRV3p1i ); but, I need the P/N or full model number to make sure its the right one!
