Specs: Windows 7, Intel 5
I have aproblem with the USB ports on my laptop. Whenever I plug in a device to any of the 4 ports on my laptop, I get this "device not recognized by Windows 7" I have tried all kinds of remedies, like uninstalling and reinstalling the drivers for USB. Also I have done a Windows 7 repair as well as a system restore, and I get the same error. What could be wrong??

possibly your motherboard. Was windows 7 the origional OS of the laptop? Did the usb ports ever work with windows 7?

try these ...goto Control Panel>System and Security>System>Device Manager>Universal Serial Bus Controller...if any yellow icon shows in them then..you need to install drivers or they just maybe disabled...click on the ports and enable them

Yes , my laptop came with original OS of Vista. And yes, USB ports did work with Windows 7 for over 6 months now.

You may want to see if there are updated chipset drivers for the laptop. The drivers may have become corrupt for some strange reason.

Also, you may have been still using the original Vista drivers which will often work, but after a recent security or other update from MS, they may no longer work. Look for specifically Windows 7 drivers for your model.

You have to be a little bit crazy to keep you from going insane.

OK yes I did look for drivers for Windows 7. Only thing, it seems HP does not have drivers for Windows 7 on model dv9010us laptops.

Bad situation. Perhaps flashing the BIOS would make a difference. Or if the MB is made by someone else, they might have 7 drivers. Or maybe there's a similar model with 7 drivers you could try.

HP strikes again! This is not unusual for them. You should have run the Windows 7 compatibility tester before you installed it, and even it it said you were Ok, I would still have recommended downloading ALL drivers for Windows 7 (your version) before you started and putting them on a flash drive so they would be ready when you were ready to install them. It would have saved you the problems now.
See if it will let you run the driver in compatibility as Vista. It works for programs, it may work for the driver too.
