Windows 7: USB ports work only once until shut off

USB ports work only once until shut off

I recently upgraded to 7. I have 3 USB ports on my HP Pavillion dv6 laptop. I find that after booting up windows, I can plug something into my USB port (like a wireless mouse receiver), but after I remove the device from the port, all USB ports stop reading any USB devices, regardless of whether it is the same as the first device I plugged in or not. Any help would be greatly appreciated. Thanks!

Try going here to download the latest chipset drivers for your machine.

Hopefully that will solve the problem.

Good luck!

Need more details on your dv6 as there are a few models if it uses the nforce chipset this fix might work - set up a restore point firstly:
You encounter problems when you move data over USB from a Windows 7 or Windows Server 2008 R2-based computer that has an NVIDIA USB EHCI chipset and at least 4GB of RAM
If it uses intel - the intel chipset installation utility, and also you might need to install the intel matrix storage manager :
