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!
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 :

Intel(R) Matrix Storage Manager
A simple fix is to check your Power Options:
Control Panel --> Hardware and Sound --> Power Options --> Change plan settings --> Change advanced power settings --> USB Settings --> USB Selective Suspend Settings:
Set both options to disabled. Do the same for all your power options (change at the top: Balanced/ High Performance/ Eco.. etc. )
Just changing the registry did not do it because the power settings kept changing it back so this fix should do.
I realize this thread is infinitely old but it came up when I was googling my issue so hopefully someone will benefit from this (tried everything before I stumbled upon this)
