No new USB devices work - driver install fails
hught78:
I got frustrated and performed an in-place upgrade to Windows 7 Pro (I was on Home Premium) but I'm still having the similar issues. When I did msinfo32.exe the problem driver is:
* Not Available USB\ROOT_HUB20\4&2443D856&1 The drivers for this device are not installed.
I should have mentioned this in my first post but updating the drivers and BIOS was one of the first things I did. No dice.

Please see this post and see the last end for the commands to rescan the device manager.
this should work
Have you tried to download the driver for your machine from hp site
hught78:
Yes, I installed the drivers from the HP site but they did not fix the problem. Also, whenI ran the devcon utility I received the message, "Remove Failed" No Devices Removed.

You have not stated whether the device was shown as connected in usbdeview. If it is not shown as connected, other fixes will not work. If the system shows that it is connected, then you can check whether it is shown in the explorer for you to use.
Try this option,if the device is connected but not shown in the explorer for you to use, then go to Folder options and in the general options, click the 2 options to show all folders. If this helps, pl

Have you tried the " force unsigned driver installation "option in safe mode yet?
