USB Device Not Recognized?!?!

post #1 of 16
Thread Starter 
I am running Windows 7 and for what ever reason the "USB Device Not Recognized" is always popping up in the bottom task bar. I have checked all of my devices that are plugged in using USB and they are all working fine. All that I have plugged in is, Logitech G15 and G5 and my wireless adapter. I have already tried disabling the device by clicking the icon and uninstalling but the thing keeps popping up. Does anyone know why it would be doing this and what the fix would be? Thanks

There are two things with the "!" next to them. I have tried unplugging everything then plugging it in one at a time. Nothing has worked.

There is a small chance that it's a device that was attached at one point, and for some reason the system is still trying to access/detect it as if it were attached.

Add the following environment variable (Right click on Computer from Start - > Properties -> Environment Variables -> Add)

Name: devmgr_show_nonpresent_devices
Value: 1
Log out and back in
Go into control panel -> Device Manager
Then go to View -> Show Hidden

Expand your USB controllers, look for any entries that have a faded/transparent icon next to them.
Remove all such entries.

Hope that works. If not, you could always reload the chipset drivers to have the USB controllers all re-detect from scratch.

You can also try to delete all USB root hubs from the device manager. Once you delete those go to the top right click on your computer name and select Scan for Hardware Changes. Once you do this it should detect all of your USB root hubs again and properly install them.

Do you have any kind of card reader or anything of the like in the machine?

Do I add that under User variables or system variables?
