Windows 7 not recognizing usb device

[pplrelax]

hello.
I purchased a drawing tablet that connects via USB to my windows 7 machine.

I installed the drivers and I see the proper ones on Device Manager.
Yet after it is installed, Windows 7 does an extra step and searches for the drivers.
It says that the drivers could not be found. But the drivers are installed. I am looking right at them.

I uninstalled that "unknown other device" manually from the device manager and restart the computer.

The device works. The computer recognizes the drawing tablet and it works for a little while.
But again, Windows 7 begins its automatic search thing. It does something that makes the tablet not work anymore.

I'm baffled on what it could be.

Go to Start–>Search type in gpedit.msc
Click the file to open the Local Group Policy Editor and show Windows who is in control!!
You want to go here: Computer Configuration->Administrative Templates->System->Device Installation. Click on the subfolder Device Installation on the left and on the right side you will see the possible restrictions.
Right Click on Prevent Installation of Devices not described by other policy settings and edit this option, set it on ENABLED.
Reboot Windows and enjoy its inability to pollute your system with its standard driver, open gpedit.msc again and revert the change so you will be able to install your driver.

Let me know if this works. It'll stop Windows from auto installing drivers.

gpedit.msc is not available in Win. 7 home version

I want to try what you told me but gpedit.msc isn't available.
Is there another way?

Shoot, that's only available in 7 Pro. I'm sorry. I'll look into another option for you.
