Trying removal & preventing installation of duplicate keyboard driver

Apologize for this long post but I am trying to be as thorough as possible to provide the necessary info.

Attached is the BIOS USB page & setup listing two keyboards. When checked, there really are two identical versions of the same driver (Microsoft 6.1.7601.17514) in the Device manager.

The problem is that the keyboard goes crazy after a couple of minutes. Keys don't generate the correct character, the Windows key is not working, and the left or right arrow keys bring forth windows open in the background.

The source of the duplicate is Logitech, passed through the Microsoft update and is installed by the Logitech Download Assistant, (software update released in August, 2012).

C:\Windows\System32\DriverStore\FileRepository\lvpro5v.inf_x86_neutral_793a06f60f3fecc2\LogiDPP.dll
C:\Windows\System32\DriverStore\FileRepository\lvpro5v.inf_x86_neutral_793a06f60f3fecc2\LogiDPPApp.e xe

C:\Windows\System32\LogiDPPApp.exe
C:\Windows\System32\LogiDPP.dll

Having four USB keyboards (two Logitech and two Microsoft), one of each is a wired, and one of each is wireless, to test the problem. Currently, I am using a wired Microsoft 600 keyboard and the problem is the same with all.

The mouse is always the same. It's a Logitech M510 wireless and all batteries are fully charged.

While in Windows, I managed to force the removal of LogiDPP.dll, and the 2nd keyboard driver disappeared and everything worked fine, until a reboot.

LogiDPPApp.exe could not be removed in Windows, so I booted into Xubuntu Live CD and deleted the files from System32 and \System32\DriverStore\FileRepository.

When rebooted, the BIOS again displayed two keyboards and one mouse, (I don't know it knew), and when Windows loaded, the above mentioned files were back in their folders.

Also uninstalled Logitech Download Assistant and hid the new replacement update

How can I get rid of them permanently?

Hi Itaregid, Thanks for the advice which I followed through. Now working with a Mirosoft 600 wired keyboard and a generic mouse and there is only one driver for each, as hoped for. By the way, I don't use unified dongles. each hardware had its own dongle.

I am now going to plug in a Microsoft 800 wireless keyboard, and the Logitech M510 wireless mouse. Will return to let you as soon as I reboot.

Using the above mentioned wireless devices, everything reverted to the same as before. The BIOS indicated
two keyboards and two mice. Therefore, the OS installed two drivers for each.

So, I surrendered and installed the Logitech SetPoint software, using the wireless Logitech K330 keyboard and the wireless M510 mouse, and unified them. The device manager now displays one MS HID device driver, and one Logitech HID device driver for each. But on boot, the BIOS recognizes only one keyboard and one mouse. I just hope that the keyboard doesn't fail in 15 minutes as before, otherwise I couldn't care less if it installs 10 drivers each.

This leads me to believe that the problem lies with the motherboard USB controller, even though I updated all motherboard drivers to the latest versions a couple of days ago when I re-installed Windows 7 from scratch and every analysis tool of the manufacturers (ASUS, AMI and Intel) indicated that everything is perfect. Thanks for all your kind help and advice.

Yes, the devices had to be disconnected because there are only two USB ports on the front panel. As I wrote above, afterwards connected the Logitech components and unified them in one dongle. Then, the BIOS indicated one of each, but nothing was resolved. Just before reading your post, I was typing a letter using Linux Xubuntu and the keyboard returned to its bizarre behavior. This made me realize that a dead horse is being flogged because the problem is not OS related.

I have four USB ports at the back of the case. It is where the dongle(s) were plugged in when the problems started. Also, I wouldn't know which two out of the four you mentioned, should be used. I am only using the front USB sockets for convenience, while I am trying to solve this mystery.

Just checked the manual and there is no difference which USB port used for the keyboard or mouse. I have all the motherboard & components' latest driver updates, as well as the original motherboard disk. i will reinstall the drivers starting with the installation CD because it has an automatic Internet connection to the MB manufacturer's updated device driver database. Will post the results.
