Hi, my Logitech LX8 Cordless Mouse pointer shudders from time to time. When it happens I move the recorder piece (if that's the right term) from one USB port to another. That usually corrects the bahaviour for a while.

I had a look at the devise drivers (through control Panel) and there were about 4 of them. The first being one by Kaspersky (I've got KAS Internet Security installed), then Logitech and others.

I downloaded and ran Logitech SetPoint and then had another look at the devise drivers expecting there to be only one but now there are seven listed:

Kaspersky Lab 8.0.0.25
Logitech 5.33.10.0
Ditto
Microsoft 5.1.2600.5512 (xpsp.080413.2108)
Microsoft 5.1.2600 (XPClient. 010817.1148)
Logitech 5.33.10
Ditto

Some are shown as sy files others as .dll.

Should there NOT be JUST one driver listed, if NOT could someone please tell me why?

Why would the Kaspersky be the driver of choice, especially after I ran SetPoint?

Is there a way to select say the second driver in the list (Logitech 5.33 etc), to see it that makes a difference?

Thanx
 
That's probably a filter driver.

How is your cordless mouse powered? Shuddering cursor is almost always low battery in my experience.
 
Thanx, I put in a new set of batteries and thus far I haven't had a shuddering cursor.

I'm NOT sure what a filter driver is, but from Control Panel, Mouse, Driver tab - that screen Shows: Logitech HID Compliant Cordless Mouse. When I select the Driver Details Box/button, it shows the drivers I've listed in the opening post. Kaspersky is shown as the first one and I (probably incorrectly) thought that was the driver selected by the system.

It shows it as Driver files:

C:\WINDOWS\system32\DRIVERS\klmouflt.sys and then below as Provider Kaspersky Lab etc

Thanx

Would that be a filter driver?
 
Yep, that looks normal considering you're running Kaspersky software.

A filter driver in itself is pretty generic. In your case it will be performing an anti malware function like obfuscating mouse movements or something
