If yours is USB, try using it on the PS/2 port, or vice-versa.
I DO remember seeing a reg tag that had "ID" in it, so you
should look for it. The problem is as you can see in my
first post below, "Logitech" is not mentioned anywhere in
those keys, nor is "mouse".
What you should do, is find all of the mouse drivers
files and search for those in the Registry, that's how I found
those keys below. Since it's the Logitech drivers I assume
that's causing your problem, I guess I'd do like I did and
unpack the driver file download and look at the files. But
you're going to have to install the Logitech drivers again in
order to search and find them in the registry. I'd do it
again, but I have to fix my dad's PC (OE is ruined, more on
that later), but to save you "some" time I searched for
"Logitech" for you and found these areas I pasted below
where "ID" is mentioned. To also save you some time, these are
NOT in the Registry so there's no point in searching for them:
L8042PRT, LCCFltr, LMOUFLTR. I don't remember about the rest.
[HKEY_CLASSES_ROOT\CLSID\{1FE969AE-DED4-11D3-943D-00A0248D3BB2}]
@="CordlessHandler Class"
"AppID"="{1FE969A2-DED4-11D3-943D-00A0248D3BB2}"
[HKEY_CLASSES_ROOT\CLSID\{1FE969AE-DED4-11D3-943D-00A0248D3BB2}\LocalServer32]
@="C:\\PROGRA~1\\COMMON~1\\Logitech\\CdlsHand\\CdlsHand.exe"
[HKEY_CLASSES_ROOT\CLSID\{1FE969AE-DED4-11D3-943D-00A0248D3BB2}\ProgID]
@="CdlsHand.CordlessHandler.1"
[HKEY_CLASSES_ROOT\CLSID\{1FE969AE-DED4-11D3-943D-00A0248D3BB2}\VersionIndependentProgID]
@="CdlsHand.CordlessHandler"
And the same data above is listed under the keys:
HKEY_CLASSES_ROOT\CLSID\{D39F8A6E-F96F-11D2-9AEC-00A0C95AC349}
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{1FE969AE-DED4-11D3-943D-00A0248D3BB2}
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{D39F8A6E-F96F-11D2-9AEC-00A0C95AC349}
Under this key:
HKEY_CURRENT_USER\Software\Logitech\MouseWare\CurrentVersion\Control
Center\Schemes\.Default\Devices\CordlessOptical6\0001\Usability
At the right pane I noticed a string REG_SZ value for
"NewDevice" that may mean something. Mine is set to "Off".
That is also listed under:
[HKEY_USERS\S-1-5-21-854245398-879983540-682003330-1003\Software\Logitech\MouseWare\CurrentVersion\Control
Center\Schemes\.Default\Devices\CordlessOptical6\0001\Usability]
When you unpack the driver file, don't forget about the files
also in the "Win2K_XP" folder. Of course this all probably
moot if you're not using XP or 2K since the drivers may be
different. I have more reg keys but it's too much to put in a
post so I'll send it off list.

Hi Clint,
Pretty impressive ... I've been using an MX 700 for several
years. It's a
great mouse.
I have to use Microsoft Intellipoint drivers with mine however.
Logitech
drivers for some reason re-identify the mouse at every boot.
That means
they won't work through a KVM switch which my mouse has to do.
With Logitech
drivers, whenever I reboot with the mouse connected through the
KVM, the
mouse comes up as a generic 3 button mouse. Microsoft
software id's the
mouse once and then never worries about it again. You can set
custom
functions for the two thumb buttons and the wheel in MS
software they work
fine on the MX700. The only button you lose is the little one
on top.
In your registry exploration did you find anywhere to turn off
the id at
boot function? I haven't researched this for a year or so but
in the
logitech forums, logitech was unapologetic about their mice not
working
through kvm switches. They claimed the mouse functions
wouldn't work
through a switch but I know they do. And I found no one who
had had any
success beating it. I don't understand why logitech won't let
the mouse
type to be set up once and then just assume it's there from
then on.

I was having a severe problem with my mouse cursor slowing
WAAAAY down about half the time when I would have video clips
open, or, when I would have Windows Movie Maker open. It was
so bad, I'd have to move the mouse several feet just move the
cursor from one side of the screen to the other! I would run
out of room on my desk! If I went back to my Desktop, the
problem disappeared. But if a video or WMM got the focus, the
problem would come back.
I'm not sure what the actual root or cause of the problem is,
but shutting down the Logitech software (which was EM_EXEC.exe
in the Task Manager), always fixed the problem. After shutting
it down, the cursor then behaved normally. But the problem
with this is with the software not running, none of the 5 extra
buttons worked! Only the 2 basic buttons and scroll wheel
worked, (but if I had custom settings for them, those custom
settings would not have worked either. It would have defaulted
to typical mouse functions). The mouse is a cordless optical
MX700 8-button. It's a USB but I'm using the PS/2 adapter.
The latest drivers for it are several years old, I fail to see
why they don't have newer drivers. But at any rate that
wouldn't have mattered because these "geniuses" decided to
REMOVE needed features from the latest version! I'm using
9.75, the latest is 9.79.
So this left me with reinstalling them, and that didn't work.
I had also reinstalled my video card drivers prior to this for
another reason, which of course didn't help. Hardware
acceleration was on full, none of the advanced settings in the
ATI control center made any difference.
I then decided to unpack their latest driver version and try to
substitute files one-by-one. This "worked", meaning that even
after manually replacing the DLL files, SYS files, and the main
executable LOGI_MWX.exe (which "activates" EM_EXEC.exe), all
functions still worked, but this did not fix the problem. I
also changed the versions of all of these files where they were
referenced in the Registry. Still nothing worked.
While I was in the Registry I made note of several
"interesting" areas that I thought could possibly have
something to do with this. One that really caught my eye was
"PS2MotionFilter". It was a REG_SZ entry set to "On". So I
searched the whole Registry for that line, and found it in 4
areas, and I then changed that to "Off" in each area, and that
fixed the problem. No more slow cursor movement.
I then created two reg files, one for the Off setting for all 4
Registry areas and one for the On setting should it ever need
to be changed back and forth. Below is the Off version that
worked for me. So if anyone is having this kind of mouse
cursor problem, this might fix it for you. I don't know if
only Logitech has this setting, or if all mice do. The data
entries for each key path below are identical, so I only left
the full data in for the first key just for reference in the
event someone has this problem and does NOT have the
PS2MotionFilter key but may have the other keys. Adding it may
possibly work.
