XP won't let me use mouse in Safe Mode

by xin / November 4, 2003 4:28 AM PST

XP freezes my mouse solid to the screen in Safe Mode. It won't let me use it.
I use keyboard to scoll tro' desktop icons but with no mouse, i can't do anything. I simply shut the system down.
Everything works fine in normal startup. Device Manager shows that XP uses 2 drivers for my logitec mouse in %\system32\Drivers\mouclass.sys, & sermouse.sys
is BOOT.INI refusing to load those 2 logitec drivers in Safe Mode?
How can i modify BOOT.INI to include mouse drivers? Is that possible at all?

Thanks Proffitt, but the logitec mouse is cable connected to PS/2 port. (NOT wireless)
Also, remember it works fine in normal startup but i certainly want it to work in Safe Mode incase something goes kaput.
How can i tell if BOOT.INI loads the mouse drivers in safe mode? And what commands should i add to boot.ini to make it work?

My Logitech Wheel Mouse on PS/2 works fine in all modes.

But I didn't load ANY Logitech software since it wasn't required. You may have to talk to Logitech on how to uninstall said drivers?

Or try the Add/Remove Software, or the remove driver feature in the Device Manager?

You're quite rigt Bob, all windows versions up to xp identifies this logitec mouse without requiring any additional drivers.
The 2 drivers i found from Device Manager - mouclass.sys & sermouse.sys - are xp's native drivers which it uses to run the mouse. I didn't install it.
I only brought it to the attention of the technical staff to know which drivers xp is using for my mouse. But i didn't manually install it.
If all other PS/2 mice work well in safe mode, does it mean xp don't like the logitec i'm using?

The :XP won't let you use THAT mouse in Safe Mode
by R. Proffitt Forum moderator / November 4, 2003 10:24 AM PST

There are a few out there like that.

I don't know of a cure since I don't keep such mice around for long.

"Three blind mice
Three blind mice
See how they run
See how they run

They all ran after
The farmer's wife
She cut off their tails
With a carving knife
Did you ever see
Such a sight in your life
As three blind mice?"

Thanks greatly.

I agree with Bob- could be THAT mouse- (or Logitech in general...)
by Brandon Eng / November 4, 2003 11:03 AM PST

I've seen plenty of problems regarding Logitech mice and keyboards. Like Bob, when I did use a Logitech mouse and keyboard, I let XP load the drivers. Still, I've seen people with problems such as yours when you haven't loaded any Logitech drivers. Could be that XP and Logitech simply don't get along on certain systems? Or MS screwed up somehow (surprise, surprise)?

The Logitech story is a twisted one. For most of their product line of mice and keyboards, the OS's just work fine (there are exceptions!)

But what happens is that the extra 20 keys on a keyboard may do nothing which is fine by me compared to an issue where Logitech feigned a 'nothing wrong we know about' in which no amount of system cajoling would bring back the XP OS. Eventually a method of reverting to the stock OS drivers was provided, but what a headache.

I can't write I don't like the Logitech hardware. Now that we are into optical mice the issues with the old roller ball mice seem to have faded away.

My advice is simple. Try the device without the Logitech drivers. REALLY TRY to make do without the Logitech drivers since they repeatedly have stubbed their toe over this too many times.

Of course, my view on this may be skewed. People only bring me the failures.
