Re: Trust,,Optical USB Mouse MI-2900Z

Do you have the keyboard + mouse combo with iNav on the keyboard. I had the exact same problem, so I took a screwdriver to my keyboard and ripped out the iNav wheel from the keyboard, and hey - no more darsh random scrolling all the time. crude solution i know, but worked for me.

Use the drivers supplied. The lsmouse.exe must be running or it won't work.

Re: Trust,,Optical USB Mouse MI-2900Z

Are you using an optical mouse? I suggest that you have to provide a mousepad since the laser of the mouse will have a hard time to read on its surface especially if you are using glossy surface of your table.

trust me,it works!! =)

Mouse behaving erratically

1. uninstall the mouse and then reinstall the mouse by restarting the PC. Upon restart the mouse should be detected as new hardware and reinstall properly and this should correct the practice behavior of the mouse.
If not then you have a mouse with faulty electronics and needs replacement.

Pointer jumps

That's not a lot of information there...

How far does it jump? How often? Since when? Is this a new mouse, an old one, an optical or a ball mouse? Do you use a mouse pad? Have you installed any of that cursor mania stuff? Is it a USB mouse?

I'd recommend (If you have a ball mouse) to take out the ball by turning the circular plate under the mouse then blowing the dust out and wiping the ball clean. If it's an optical mouse i'd suggest a new mouse-pad designed especially for this optical mice. Also you might wanna try re-installing it. Or if it's a USB mouse trying it in a different slot and cleaning out that connection too.

USB mouse is jittery

Try the mouse on a different surface, also be sure you do not have any light directed at the mouse - this confuses the eye. Although no mouse pad is required for an optical mouse, sometimes it helps

Logitech Mouse V320 Corless Optical Mouse not working

The warrenty period is usually a year. Is there a connection button on the receiver as well? Normally you need to press the connect button on the mouse, and then on the receiver shortly there after. If you want to replace it, you might have an easier time just getting a new mouse.

Nonresponsive mi wireless optical mouse

make sure there are no power cables close to the mouse or receiver, I have seen this cause problems many times.

Also try pressing the connect button on the receiver then keep pressing the connect button on the mouse until the receiver light stops flashing

Mouse Problem

Possible solutions for this (and similar problems) include:
--Replace the batteries in your wireless mouse. If the connection strength is weak, wireless accessories have a tendancy to act up.
--Re-Install / update the mouse drivers. I'm unsure if Trust has drivers available for download from their website but it would be worth checking out if the first solution does not help fix the problem.

Normal 0 Try disconnecting the Mouse Receiver from the USB port and reinstall the CD software program. When the program asks you to connect the Mouse Receiver to the USB port, do so and it should work.
Hope this helps. Bud
