1 Answer

A USB mouse will work but the PS/2 mouse failed. What causes it?

There are only two(2) USB port available on board and the system is prompting me to use the other high speed USB port available on board. Will an external 2 port USB do? What connector will i use to connect the ext USB ports to the board? I checked for a loose connection on PS/2 but found none. Updating driver also did not work as the system refuse to. No problem with the PS/2 keyboard. Thanks

Re: A USB mouse will work but the PS/2 mouse failed. What...

Hi melch, On the PS/2 mouse, chances are that the surface mounted fusible link/resistor supplying the +5VDC is open. It is normally very near the PS/2 port and marked [0] or labeled F???. This can be verified by measuring the absence/presence of +5 at pin 4 of the connector. In some cases, it is the I/O chip that gets damaged. Re "only two(2)USB port" aside from the 2 rear USB ports, the Asus CUV4X-C has another pair of USB connectors that are normally connected to the front panel of the casing. It is located very near the motherboard battery. Re "...prompting...high speed USB port...", normally by updating your OS (say XP to SP2) or downloading/installing latest VIA 4 in 1 Drivers should make your USB 2.0 compatible. Hope this be of some help/idea. Pls post back how things turned up or should you need further information. Good luck and kind regards.

Try the keyboard and mouse on anothe system. if it works fine the on board PS2 port is most likely bad. Buy a USB keyboard and mouse in plalace of the PS2 keybaord and mouse or change the motherbord. If the keyboard and mouse is bad replace with a good one.

Upgrade to windows 7 caused a heap of problems

Have you tried other USB mouse?

It might just be a problem with your USB mouse, the other thing is you can also try plugging-in USB devices on your USB ports to test them like (USB flash drives)

You can also try to use PS/2 mouse to check if the problem is really the ports.

With regards to the drivers

It seems like you need to download those.

Because even you downgraded your system to XP, still the OS needs the driver for them.

YOu can try to open up your CPU
then reseat the cables for the DVD drives.

PS/2 mouse port not working?

Hello fredbeer,

Besides the obvious checking with your device manager, you can download a port test kit HERE. That will be able to test if it's working. The other thing you can do is switch the keyboard into the mouse port and the mouse into the keyboard port. You should get some errors, if not, one of them will work and the other won't. Hopefully, you'll get the keyboard in the mouse port to work, so you know the port is working. Also, if you have any other PS2 devices that you can test it with.

Good Luck and don't forget to leave a rating based on my solution.

Mainboard does not recognize the PS/2 mouse

Sounds like the serial port died. I have seen that happen before. You could try a DB9 to PS/2 adapter or DB9 to USB. The DB9 to PS/2 is cheaper of the 2.

Hope this helps.

that means you didnot clone the system yourself and it will be difficult for you to fix it. so get USB mouse and keyboard. thats the only solution for now unless you can talk it to a qualified repairer in your area.

Ps/2 keyboard port not working

Slim, Other than saying well it was a good couple years for the board lets just verify: Have you tried a different keyboard? Check device manager and see if you uninstall the keyboard and then reinstall it. Or have you recently installed any new devices that may have taken the resources away from the keyboard plug? If not get a usb keyboard and make sure you info is backed up...just in case. Good Luck, Tim
