Keyboard works, mouse does not

Unfortunately the wireless seems to have more problems than the corded type and the fault is normally in the sub processor IC. If you have checked the battery and seen that the voltage reached the IC then it is possible that the IC is faulty as it does not process or communicate.
Check the cost of the IC to a new keyboard.

Remove the battery of the keyboard and clean, test teh battery . If bad replace the battery and test. If the same fault occurs since the mouse is working fine then the keyboard has a fault.
It is possible that the keyboard processor is faulty . You must check if the cost of a new keyboard will be as much as changing the IC in the keyboard.

Might be a defective keyboard. Check and make sure its compatible for windows vista but all keyboards should work with any system.. As well maybe the port on the computer is bad..

Downloaded Setpoint at http://www.neowin.net/news/software/07/06/06/logitech-setpoint-400-vista-only. Worked perfectly.

This should solve your issue from keyboard not responding..

The usb ports might me malfunctioning . Try to use different ports. If that doesnt solve it then there might be a power issue on the board.

Your switch box will need auxiliary power.

Your problem has nothing to do with the Operating System (Vista), it has something to do with the brand of your computer. I have similar problem before, I have Vista (Dell), but the time I connected another Vista (Sony Vaio), everything worked correctly.

This is what you need to do:

1. You have to make sure that you are using a standard USB keyboard and mouse.

2. Connect first the keyboard and mouse directly to the Vista computer to see if the USB ports of your computer are working properly.

3. You may power cycle the KVM switch by disconnecting it from the computers (including the keyboard and mouse) and leave it disconnected for 2 minutes.

4. Reconnect everything after two minutes and then reboot the computers.

5. Try using different USB keyboard if problem exist after power cycling the KVM switch.

Gken, assuming your new mouse and keyboard are USB go into the BIOS of your PC and check if USB mouse and USB keyboard are enabled. If not, enable them, that would fix the problem.

kiratae, have you tried using XP drivers for that mouse? According to logitech the v220 is certified for vista, did you plug in the little USB receiver?

i reinstall all the driver of my vista laptop drive especially bios and restart my computer and this solve my problem.
