    Desktop or laptop? were they working before? did you make any recent changes to software or device manager, etc? have you made any recent changes inside your computers case like added new hardware, dropped it, etc?

Try reinstalling the chipset drivers from

Select the Operating system
The Category as Chipset
Importance should be All
Click on the Intel driver
Download now
File name is R132539.EXE

If this does not work you will be having 2 usb at the back and in the front of the system.IF the back does not work than you need to get a local tech out at your place as it is a problem with the USB controller on the motherboard and that might have to be replced .If it is the front USB (Only if you have them) then there is a cable coming from the USB controller to the fromnt usb ports that cable might have got unplugged for that you need to open the tower.But i would still recommend a local tech.

Shut down the computer, disconnect ALL USB connections front and back.
  1. Plug in just the keyboard USB cable and start the computer. If it does not work, try moving the USB plug for the keyboard and trying again. If you can't find ANY USB port that works, then your motherboard is probably fried.
  2. Once the computer comes up with just the keyboard, plug in the mouse and wait for it to work (should be almost immediately). If it does not work in one USB port,try another until it works... wait several seconds after plugging it in before deciding whether it works or not.
  3. Once you have a working keyboard and mouse, begin plugging in any other USB devices, one at a time and verifying that each device works. As with the keyboard and mouse, if it does not work in one port, try another.
    1. Note that some devices may take several seconds or up to a minute to fully be discovered and set up and you may have to respond to something on the screen.

Keyboard will not work. I shut off computer and removed mouse and keyboard and turned back on replacing the mouse and then the keyboard. Computer beeps (acknowledging the keyboard) but I can not type?...

If the keyboard is USB, and I am assuming it is, try plugging it into a different USB port and allow a minute for the drivers to install automatically.

If the keyboard is PS2 (round purple connector), make sure you have it plugged in BEFORE you turn the computer on, or it won't work.

If neither of these work, try a different keyboard; if that works, the keyboard needs to go.

Good luck!

Well the first thing to do, is swap out the "Old" mouse for a "Know Good" one.. Thats the only real way to know if the mouse or software thats the problem. If BOTH do not work. Then try this. 1. Go to Start>> Right click My Computer>> Manage>> Device Manager 2. Expand the USB Controller section 3. Right click and Uninstall all of the listed USB devices 4. Reboot the system Try the Mouse again. if still no go, you may have a Virus, or your system is scrambled, you could try a System Restore.

Brought a CS62US and Mircosoft KB with mouse. When USB combo plugged on the left USB, only KB is worked together with switching function. When USB combo plugged on the rigth USB, both KB & Mouse worked...

Unfortunately, this switch has a dedicated port for keyboard that listens for the keyboard keystroke. You MUST plug the keyboard into the dedicated keyboard port on the KVM switch for the hotkeys to work. I recommend putting the mouse that comes with your keyboard to the side, and using another mouse, plugged into the dedicated mouse USB port on the switch. Not the prettiest solution, but some of those mouse/keyboard combos have some funky hardware!

I just did a system restore, and now the keyboard or the mouse is working

It *IS* working? So, what's the problem?

Is the keyboard jack plugged into the keyboard socket? not the mouse socket?

Is the keyboard jack plugged in to a USB port?
