Question about D-Link DKVM 2K (DKVM-2K) 2-port KVM Switch

Mouse and keyboard not recognized on second computer

I'm using the kvm switch with two computers running Windows XP Pro. The switch works only if computer 1 is turned on before computer 2. If I turn on only computer 2, neither the keyboard nor mouse work. If I turn on 1, then 2, and turn off one after 2 has booted, then the mouse and keyboard work.

If I unplug computer 1 from the kvm switch, I still have no keyboard or mouse on 2.

If I plug the mouse, keyboard and monitor directly into computer 2, everything works fine.

Reversing the kvm plugs on computers 1 and 2 makes no difference to the above problem.

    I have the same problem. Computer 1 is a multiboot system: WinXP, Win98, DOS and several Linux. The problem occurs only when WinXP is booted first after power on. Computer 2 has no XP, so there is no problem.
    I ususally use Linux and occasionally boot WinXP after, then there is no problem. When I want to to WinXP directly, I boot DOS first (takes only seconds).
    I think it's not necessary to boot both computers in order to work around the problem. Try to boot another system before XP (e.g. DOS or Linux from diskette or CD) or create a small (stripped down) DOS, Win98 or Linux partition and boot this before booting XP.
    Exchanging computer 1 and 2 does not change the problem.

Try hitting the following keys in succession and your KVM should reset the keyboard and mouse interface and allow them to work:

Scroll Lock + Scroll Lock + End

I have a solution for this problem which I posted previously:
"I'm using the kvm switch with two computers running Windows XP Pro. The switch works only if computer 1 is turned on before computer 2. If I turn on only computer 2, neither the keyboard nor mouse work. If I turn on 1, then 2, and turn off one after 2 has booted, then the mouse and keyboard work.

If I unplug computer 1 from the kvm switch, I still have no keyboard or mouse on 2.

If I plug the mouse, keyboard and monitor directly into computer 2, everything works fine.

Reversing the kvm plugs on computers 1 and 2 makes no difference to the above problem."

SOLUTION: I turn on computer 2 and THEN computer 1. Computer 2 displays the CapLock and ScrollLock and then the NumLock lights. When the NumLock lightis on, I press the Numlock key to turn the light off, and then I shut down computer 2. Then computer 1 boots with access to the mouse, keyboard, and monitor.

Solution for the mouse. I have 8 KVM's. Most of my computers work with the KVMs. On 1 inland KVM the logitect and Microsoft optical mice do not work on one computer (but work with the other computers). They both are USB. I hook them up with a USB to PS2 adapter. If I use a ps2 ball mouse connected to the KVM the mouse works. All the Mice work if I directly connect them. Since I do not want a ball mouse I got a Frisby optical PS2 mouse. It works with all the computers on the KVM's.

I do not have a solution for the Keyboard yet. 1 computer (ASUS MB) on my trendnet or belkin 4 postion KVM does not recognize the keyboard.

Sounds like KVM has a bug. Maybe their website has a fix.

I have iogear miniview kvm (gcs62) keyboard works but mouse conn does not. Mluse is usb mouse with ps/2 adapter. Direct connection via usb works. used to also work with adapter but having tried it with kvm...


USB mouse with PS/2 adapter is not guaranteed to wok with GCS62. This KVM switch is designed to work with PS/2 keyboards and mice only.

When the USB mouse with PS/2 adapter is used in a computer directly, it will surely work, because the USB port can give enough power for the mouse to work. And it can easily convert the signal.

Unlike in KVM switch, the switch serves as a bridge between the mouse and the computer. And the computer does not easily recognize the mouse.

I would suggest to use a regular PS/2 mouse. Or if you want to use USB keyboard and mouse, you need to have a USB KVM switch. Model GCS632U.

Thank you and good luck!

I have a kvm switch vista lap and xp desktop stopped working


I've gone through alot of KVM switches. Something in the electronics just gives up. If your keyboard and mouse are the pci type (round connector) then don't switch their locations while the computers are on. Windows won't see the change and you may damage the system. If thy're USB type then switching is OK.

All Keys do not work on keyboard with KVM switch


GCS632U is designed to work with standard USB keyboard an mouse only. You have to make sure that you are not using any type of adapter such as PS/2 to USB adapter. To further isolate the problem, please follow the steps below:

1. Connect the USB keybord directly to th computer to make sure that the keyboard is working properly.

2. Make sure that the keyboard is connected to the keyboard port on your KVM switch. You may take a look under neath this GCS632U (near the USB ports) and you will see an icon where to connect the keyboar and mouse.

3. If you're still gettings the same problem, Try power cycling this kvm switch by disconnecting if from the computers and disconnect also the keyboard and mouse from the KVM switch and leave them disconnected for a minute or two.

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

5. If same problem exist, try using different USB keyboard.

NOTE: This KVM swith does not work correctly with wireless, gaming and smart keyboards because it's designed to work with standrd USB keyboard only.

Problem with KVM switch and Vista


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.

KVM converter


Buy a usb hub and an usb extension, so that you can have 4 or 6 free usb at the front of your computer, and you can switch devices using usb rather then the mouse converter . Using the converter on mouse and keybord make easier for the plugs to slip out, and usb is better. Note some usb modem and some other device do not support usb hubs, you have to plug them straight into the free computer plug , if you have any.

Belkin KVM STandard 9 pin mouse/keyboard to USB COnversion


You need to have the keyboard connecter (purple) connected to your computer in order for the KVM switch to recognize it. The computer is providing some power through the keyboard connector and this is what the KVM switch is feeding on.

If you have a USB keyboard, you may want to change your KVM for a USB compatible one. If you just want to use the KVM to switch your monitor, you may plug the keyboard (purple) connector of the KVM to your computer's keyboard PS/2 port and also connect you USB keyboard directly to your computer. It should work.

KVM freeze, mouse and keyboard failure upon keypress


When ever trouble shooting a KVM that has a problem with one computer always swap the cables at the computer end -- that will tell you if you have a computer or KVM issue.
