Mouse not working properly with kvm 221 - D-Link KVM-221 (DHKVM221) 2-port KVM Switch

D-Link KVM's have a shortcut for "resetting" keyboard+mouse.

Hold down Scroll Lock and press M

If that does not help, try unplugging mouse and keyboard for 3 seconds then plugging them in again.

Unplug all the cables and replug them in. This is a fine kvm switch and should work properly for all almost all configurations.

the GCS632U has keyboard and mouse emulation that may not function correctly with docking stations. To ensure the KVM it self is working correctly I would suggest plugging the single USB from the KVM directly into the laptop and see if you have the same keyboard problem. This will at least tell you if the KVM is working properly or not.

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!

Try this:
1. Disconnect your HP computer, so that only the MSI Wind is connected.
2. On the keyboard, hit [Numlock]+[-] then press [A] (this will auto-search for the computer that's connected, and connect both keyboard and mouse to that port).

Give XP a minute to detect new hardware. If XP does not detect the mouse, try plugging the mouse into a port directly on your netbook. If XP still does not detect the mouse, it's XP that's not detecting your mouse properly, not the kvm switch. :) If it does detect it, you should be able to then plug it back into your kvm switch and it should work at that point.
Note: if you get stuck with lights flashing on your keyboard, just hit [Esc] on the keyboard. That will reset the KVM switch.
Hope this helps!

Most KVM switches does not have a driver. Because these devices are simply Plug-n-Play and does not require any driver installation.

What you need to do is to check the system requirements for every KVM switches before purchasing it.

Here's the fact:
- PS/2 KVM switches are designed for PS/2 computers keyboard and mouse

- USB KVM switches are designed to work with USB. Meaning, if you're going to use an adapter (PS/2 to USB), there's a big chance that your KVM might not work correctly.

- Most KVM switches does not work properly with docking stations.

- KVM switches are tested to work with wired keyboards and mice.

- You have to make sure that everything is properly connected to the computers if you want your KVM switch function properly.

- Lastly, update the USB driver of your computers (XP and Vista).

- Most KVMs has a firmware upgrade that you may find in manufacturer's Web site.

The GCS634U is designed and tested to work only with a standard USB keyboard and mouse. However, most wireless keyboards and mice work with it, but they cannot guarantee any specific model or brand that would work correctly.

As you can see, this KVM switch is a bus powered device (meaning it only gets power from the USB ports of the computers). If the computer cannot provide enough power for the KVM switch to function correctly, then the wireless keyboard will be affected.

You may try using the IOGEAR GKM541RA. It's tested to work with the GCS634U. Or you may also try using a self-powered USB hub (meaning, it has it's own power adapter) and connect it in between the KVM switch and the computer. That self-powered USB hub will be the one that will add up power to the KVM switch and help it to function properly.

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.

Try and use only USB or only PS2 mouse for the same.

Does a mouse work if plugged directly into the laptop? Sometimes you have to change a laptop in the BIOS to allow a PS2 mouse in addition or instead of the touchpad. It may not be recognizing the KVM as a mouse. Try plugging the mouse right into the laptop and see if that works.
