Zippy WK610 (USB) does not work through KVM switch
I just received my new keyboard (see subject line for details), it is the USB version.
I have the following problem and could use your advise.
At home I have my PC's connected through a KVM switch.
Since the KVM switch has PS/2 connections for the keyboard and mouse, I use PS/2 to USB adapters for each.
Unfortunately the keyboard does not seem to work through the KVM switch, but it does work when plugged into a PC directly.
Any advise as to what this could be caused by is much appreciated.
I've got the same problem with a Microsoft keyboard. Works plugged into the computer via USB, but not into my KVM switch through USB to PS/2 adapters. Old keyboard works fine (I'm typing this with it), but not the new one, so it isn't the connection. Thanks

Could be either a short in the Keyboard or it is not USB adapter compatible, some mice are like this. Plug it into a computer with PS2 port and see if it still malfunctions, if it does then the keyboard has a short, if not, it is incompatible with a USB adapter. Keyboards send two codes whenever a key is pressed, one for the key itself and one to let the computer know it the Shift/Ctrl/Alt keys are being pressed.
The GCS632U has keyboard and mouse emulation that may not work with all wireless combos. If your wireless combo is going to work the single USB connection would need to go into the keyboard port as that is the only port that will recognize the hot key switching commands. If the wireless combo still has problems then try using a USB wired keyboard to ensure the GCS632U is working correctly.
Hi ther. make sure that you connect them to the correct port. If using a wireless keyboard, connect the receiver to the keyboard port. check underneath for the keyboard icon. Make sure that the receiver is connected to that port.
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.
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.
Operating System doesn't deal anything on your problem. The problem depends on the brand of you computers or the type of keyboard you are using.
The GCS632U is designed to work with standard USB keyboard and mouse only. And wireless and gaming keyboards and mice are not guaranteed to work correctly with this KVM switch. If any one of you is using the new Mac Aluminum keyboard, this keyboard will not work with the older version of the GCS632U. But IOGEAR releases a new batch of GCS632U that would work with the Apple Aluminum keyboard.
If you have an Apple Aluminum keyboard that does not work with the GCS632U, you may contact the IOGEAR Tech support and they will process a Return Merchandize Authorization (RMA) if your device is still under the warranty period.
To resolve your keyboard issue, try to power cycle the KVM switch by disconnecting it from the computers, disconnect also the keyboard and mouse from the KVM switch. Leave it disconnected for two minutes. After two minutes, reconnect everything and reboot the computers.
The MS keyboard & mouse receiver is effectively a USB hub with two devices connected to it. So, plugging it into the keyboard socket on the KVM switch may well work, depending on how that particular switch implements USB. If it just passes things through, it should be OK. On the PC side you should only need to plug in the USB cable from the switch's keyboard port.
Are you sure, the usb cable belonging to the keyboard is plugged in the appropriate slot?
I have a wireless keyboard/mouse, so I have only 1 usb cable going into the switch. The first time, is plugged it into the slot of the mouse, and the switch did not work, so I plugged the cable in the other slot, and now everything works properly.
