KVM freeze, mouse and keyboard failure upon keypress
The keyboard and mouse are wireless Logitech MX duo, using a USB to PS/2 converter to plug into KVM. Computer 2 (linux box) works just fine, Copmuter 1 (Windows box) will freeze whenever I push any buttons on the keyboard. By freeze, I mean that the keyboard and mouse will no longer respond and I have to reboot (albeit if I touch the keyboard again after it boots windows, I lose functionality again).
I have an ASUS PSP800, 1 gig of ram, Windows XP Pro, ATI Radeon 9800, Intel Pentium 4 3 ghz (overclocked to 3.3), SB Audigy 2.
I can't figure out why it doesn't like it on the windows box, but the linux box is just fine. Suggestions?

this is not uncommon. many kvm switches cannot work with those types of wireless mice. the reason for this is due to connection codes. these mice require a connection to secure the use with each computer. you can attempt to do this with your setpoint software. located in C:\Program Files\Logitech\SetPointP you will find the program CONNECT.EXE run this to redo your mouse connection. i will however inform you that even if this works there is a large chance that upon switching to the next pc the mouse wont work and you will need to repeat this process with each pc switch everytime you toggle pcs.
rule of thumb. if the mouse is wireless don't use it with a kvm.
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.
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.
When you say "traditional mouse and keyboard ports" i assume that you mean the green and purple PS/2 ports. If I am correct in my assumption then this is what you can do. You can buy PS/2 to USB converter for your mouse and keyboard. A simple google search should yield you plenty of shopping results. Just make sure that you buy PS/2 to USB converters, not USB to PS/2 converters or you'll probably get the wrong thing. Everything else should just be plug-n-play from there on out. Hope this helps.
Repeating keys? This is a common problem for KVM switches if you go beyond the devices' capability. As you can see, GCS62 is a PS/2 KVM switch and it was designed to work only using a regular PS/2 keyboard.
This KVM switch does not support PS/2 to USB adapter. It might work but it's not guaranteed to work correctly. This does not work properly if you have a docking station for the laptop. It might work for couple of months then it would stop.
You smay isolate the problem by following the steps below:
1. Connect the keyboard directly to the computer to see if you will get the same problem.
2. Power cycle the KVM switch by disconnecting it from the computers and leave it unplugged for a minute or two.
3. Avoid using hybrid connection (PS/2 converted to USB) only for testing purposes.
4. If that work, then you know the answer is that this KVM only designed an work correctly with native PS/2 connection.
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.
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.
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.
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.
