Erratic Mouse and Keyboard with KVM -- newly replaced computer
Hi -- I have a KVM problem. I introduced a new computeer to a working KVM setup and the following occurs: Computer 2: everything A OK Computer 1 (new): This unit has no PS2 ports for mouse or keyboard. I have an adapter that has PS2 connectors coming off of a USB connection. I have used this adapter (for this same computer) with a standard keyboard and mouse with great success. BUT when I plug the keyboard & mouse into the KVM and the KVM connectors into this USB adapter, the mouse and keyboard go absolutely haywire. One keystoke will be repeated indefinitely. The mouse clicks indiscriminately and often.
If I start on Computer 2, the mouse and keyboard behave normally.
The KVM is a Linksys ProConnect 2-port KVM switch.

I would look first at rep;lacing the cable itself, KVM's usually last a very long time. Cables can break down after awhile. The easiest way to check is to try the other cable on the new machine., or a pin could be bent on the cable. I would look at those two things first before the KVM. IT is possible that the KVM may not support the new machine, depending on how old it is.
This is a common problem with KVM switches. To isolate the problem, here's what you need to do:
1. First, connect the keyboard and mouse directly to the problem
computer to ensure that the keyboard and mouse works correctly while
being directly connected.
2. Swap the connection of two computers. If you're having a problem on
the computer that is connected to port 1 of the KVM, connect that
computer to port 2 of the switch or just swap the connection. If the
problem recur on port 1, then there's a problem with the keyboard and
mouse cable on port 1.
3. But if you're not able to duplicate the problem on port 1 or 2,
disconnect the KVM switch from the computers, leave it disconnected for
4. After 5 minutes, reconnect the KVM to the computers and reboot the computers.
5. If same problem occur, then contact the manufacturer of the KVM and have them RMA the device.
The GCS632U is just one KVM switch. But if you're going to check it out,
it has actually two separate connections.
It will just switch
once you toggle from one computer to another.
Try to power cycle
the KVM switch.
1. Shut off both computers. 2. Disconnect the
KVM switch from the computers. (make sure that not even a single cable
is connected to the computer, even the audio). 3. Leave it
disconnected for 10 minutes. 4. Reconnect the KVM and boot up the XP
first. 5. Boot up the Vista, try to toggle from one computer to
another. 6. LASTLY, shut off the Vista and see if same problem will
If you get the same problem, then you need to contact
IOGEAR and have them RMA the device. Because this is the first time that
I heard of this problem.
Check that you are getting power to your StarView SV211K 2-port KVM switch. Try disconnecting the power, and then reconnect it, to "reset" the KVM. Check all the cables from port #1 on the KVM to computer #1. Check all the cables from port #2 on the KVM to computer #2.
Check all the cables from your Keyboard/Video/Mouse to the KVM.
If you still have a problem, disconnect everything from the KVM,
and connect the Keyboard/Video/Mouse directly to computer #1,
to ensure that it works *without* involving the KVM.
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.
Try swapping the KVM cables from the 2008 computer into the Vista computer and see if the problem follows the 2008 computer. This KVM gets the drivers it needs from the OS and the IOGear web site does not show any support for 2008.
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.
If you have the PS2 mouse and keyboard (round plug-in) instead of USB this is an easy install. however if you have USB you will need adapters to make this work, but I do not recommend it since more problems could occur. If you have the PS2 ends first shutdown both computers. remove your monitor, mouse, and keyboard from your computer and attach them to the single end of the switch. Mouse goes to Green, Keyboard to Purple. Take the other ends and connect the first group to your first computer mouse, keyboard, and monitor (same colors as above) and repeat for 2nd group of wires on 2nd computer. turn the computers on. you should get display, keyboard, and mouse for 1st computer. after both boot hit scroll lock 2 times within 2 seconds and then arrow up or down key to change between computers.
Sadly, it is probably the KVM as this particular model has a string of failures and is only rated 2 out of 5 stars on Amazon due to poor performance. :(
What I would do first is plug in Computer 2 directly to the monitor, keyboard and mouse with no KVM. If those work fine, it is probably not a computer issue; if you don't get video here, then it is a seperate issue with that PC.
If Computer 2 is working, plug both computers into the KVM but switch the cables (plug Computer 1 into the KVM using Computer 2's cables). If Computer 2 shows up and can't switch to Computer 1, then it is the KVM messing up.
