DLINK KVM-221 switch not working with MS Laser Desktop 3000

The switch has two usb inputs, one for a mouse the other for a keyboard (although it doesn't really seem to matter which gets connected to which input). This works fine sharing with two computers using a separate mouse and separate keyboard but know I have a Microsoft wirless keyboard+mouse. They talk to a receiver which has one USB output and no matter which port I plug it into on the KVM the systems do not see the mouse. They both get the keyboard fine (again regardless of which KVM port I plug the Microsoft receiver into) but nothing happens with the mouse. Plugging the receiver directly into either system works fine with both keyboard and mouse detected properly... I really don't want to give up the wireless desktop but I need a working KVM.... help!?

    D-Link KVM 221

    The switch has 2 USB ports, one for Keyboard, one for mouse.

    I have wireless mouse and kb, and only one USB receptor that controls both.

    When I plug it into the switch, only the keyboard works.

Hi,

I got this problem also; the caplock indicator didn't even lit. The problem is current consumption. KVM switch, keyboard (250mA) and mouse (100mA) were draining too much current. I changed the keyboard for a 100mA and it worked.

I hope this can help other people...

Wireless keyboard and mouse works fine with computer but when I attempt to use it on the f1dh104l switch it does not recognize the mouse or keyboard. it is a dell e6400 laptop that i'm attempting to...


the problem is that most Wireless Keyboard and Mice combos use Composite USB, the KVM however is expecting one signal on each entry port (one for mouse, and one for Keyboard).

replace yoru wireless Combo for a standard Keyboard and Mouse to make this work.

A work around would be using a MS Wireless Mouse and a different brand of Wireless Keyboard using both Wireless receivers and plug them into different ports on the KVM

I have a Trendnet TK-209 KVM switch. My keyboard and mouse (MS wireless) that worked well for a year stopped working through the switch. they work well if connected directly to each computer.


I can confirm the same problem happened with me just now. I have TrendNet USB/KVM TK-207 and was flawlessly working with Logitech K260 Wireless Mouse and Keyboard Combo, but today on both computers all I can see is the error:

.
USB Device not recognized - The last USB device you connected to this computer malfunctioned and Windows does not recognize it.

I unplugged the usb wireless adapter and connected it directly to the PC - it worked like a charm again. I have tried to connect the wireless adapter to the mouse port hoping that the keyboard USB port is causing problems, but all I got was the same error. I have tried to conect a normal USB keyboard, but again the same error I get for both - the mouse and keyboard, so it is more than obvious now that the USB ports of my KVN Switch are malfunctioning. I will try to leave it for a while if it got hot somehow as it was connected for more than 6 months working perfectly fine, but if not, I am heading to the store for support/replacement.

I just bought d-link kvm-221... switching two pc's in a single monitor is working fine but the problem is my keyboard and mouse are not working (didn't detect by kvm-221).


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.

Keyboard not working on one side of switch


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.

Hi . .. I want to use this KVM switch to connect


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.

4-port usb kvw switch #GCS634U


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.

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.

USB mouse not recognized


I have similar problem. 2 inland KVM's (both have PS2 inputs, one has USB outputs) do not light or recognize my usb mouse with a PS2 adapter. They do recognize a PS2 ball mouse on the KVM's however. One of the computers (Sony vaio 1.5 GHz) does recognize a usb mouse with adapter on 2 other KVM's (Old Belkin and a Trendnet) (the second computer I have not tried in those configurations). Next I will try an optical mouse with a PS2 fitting. That did work with a fifth KVM at an auto business last week.

KVM GCS1734 with microsoft wireless mouse/keybrd 4000


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.

Micrsosoft optical desktop 1000 to Belkin KVM switch


This is a common problem with a number of KVM switches - this model in particular. I have heard that the Bytecc BT-2000 connector will work in SOME cases: *5.99 on Newegg - http://www.newegg.com/Product/Product.aspx?Item=N82E16812101117 It might be worth the investment to give it a try, if you haven't already tried this. Bytecc does make very high quality hardware. However, if that doesn't work, there's really not much else that can be done, other than replacing the KVM with one designed to run off a single USB port. Hate giving bad news like that. It's a hardware limitation, I'm afraid.
