Kvm switch keyboard not working

I've been dealing with the weirdest glitch ever. The other 3 computers next to it do not have that issue. Have tried installing Windows 7 and XP, and both do the same, suddenly ti will say that the USB device cannot be started and drop them. Weirdest thing is there is another station with a setup exactly like it, but it does not present that glitch. The only other difference was that on the 'good' station they use admin rights for everything; so I granted admin rights to the 'bad' desktop, and although that has slowed the issue a bit, it's still doing it.

Then I figured it could be the motherboard; so replaced the motherboard with a brand new one, same model and all, Intel DH55PJ with an iCore5.

I'm not sure exactly why the issue occurs, but I know that part of the problem has to do with how the KVM switch works. As far as USB kvm switches go, they are built in a few different ways. The one you have uses a hub-based structure. This is why you hear the sound when switching to or from the computer, signifying the USB reconnecting or disconnecting. The USB Hub-type switch has it's benefits, because all devices are seen by the computer exactly as what they are. Another type of KVM switch uses emulation technology.

That means the OS doesn't know exactly what your devices are, it just considers them to be generic devices. Special functions, like volume controls, etc. Sometimes this may work fine for your needs, and it's fast and reliable. The other type uses Dynamic Device Mapping, or some similar technology.

What we think we know and dont know about tdcs

This one maps your specific keyboard and mouse to each connected system. This is kind of the best of both worlds, because the computers see your keyboard and mouse for exactly what they are - it doesn't use a generic profile.

Connectpro has the kvm switches with dynamic device mapping - and that should provide the stability needed, since your computer wouldn't have to re-detect those devices every time you switched ports. It is a thing! Although the listing says connect 2 laptops if you are using USB-C to dock both devices then it should just work. Two things to do here. Firstly speak to the software vendor to see what their roadmap is to making this software W10 compatible.

Secondly, is it currently running on W7 compatible hardwarehave you tried to P2V then run it as VM? Thanks for your comment. We haven't used a restore point, as the computer will do it on a fresh install of the OS either Win7 or XP.

kvm switch keyboard not working

This was a brand new out of the box computer, with fresh install of everything, and it was working fine while installing software on it, but then with the KVM it's not going well at all. Now every day I have to remote in to that desktop to save their documents when the mouse and keyboard stop responding, restart the computer, and that will keep them going for a few more hours again. No signs of anything funny on event viewer apps or system either, other then it saying it could not load the USB device which was using just a minute before without a problem This also might be pointless since it seems you have done a pretty good amount of troubleshooting, but If you go into the device manager and scroll down to USB Controllers, have you tried updating the drivers manually in there?As prices drop and new wireless technologies are developed, wireless keyboards and mice are becoming more and more common in home and business environments.

Unfortunately, due to the differences in the way in which wireless devices communicate, choosing the best KVM Switch for using a wireless keyboard and mouse can be daunting.

Beyond compatibility issues, very few KVM switches on the market explicitly state support for wireless devices making selecting your switching infrastructure difficult.

Asterisk commands

There are two main types of KVM Switches that can support controlling sources with a wireless keyboard and mouse. While neither KVM type guarantees support for wireless devices, the underlying technologies theoretically allow you to use them.

These ports let you transparently plug in and switch USB devices between connected computers. These KVMs often support Wireless devices with some extra configuration. While this Emulation is typically desired, it can interfere with Wireless devices. Some low-cost KVMs still ship without Emulation, and some other models let you toggle this feature in settings. Please Note Unless a manufacturer states explicit support for a Wireless Keyboard and Mouse model, we are unable to guarantee compatibility in a specific environment.

In order to support Hot-Key operation and uninterrupted keyboard-mouse function while switching, most KVM Switches have a chip that constantly buffers reads signals from the keyboard and mouse, and transfers any button presses to the connected computer.

While this emulation works great for wired devices, wireless devices use a different data transfer protocol that is not compatible. This is the main cause of problems when using wireless devices on a KVM, as the KVM switch will only relay signals that it understands to the computer.

Though on some occasions wireless combos will function on a KVM switch that uses emulation, this is highly unusual and is entirely dependent on the user environment. If you are currently attempting to use a wireless device on a KVM, or have your mind set on a KVM that uses emulation, there are a few options that may make your wireless devices function properly.

Response delay after subsequent switches usually takes sec. Unless a manufacturer states explicit support for a Wireless Keyboard and Mouse model, we are unable to guarantee compatibility in a specific environment.

How to use a Gaming Keyboard with a KVM Switch

While 'Emulated USB' is typically the root problem, there are various other factors that may cause issues. There is no de-facto standard when choosing a KVM switch for use with wireless devices, however the following is a general list of things to keep in mind when choosing the appropriate KVM:. Customers Include. Plug the wireless USB combo receiver I.

If this doesn't work, try to plug-in the wireless receiver into the mouse port, and a separate wired keyboard into the keyboard USB port - you can put this keyboard aside and use the wireless devices instead. Some KVMs require a wired keyboard to be connected to the KVMs regular keyboard USB port to function - you can put this keyboard aside and use the wireless devices instead. Un-install the driver for the wireless device. Sometimes the proprietary driver for a wireless device can interfere with a KVM, and compatibility issues can be solved by using the native driver included in the OS instead.

Slight voltage fluctuations may disconnect your wireless devices occasionally, especially while idling or switching. There isn't much to do about this, but typically we have seen better results with higher quality KVM devices.

Thread starter donsor Start date May 22, Status This thread has been Locked and is not open to further replies.

Please start a New Thread if you're having a similar issue. View our Welcome Guide to learn how to use this site. Joined Jul 11, Messages My mouse is a Logitech Invisible Wireless mouse. My problem is that often when connected to the KVM switch all inputs and outputs work except the keyboard and the mouse. The port indicator selector light which normally is ON steady is now flashing.

There is nothing wrong with the mouse or the keyboard because when connected directly to either PC they work. My question is: Is there a compatibility issue with certain keyboard and mouse models when used with KVM switches, by this I mean that some keyboards particularly gaming keyboards and mice may require more power and the KVM USB circuit has power limitation.

Frank: I have a wired keyboard and a wireless mouse. I replaced the wireless mouse with a wired USB mouse but the problem still persisted. After talking to one of their techs, as I suspected it was my gaming keyboard that was causing the problem.

The tech said he had experienced similar problems. Apparently some gaming keyboards, but not all, are a bit more power demanding which affects the performance of the USB circuit in the KVM switch. The solution is if I am to keep my gaming keyboard is to buy a higher quality KVM switch costing over a hundred bucks. What to do what to do. Can't have it all. It sounds like you need a more expensive model that's electrically powered.Keep in touch and stay productive with Teams and Officeeven when you're working remotely.

kvm switch keyboard not working

Did you ever figure out your issue? I had this problem affect a laptop after an update some time back. Shortly after I found some servers also had applied some updates and the same issue started happening. Now, none of my systems work on the switch. This was all post a system receiving an update. I am highly confident that functionally nothing has changed with the switch itself, it is still operating nominally.

If I'm sitting at an unused port, I can use the keyboard to select a new port no problem. If that port contains an affected system, the keyboard no longer responds and I need to manually switch it.

I have the same question Error Problem with your gaming keyboard and kvm switch? Gaming Keyboard not working right with kvm?

Read below! I could use the manual buttons on the front of the KVM, but that is incredibly lame. I needed to upgrade my KVM switch as well. It was all PS2. And, obviously, I needed a USB keyboard. I caught a comment on Newegg, stating it had to be connected to a powered hub, and to plug the hub into the mouse port of the KVM.

It is now AM. What is funny is the G works in the bios, but as soon as you get to windows 7, it is dead. The KVM switch, obviously, is more important than the fancy keyboard. When I have time and money on the table with paying customers, the KVM switch stays. I slpurged for this keyboard.

There was another one on TigerDirect, much cheaper, and with backlighting, That probably would have worked. Now I have to RMA this keyboard, and pay for the return shipping. For crying out loud, this is the later half of Chris Pate lines this out below. It is unlikely that the extended functionality of the G G-Keys, audio jacks, programmable backlighting colors will function on any KVM that does not support the G The only way for these features to function through a KVM is for the KVM manufacturer to design their product to support the extended feature set of the keyboard.

Most KVM switches do not work as passthrough devices. In order to prevent the host PC from going through a full enumeration cycle every time the user switches between them or to prevent the PC from hanging on boot due to the BIOS not detecting the presence of a keyboardthe KVM declares itself to the host system to be a keyboard and a mouse.

In effect, the KVM is a small computer that receives input from the attached keyboard and mouse, and then forwards that information directly to the host PC. Testing results to come…. The switch was to dumb to release the keyboard since it thought it was in use all the time because of the LCD manager and all the other features running in the background. The peripheral ports a designed to be used with other USB devices such as external hard, printers or scanners.

If there was emulation on the peripheral ports then these types of USB devices would not function. At this time we have not heard about any type of update that would allow keyboard switching through the peripheral ports or being able to turn completely turn the emulation off.

That said I think this is probably the best choice for most people. So what did I do? I plugged one USB connection into the keyboard emulation port of theand one into the peripheral port of the Your email address will not be published. I found myself in a similar situation to Stubbs.When connected directly to the laptop no port replicator or monitor stand the setup works great. When connected to the Port Replicator, the mouse works - but keyboard does not. I've loaded the latest NSS software download dated with no improvement.

I'm operating on Windows v5. Does the keyboard work when it is directly attached? If so, then the hardware is working. I believe the problem may be with the compatibility of the KVM and the port replicator.

You should contact IOGear to find out how to make the signal stronger between the keyboard and the port replicator when the KVM is in use. It also works fine when connected directly to the back of the D This seems to indicate that the problem is related to the Dell port replicator. I've loaded the new NSS, but it didn't seem to help maybe created new problems read on. On the advice of another posting, I added a powered USB 2.

This has given mixed results. As long as you "wiggle" the mouse when returning to the D from time on the Toshiba it appears to work. Coincidentally, my D has become quite unstable today - graphic problems, lockups, etc.

I remain very unsatisfied. It's especially revolting when I have experienced absolutely no troubles with the Toshiba setup - and that machine is several years older and has less memory.

They seem to work better. The USB had different intermittent issues. Both have had new software released to fix some of the problems you are having.

The only rare problem is if i let the D go to standby on return sometimes the PS2 mouse don't work. So i don't use standby. I am going to update the software and is if it fixes my standby problem also.

It now has the mouse problem dead mouse every time i resume from standby but only when docked and using the PS2 mouse via KVM. With the Alps A00 driver it would only not work ever now and then. With the A07 driver it never works.

It turns out that even though the D is docked and the lid is closed when the PC comes out of standby it sets up the tpuchpad and don't see the PS2 mouse on the Docking station.
