#REMOTE MOUSE NO COMPUTER DETECTED WINDOWS 7#
At the KVM switch momentarily disconnect USB B cable that's connected to the Windows 7 computer.ĭisconnection at this point is more convenient than at back of computer as KVM switch is usually placed on desk where user can easily select the desired computer to be used. NOTE: The keyboard and mouse inoperative with video monitor displaying Windows 7 startupĤ. Press KVM switch repeatedly until the light emitting diode (LED) is illuminated that identifies the VGA/USB ports connected to the Gateway Windows 7 computer. Power-on the Gateway Windows 7 computer.ģ. To reiterate the only issue with the KVM switch being used was the keyboard and mouse not being recognized by the Gateway Windows 7 computer.ġ. KVM switch connected to both computers.Ģ. The Dell Windows XP always recognizes all 3 shared peripherals (keyboard, video monitor, mouse) when connected via the KVM switch.

The other computer connected to the KVM switch and sharing a keyboard, video monitor, and mouse with the Gateway is a Dell Dimension 8300 running Windows XP Pro (SP3). The Gateway Windows 7 computer always recognizes the video monitor when connected via the KVM switch, it was just the keyboard and mouse that were not recognize and inoperative. Paint attachment (included) shows generic KVM switches purchased that didn't recognize the keyboard or mouse. Subject: KVM Switch Problem Recognition Of Keyboard And MouseĬonfirm that the workaround offered by Bob McDowell (fellow Dallasite) is the solution to the USB wired keyboard and USB wireless mouse not being recognized by the Gateway SX2480 system running Windows 7 Home Premium (SP1) when connected to a 4 port KVM switch. 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. The computers think your devices are always connected too, so there's no re-enumeration / re-detection, every time you switch ports. 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. This one maps your specific keyboard and mouse to each connected system. The other type uses Dynamic Device Mapping, or some similar technology. Sometimes this may work fine for your needs, and it's fast and reliable. Special functions, like volume controls, etc.
That means the OS doesn't know exactly what your devices are, it just considers them to be generic devices. This prevents the OS from having to re-enumerate your devices every time you switch ports, but what it does is it feeds generic keyboard/mouse info to the computers at all times. The downside though is that it can be unstable, requiring Windows to re-recognize/re-enumerate the connected USB devices every time you switch ports.Īnother type of KVM switch uses emulation technology. The USB Hub-type switch has it's benefits, because all devices are seen by the computer exactly as what they are. This is why you hear the sound when switching to or from the computer, signifying the USB reconnecting or disconnecting. The one you have uses a hub-based structure. As far as USB kvm switches go, they are built in a few different ways. 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. Thanks in advance for any thoughts you can give me on this. 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. 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. So i figured I would switch the KVMs on those two stations, but the problem only persisted on the same one, so ruled out KVM issue. Weirdest thing is there is another station with a setup exactly like it, but it does not present that glitch. Have tried upgrading the chipset drivers, enabling and disabling legacy USB support on the BIOS, prevent windows from powering down the USB to save power. 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. The other 3 computers next to it do not have that issue.
This computer will suddenly drop connection to the USB mouse and keyboard, to which is connected via a usb-KVM (Startech SV411KUSB). Hello! I've been dealing with the weirdest glitch ever.
