Keyboard & mouse not recongnized on KVM switch  

On my new Acer M7720 (X58 Core-i7-920) I have Vista HP 64 bits working fine with an Conceptronic 2 port KVM switch so I can also use keyboard, mouse & monitor on my old PC. On the new Acer I also installed Windows 7, but here the mous and keyboard are not recogized when connected through the KVM switch. I have to stick both in the front site USB ports, then baoth are working. When I stick them in the KVM switch, you can here the USB connect sound and both devices are shown under unknown devices, wereas the are shown under devices when connected through the front side USB ports.

Any one an idea how to salve this? by the way the KVM switch is also 'seen' by W7 under devices even though it doens't need any drivers. All conncected devices are shown (I have also 2 USB drives)

I had the same problem w/ windows 7 build 7022 x86 and kvm cs-62du. I figured out that you have to put your laptop to sleep mode and switch to that port on kvm before connection. After wakeup external monitor gets recognised on correct resoultion. To get usb mouse/keyb worked you might use other (black, not violet) usb socket. This is a workaround, not a solution, I know.



My dell d630 generates bsod after docking 50-50 percent If I not use sleep-wakeup trick before docking.

Windows 7 device management requires full USB device description passed to all connected systems of KVM switch. Your KVM switch did not support that function.
Find KVM switch support DDM or true USB simlulation.

I purchased this device. It works fine with my Windows 7 x64 desktop and Vista x32 connected devices.

ConnectPRO, Finest Quality KVM Switches

Where did you find the ConnectPRO UR 12+, I can only find the
UR12, which does not support DDM. I could not find any other KVM
switches that support DDM.

Thanks,
Jim

I bought the 14+
