Dell d/port advanced port replicator and IoGear DVI kvm - keyboard problems

Question

I just purchased a xps m1710 laptop and the Dell d/port advanced port replicator to use as a docking station.  I have the docking station hooked up to my IoGear DVI KVM switch.  My monitor and usb Wacom tablet work fine but the docking station is not seeing the keyboard.  If I plug the KVM's usb directly into the laptops usb port then the keyboard works, but that somewhat defeats the purpose of having a docking station.  Does anyone know of a solution to this problem or if the Dell port replicator and IoGear KVM are incompatible.   Thanks for help

Update - problem solved!  Here's how I fixed it for others that may have the same problem.   Hook a USB hub to the Dell d/port, then plug the IOgear KVM USB into the hub.  That's it!  I used the Micro Innovations 4-port USB hub (only $16) and it works great.

I am experiecing the same problem with my D620 and the DPort. I also have the IOGEAR DVI KVM. Its funny, because i have the RGB version of the KVM at my cubicle and the problem doesnt exist.   I would try downgrading the BIOS from A07 to something lower like A06 or A05. I will try that and let you know the outcome.   I am unsure of what BIOS features I lose by downgrading though.

Man I've been messing around with this for a couple of years enabling and disabling my USB controller to get it to work (previously with a D600).  I forgot my flat screen has a built in USB hub in it.  It now works like a charm.  Thanks.
