D820, docking station, Vista x64, input latency

I'm running a D820 and I just installed Vista 64 Ultimate. I ran the entire install while disconnected from the dock and everything went smooth (SP1 and all patches afterwards). After connecting the laptop to the dock I'm getting a very annoying latency with my mouse and keyboard. The mouse stops responding for as little as half a second, up to 4 or 5 seconds depending on what I'm doing. While typing, the keyboard will also repeat the last key I touched when the issue occurs.

When I connect the keyboard directly to USB port on the laptop the issue goes away. Is this a known problem with the D series dock? Does anyone know if there's a fix for the problem? I didn't have this issue when running Windows XP 32bit ed. Any help would be greatly appreciated.
Thanks.

 

I'm fairly certain it's not a problem with just the dock. I've got a D620 that usually sits on a D-Dock and while it's running XP, I've never had any problems with external devices. If it was working properly before you installed Vista 64 Ultimate, I'd venture this is a software issue, though I'm not sure what you could do about it.

 

Thanks for the tip. I'm going to install the 32 bit version of vista and see what happens.
