Vista - IPAQ Mobile Device Driver Fails To Install

My IPAQ hx2495 works fine when used with my old XP laptop. My new HP laptop
that came preloaded with Vista Home Premium fails to install the windows
mobile device drivers for the IPAQ. WMP can see the IPAQ and I can access
the files on both the device and the storage card. Looking at the error on
the driver install for the mobile device all it says is unable to open
device. I have installed the latest WMDC and any other Vista updates. I
have the current firmware installed on my IPAQ as well. Is anyone else out
there having this same issue? Is this something Microsoft is working on? HP
says it is a Microsoft issue and Microsoft says it is an HP issue due to the
OEM OS. Can someone help me , please??
