I have an HP Omnibook 6000. I just got MS streets and trips 2008 with the gps receiver. I installed the software on my laptop, plugged the usb gps receiver in, and ms streets and trips cant find it. I have unplugged it several times with the same results. I tried putting it in different ports on my hub. No luck. Then I installed the software on my desktop, and it works fine. Any ideas?
