I have a usb760 and it works great on my laptop. I went to install it on my son's laptop and it doesn't work. I called Verizon and they sent me the cd to install the VZAccess manager, still did not work. Downloaded it from Verizon's website and still does not work. Here is what happens: it downloads the VZAccess manager and when I insert the Verizon usb760 it says, no device available!! Would someone please help me? My son has down's syndrome and we just bought him a new hp laptop with windows 7 and he wants to use it!! Please try to help me. When I open up network and sharing the Verizon wireless -VZaccess does not even show up.
