I see others have this problem too. Everything new and updated plus I spent over an hour on the phone with Verizon tech.
USB modem installs fine and shows as working in device manager but Access Manager can't find it. When AM looks for the modem it sometimes says "detecting modem" and other times says "configuring modem" but it never does either and ends with the same error "device not detected".
I disabled the wireless card, shut off the firewall etc but still no luck.
Any solutions yet??
