I have to chime in on the USB760 issues...
1) ALWAYS SAY NO TO ANY SERVICE OR MANAGER UPDATES!! each time (three) I attempted to download the updates, my verizon manager stopped recognizing the device, and my laptop didn't see it either!
The only way I found to correct this is to uninstall EVERY aspect of the manager software, including anything that says "broadband driver updates" or Novatel upgrades....if any part is still in your system, your computer won't reload the program from your usb device....it won't even see the device! In fact, even searching your system information won't bring up the USB760.
2) Novatel and Windows suddenly don't get along and it causes MULTIPLE error messages on re-install! Once I have uninstalled everything, when I plug in my USB device, the laptop starts piling up messages about Novatel software not being in some windows programming protocol and do I want to continue anyways. My system also starts recognizing "new" individual drivers and devices. There's about 27 messages to get through before the install completes....this did not happen when I first used this device. The whole thing makes me very nervous about what exactly I am loading off this device and what is it doing to my laptop?
3) Connection seems spotty....it appears that whenever the light on the device is blinking, my speed goes right out the window. I thought that once you plugged the device in, you were on...no ins and outs? My phone always has full bars here, so not sure what the connectivity range is for the usb device?
The only way I could get back to normal, though slow, operation was to never attempt any upgrades again.
Thanks....vent over...hope to hear from anyone about possible solutions : )
