Ok so I had no problem when I installed my USB modem on my laptop. Then the motherboard went on my HP, but I'm not here to complain about HP. So I changed to my wife's Compact (yeah not much better). However, all the sudden my USB modem wasn't being detected by VZaccess manager. WHAT THE CRAP! Search all the forums. Nothing. Called tech support. No help. Then the next day in the shower (where I seem to remember everything). I remembered they guy from Verizon telling me that the USB modem worked like a dial up connection. Then I remembered when optimizing my wife's crappy computer I turned off the telephony service (like that saved me tons of computing power). When I turned it back on..OOOOSNAP! Recognize my USB right off the bat. I just wish Verizon could have told me that before I wasted 3 hours of my life on the phone. I see a lot of people resorting to a complete reinstall to fix this same issue. The funny thing is in all version of MW the telephony is manual or automatic. Depending on what service pack you have. HOPE THIS HELPS SOME POOR SOLE
