Well, what version of MPT works with v551 phones? I have been trying for 2 days now, and this is really getting annoying, I am getting tempted to just buy the fusking program and cable at the phone store.
LOL Version 3 should work fine. Go here to download the Motorola USB driver though. http://www.cellphonemall.net/wireless/store/c_data_cables.asp Hope this helps. Don't waste your money. This may not even work for you. I'm guessing you already have the program since you didn't indicate otherwise. If not, search the forum a little more. There are copious threads with new information including posts I've made recently with Installation guides from Motorola.
