Im not sure if this fixed my v400 or not but all I did after uninstall reinstall, MPT's and pluging in unpluging, turning off turnning on I just created a profile when iopening MPT's and after that everything works. I connect perfectly in about 10 seconds and I can transfer anything back and forth. The one thing MPT's wont do that P2K does is let you delete any important files. With MPT's I cant even delete the standard ringtones cause it dosnt even show them. I cant see the number or name of people calling on my compute screen. kind of just says "incoming call" over and over.
Still working... Seriously now I pick my profile and it works everytime. Before it was a defult profile and it asked me to set up modem everytime. Now it knows and goes right to the phone aprx 10 seconds.
