I've got XP and a brand new RAZR V3re from AT&T, and though MPT 4.51 works well on the phone, I cannot get the p2k drivers to install when I use the UID extraction tool. The phone switches from handset mode and asks me for the drivers "Motorola Accessory", "MCU Data Logger", etc., but will not recognize the .inf files even when pointed to the p2k drivers folder. Is this a registry problem? I suppose what would help is a list of which specific .inf files go with which device, that I might pick them out manually.
Goto developer.motorola.com and sign up for a free account. There yu can download the USB Handset drivers for Motorola phones. Version 2.9 covers the RAZR V3re, and the latest is Ver 3.3.0 Good luck. And a great place to get more info on the V3re is ModMyMoto.com
Current version is 3.4.0 as of 1/31/08 Link is https://developer.motorola.com/docstools/USB_Drivers/Handset_USB_Driver/
