HOWTO: Fix MTP USB driver problem in Windows 7

Published on 2012/03/23 by Igor Levicki

Few days ago I was installing Motorola Milestone 2 mobile phone drivers and there was an MTP USB Device that kept refusing to install properly.

After a quick Google search I found a "solution" — select MTP USB device in Device Manager, select Update driver, then manually select USB Mass Storage. Without those steps PC refused to mount the phone storage even though it was in USB Storage Mode.

Unfortunately, that doesn't fix the problem permanently because as soon as you unplug/replug the phone it will again try to install the MTP USB Device and it will, of course, fail miserably.

I traced it down to a file C:\WINDOWS\INF\wpdmtp.inf. After removing it, Windows no longer tries to install MTP USB device but installs regular mass storage. Keep in mind that this is a dangerous workaround so be sure to backup the file if you decide to try it.
