Details emerge about mysterious Windows WPD driver

March 9, 2017 brianradio2016

Overnight sleuthing by German Windows guru Günter Born has shed light on the mysterious driver I talked about yesterday. We now know that the driver that appeared on many Windows 7, 8.1, and 10 systems wreaks havoc on USB connections for some smartphones, including Android and Lumia phones.

Born writes in his blog that found the patch in the Windows Update Catalog—not an easy task given the catalog’s anemic search capabilities — and dug into the update file. The “Microsoft – WPD – 2/22/2016 12:00:00 AM – 5.2.5326.4762” patch contains drivers for MediaTek Android devices. MediaTek, based in Taiwan, provides chips for a huge variety of phones. This “new” driver is from Shenzhen Diadem Technology Co.

Specifically, Born says:

The .inf files shipped within the CAB file specifies that this update supports the following drivers:

  • Android ADB Interface
  • Android Composite ADB Interface
  • Android Bootloader Interface
  • Android USB Driver

Other .inf files contain information about MTP protocol support via WPT driver.

What to make of the alphabet soup? In a nutshell, Windows Portable Devices (WPD) drivers allow Windows “to communicate with music players, storage devices, mobile phones, and many other types of connected devices.” WPD is a smorgasbord, containing many different drivers of different types.
