DisplayLink support for Windows PE

DisplayLink software is not supported and cannot be installed on Windows PE. However it is possible to install the Ethernet driver under Windows PE. The Ethernet driver can be found in:

C:\Program Files\DisplayLink Core Software

 If using V7.1 or older software/firmware on the device, then the Ethernet driver from this directory will be required:

C:\Program Files\DisplayLink Core Software\CdcEcmDriver

 For V7.2 or later, the Ethernet driver from this directory will be required:

C:\Program Files\DisplayLink Core Software\CdcNcmDriver

 This driver can be installed under Windows PE with the command:

 drvload dlcdcecm.inf

Installing both Ethernet driver versions


It is possible to identify the Ethernet driver required by the device by looking at the SubClass ID of the Ethernet adapter in device manager:



 If the device requires the ECM driver, this will be shown as USB\Class_02&SubClass_06. If the device requires the NCM driver, this will be shown as USB\Class_02&SubClass_0d. It should be possible to create a script to load the appropriate driver based on the SubClass ID.
