Displaylink 7.6/Duplex Speed

Hi

We cannot modify the inf file, as it would have to be resigned by Microsoft before we could ship it in our software build and this would change it for everyone.

We have details on how to change this in the registry in the user guide:

http://downloads.displaylink.com/man...rManual7.7.pdf

As you have found, this can be set in the registry. It is possible to find out the subkey using device manager. It is under the Device Key of the USB Ethernet adapter. It shoudl be possible to read this using the WMI interface in a Windows powershell script and use this to change the correct registry value.

An alternative would be to take the Ethernet driver from C:\Program Files\DisplayLink Core Software\CdcNcmDriver, modify the inf and deploy separately. However you would need to uninstall the old Ethernet driver before deploying your new modified one, as I think our driver would be chosen by Windows in preference.
