Hello,
I'm thinking you could probably use a
Powershell to access Device Manager info.
You can list all DisplayLink hardware with Hardware ID, regardless of the end product manufacturer.
To also remove the Ethernet and audio devices and only get one entry per DisplayLink chip, you can get the "Display name" and match on "Hardware Ids" "USB\VID_17e9&PID_????
&MI_00"
The value in ???? changes based on the device.
If you can't do something like that, you can filter by strings containing "USB\VID_17e9&PID_" and "&MI_00". The
MI filter allows you to only match one interface instead of all interfaces of the composite device.
The Dell D3100 is multi-chip and therefore will have 2 entries.
If you don't care about having repeats, Ethernet and audio, simply look for Hardware Ids including "USB\VID_17e9". This USB Vendor ID belongs to DisplayLink.
The Dell WD15 is not DisplayLink technology, so you'll need anther way to filter it. But the same principle should work, just different Vendor ID.
Kind regards,
Alban
