Hi,
The device enumerates but it is stuck in recovery mode.
Before trying anything can you please follow the instructions in
http://support.displaylink.com/knowl...to-displaylink and send us the debug information?
It would be really useful to us.
Have you already tried installing a different version of the drivers? It's possible that the FW upgrade process would unstuck with an intermediate step. You could install 2.4 for example, connect the device and if everything is fine try 2.5 again.
Please make sure to use the 2.5 final version (2.5 (68993)).
Kind regards,
Carlo
