I have a Pegasus R6 that works with my Macbook but won't connect to my new Alienware 15 R4 laptop.  I installed the windows driver from and the Promise Utility from  I'm running Windows 10 Pro v1803.  I have an Apple Thunderbolt 2to3 adaptor.  When I plug in the device the Thunderbolt Software pops up and asks if I want to connect.  I select 'Connect Always' but then nothing happens.  I can see the device in the list of attached devices but the connection status is 'Not connected'. 

What can I do?

Were you able to solve it?

I have the exact same problem.

I have the same problem as well. Would really like to continue to use this device.  I am not using an Apple Thunderbold adaptor however, but a 3rd party one.  Promise utility says "Device can not be found" which makes sense beecause the thunderbolt driver sees it, but is not connecting.
