Thank you so much for reaching out to us, as well as providing this great information. I am sorry that you are experiencing this problem, but I would be happy to assist!
Based on the fact that this setup used to work correctly, and perform the behavior you originally wanted, we may be dealing with a Windows or software related issue. The sleep and wake functions related to the docking station and hub are all configured and setup by the system and operating system, and the docking station should not effect any of this behavior.
Just to make sure I have all of the right information, could you please visit www.plugable.com/support/plugdebug and download and run our PlugDebug application. This will then create some log files in a .zip folder on your desktop. Once the .zip file is located, could you please attach it to a direct email and send it to firstname.lastname@example.org with “Ticket No 189194” in the subject line?
Thank you for your patience,
Product Owner & Technical Support
