Thanks for contacting us! I am sorry this is not working as expected.
There are some software and power management settings that may be affecting USB devices connected to the docking station. One such setting is part of the Intel Management Engine Interface used in many laptop/notebook computers with Intel processors. The setting attempts to save power by turning off USB devices connected to the system, however it also attempts to turn off devices connected to USB hubs like in the docking station.
Based on your description of the behavior, our first step is to get some additional information from your system to help determine if this could be caused by a power setting like the Intel Management Engine Interface setting mentioned above.
Please let me know the manufacturer name and model number of the computer and I will look up the hardware specifications, alternatively we can gather the necessary information with our PlugDebug log gathering utility.
If you would, please keep the dock connected to the computer with the USB devices connected to the docking station and attach the output of our diagnostic utility PlugDebug ( http://plugable.com/support/plugdebug ) to an email to our support team at ‘firstname.lastname@example.org’ with the subject line ‘Ticket #312207 - Attention Pat’ as this will allow us to examine some log files from your system to help determine the next steps.
