Previous Configuration:An Aukey USB 3.0 powered hub is connected on the USB 3.0 host port of Q10 Pro. Attached is my DAC, 2TB portable drive, and USB 3.0 connection from my Dell monitor. My mouse and keyboard on the two USB 2.0 ports. All working fine since May when unit is purchased.
Problem:My DAC wouldn't play. The app sees the DAC but would not play. No lights on my powered hub to indicate connection. However my 2TB portable drive and USB of my Dell monitor functions properly.
Experimentation:Tested my DAC from my Android phone via OTG and it works as intended.
Tried to move the mouse on the Aukey powered hub and it won't work.
Tried to move the keyboard to the hub and it won't work as well.
Removed the the powered hub from the USB 3.0 port of my Q10 Pro and plug directly the DAC and later the keyboard and it won't work.
And my 2tb portable drive and USB 3.0 from my Dell montior all working fine.
Current configuration:Using currently the USB 3.0 hub from my Dell monitor w/c is plugged on the USB 3.0 port of my Q10 Pro.
Attached to it are my mouse, keyboard and the Aukey powered hub.
My DAC is connected directly to one of the USB 2.0 ports.
Thoughts on why?
