Linux GUI Client not seeing USB Hub

I have a Server running on Windows 10 and a GUI Client running on Ubuntu 18.04 Linux machine.
On the Windows 10 machine i have 2 port USB Hub device to which 2 child USB devices are plugged in.
On the Linux Client i can see the 2 child USB devices but not the USB Hub. I need to be able to see the hub as well for my Linux application to work

No virtualhere doesnt pass through hubs, they are transparent, only the attached devices are passed through

#3

Any chance you could make some changes to the code to pass through the hubs?

#4

No sorry
