Can't access the internet

It seems the information about your USB controllers is only in the .yml file, not on the screen.

sys-whonix VM provides Tor connection, so it should not be relevant here.

These seem very relevant. I tried to search for such error on this forum and found this and this. Those threads have some solutions, which hopefully can help you.

I guess this short intro might help you to understand the general idea of Qubes OS.
