Subject: Re: How  to manage multiple USB controllers

> I don't think you really have 6 controllers do you?
dom0$ lspci | grep USB
returns 6 PCI devices:

00:12.0 ... SB7x0/SB8x0/SB9x0 USB OHCI0 Controller

00:12.1 ... SB7x0             USB OHCI1 Controller

00:12.2 ... SB7x0/SB8x0/SB9x0 USB EHCI  Controller
00:13.0 ... SB7x0/SB8x0/SB9x0 USB OHCI0 Controller
00:13.1 ... SB7x0                         USB OHCI1 Controller

00:13.2 ... SB7x0/SB8x0/SB9x0 USB EHCI   Controller

Is it 6 controllers?

Thanks for sharing your USB topology and controller assignment.   Have you been 
able to hide the USB controllers from dom0 as described in 
https://www.qubes-os.org/doc/usb/#creating-and-using-a-usb-qube?  So that lspci 
returns an epmty string.

How did you determine that the 2 EHCI(s) are routed through XHCI?  What does 

dom0$ lspci | grep USB
return?  Does it show 3 controllers or one?

In the later case, XHCI is attached to sys-usb, and 
 is employed to pass it to dom0. Is my understanding correct?   Are you able to 
log in (after the boot) using the USB keyboard?
