I've installed qubes on a dell desktop that has no PS2 support, and only one USB controller. So it uses a USB keyboard & mouse. During installation I saw no prompt for creating a sys-usb, which I understand is the default when you boot with a USB keyboard.
Here is the output of qvm-pci

I've ready through the USB related documentation, but I'd like to understand my usb options better.
I believe if I try to create a sys-usb for this PC I'll loose my connection to keyboard and mouse in dom0 in that case. Is that correct?
If so, is my only option then to either:
use USB insecurely
don't use USB at all except for the keyboard & mouse attached to dom0
Thanks,
