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

Or you can install another USB card and dedicate it to sys-usb.

Thanks,

Peter
