How to remove all sys-usb restrictions?

I’m still troubleshooting sys-usb peripherals issues. At this point I just want to see if I can get the peripherals to work running inputs thru sys-usb without any security restrictions at all.

I just want to remove them all, and then work backwards, until I find what is causing the problem.

I’m looking at the settings in /etc/qubes-rpc/policy. I’ve removed all the restrictions in qubes.InputTablet, qubes.InputMouse, qubes.InputKeyboard qubes.USB.

Is there any other place I can adjust params regulating inputs from USB->sys-usb->dom0?

/etc/qubes/policy.d among others. I’m not sure what you mean when you say restrictions.
