Passthrough for USB keyboards isn't enabled by default

[ghost]

Qubes OS version (e.g., R3.1):

R3.2

Affected TemplateVMs (e.g., fedora-23, if applicable):

N/A

---

Expected behavior:

When connecting a USB keyboard for the first time it should ask if you want to allow the keyboard to passthrough to the rest of the system.

Actual behavior:

Nothing happens.

Steps to reproduce the behavior:

1. Connect your USB keyboard.

General notes:

The solution to the problem is to add sys-usb dom0 ask on the top of the file /etc/qubes-rpc/policy/qubes.InputKeyboard. Passthrough for USB mouses is already enabled using this method.

This is design decision. Having control over the keyboard gives in practice control over the whole system, so it should be really consistent decision to allow sys-usb to control keyboard. Just one-click confirmation is too little barrier. More details: https://www.qubes-os.org/doc/usb/#tocAnchor-1-1-4
