raspberrypi / usbbootgui Goto Github PK

Here is a summary of how it currently works:

1. A udev rule detects when a RPi is plugged in and launches usbbootgui as root.
2. usbbootgui (or a helper binary) steals the users' X11 key (this will not work under Wayland).
3. usbbootgui runs rpiboot as root with the selected firmware.

Here is how I think it should be implemented:

1. usbbootgui is (optionally) launched when a user logs in to the desktop, with normal user privileges, via the normal desktop autolaunch mechanisms (xdg-autostart).
2. usbbootgui listens on DBus for udev events.
3. A udev rule detects when a RPi is plugged in and gives the current desktop user access permissions.
4. udev sends an event to DBus.
5. usbbootgui receives the event and runs rpiboot as the desktop user.

Additionally, the udev rule should be part of the rpiboot package, so that it can function stand-alone without root privileges.

See commentary on #2 for discussion of why running usbbootgui as root might be insecure if its functionality is extended.

I can implement this if you think it is a good idea.

Hi
Is there an easy way to run this also on Fedora/CentOS/Redhat?

Feature-request

Wouldn't it be awesome if this tool can be enhanced to make a Pi Zero a USB video device class (UVC / webcam) with any Pi Camera but no SD card needed?
