#USB-checking

##USB folder ###USB_devices folder Check if a connected devices was already seen by the computer. If the device was not seen, it will ask for your permission to add it to a trusted file (known_host in our case) - for the command line interface or you could add them manually from the Gtk+ interface.

###For the command line

python usb_checking.py

###For the Gtk+ interface

python usb_listing.py

###Updates

• Add pyudev library to check for new added devices (no more expensive loop)
• Add pyusb library to get the device descriptors, custom search and device binding
• Made a gnome-shell-extension to block new USB connected devices when the screen is locked or when the user wants

USB_DBus folder

USB inhibit

This script could run in 3 modes (the complete description could be find in the script):

1. continuous mode --> block all the new connected devices until you decide to kill the process: python usb_inhibit.py

2. a command mode --> block all the new connected devices until a command is finished: python usb_inhibit.py -- sleep 10m

3. allow mode --> allow a specific class of devices: python usb_inhibit.py -- allow 0x08 0x01 This would allow only Audio and USB Mass Storage devices.

USB_DBus folder

USB turn on

python usb_on.py bus_id (bus_id the given parameter)

USB turn off

python usb_off.py bus_id (bus_id the given parameter)

USB DBus

For this part is used a listener (to check when the screensaver is activated) and a dbus system service to start/stop the blocking.

Also the dbus service is used in the gnome-shell-extension and more updates for the extension are yet to come.

Still working on improvements regarding the interface.
