This Plugin to scan for usb devices. You should activate this
plugin if you use mainmenu plugins for special usb devices
like camera.py.
You can also set USB_HOTPLUG in your local_config.py to call
an external program when a device is added. USB_HOTPLUG is a
list with actions. Each action is also a list of device, message
and program to call. Limitation: this works only when Freevo shows
the menu and is not running a video.
Example:
call pilot-xfer when a pda with the id 082d:0100 is pluged in:
| USB_HOTPLUG = [ ('082d:0100', 'Synchronizing',
| '/usr/bin/pilot-xfer -t -u /local/visor/current') ]
