On Ubuntu Jaunty (x86_64), I have difficulties with file permissions of my Garmin GPSmap device. A number of older postings recommend vaguely that HAL + policykit should be used to set the respective file permissions. lshal for the GPS device yields udi = '/org/freedesktop/Hal/devices/usb_device_91e_3_noserial' info.linux.driver = 'usb' (string) info.parent = '/org/freedesktop/Hal/devices/usb_device_1d6b_1_0000_00_1d_2' (string) info.product = 'GPSmap (various models)' (string) info.subsystem = 'usb_device' (string) info.udi = '/org/freedesktop/Hal/devices/usb_device_91e_3_noserial' (string) info.vendor = 'Garmin International' (string) linux.device_file = '/dev/bus/usb/004/010' (string) linux.hotplug_type = 2 (0x2) (int) linux.subsystem = 'usb' (string) linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1d.2/usb4/4-1' (string) usb_device.bus_number = 4 (0x4) (int) usb_device.can_wake_up = false (bool) usb_device.configuration_value = 1 (0x1) (int) usb_device.device_class = 255 (0xff) (int) usb_device.device_protocol = 255 (0xff) (int) usb_device.device_revision_bcd = 1 (0x1) (int) usb_device.device_subclass = 255 (0xff) (int) usb_device.is_self_powered = false (bool) usb_device.linux.device_number = 10 (0xa) (int) usb_device.linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1d.2/usb4/4-1' (string) usb_device.max_power = 300 (0x12c) (int) usb_device.num_configurations = 1 (0x1) (int) usb_device.num_interfaces = 1 (0x1) (int) usb_device.num_ports = 0 (0x0) (int) usb_device.product = 'GPSmap (various models)' (string) usb_device.product_id = 3 (0x3) (int) usb_device.speed = 12.0 (12) (double) usb_device.vendor = 'Garmin International' (string) usb_device.vendor_id = 2334 (0x91e) (int) usb_device.version = 1.1 (1.1) (double) Based on informations I gathered from googling around I created the following fdi files: /etc/hal/fdi/information/10-gps-devices.fdi : gps garmin linux.device_file /etc/hal/fdi/policy/10-gps-devices.fdi access_control gps gps.garmin.interface gps Afterwards, I used polkit-gnome-authorization to grant access to "Garmin GPS" to my user id. However, the device is still not accessible: $ gpsbabel -t -w -i garmin -f usb: -o gpx -F test.gpx Claim interfaced failed: could not claim interface 0: Operation not permitted $ getfacl /dev/bus/usb/004/010 getfacl: Removing leading '/' from absolute path names # file: dev/bus/usb/004/010 # owner: root # group: root user::rw- group::rw- other::r-- Do you have any suggestions how to fix this? Thanks! Ulf
