Or, alternatively, you can just install and use the Maemo Bluetooth Plugin. That will set up your GPS receiver as /dev/rfcomm0. Both these suggestions, of course, don't answer the original question, which is about the sudo changes required to enable bluetooth resetting. Admittedly, setting up rfcomm is better, but for those still curious about how to set up bluetooth resetting, simply gain root access and edit the /etc/sudoers (preferably using the program "visudo") file to add the following line: user ALL = NOPASSWD: /usr/sbin/hciconfig hci0 reset
