Running Aksy Programs as normal user

A common reason for not being able to set up a USB connection is that the device permissions are set too restrictive (read-only, root permissions). This short HOWTO describes how to configure [HAL http://www.freedesktop.org/wiki/Software/hal] on Ubuntu to change the permissions each time a device is connected.

Ubuntu

Ubuntu mounts usb devices under /dev/bus/usb, so one should check /dev/bus/usb/<bus id>/<device id> to verify. The output from lsusb can be used to determine bus and device id. Highly likely the bus and device ids will change when the sampler is reconnected; HAL can be used to automate the chown on connect. See the config directory in the src distribution (or the latest version online) for an example policy file (copy to /etc/hal/fdi/policy if you're using Ubuntu) and permissions script. The set-permissions script needs to edited to contain your own user id and installed in /usr/bin/set-permissions.

Other distributions

OpenSuSE users should copy the .fdi file in /usr/share/hal/fdi/policy/
