I did the following for accessing my jtag device.
Created /usr/share/hal/fdi/information/20thirdparty/10-olimex-programmer.fdi containing :-
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<!-- Grant access to program the Olimex devices to uucp group. -->
<!-- <match key="info.subsystem" contains="usb_device"> -->
<match key="usb_device.vendor_id" int="0x15ba">
<append key="info.capabilities"
type="strlist">olimex-device</append>
<append key="info.capabilities"
type="strlist">access_control</append>
<merge key="access_control.file"
type="copy_property">linux.device_file</merge>
<merge key="access_control.type"
type="string">olimex-device</merge>
<merge key="access_control.grant_group"
type="strlist">uucp</merge>
</match>
<!-- </match> -->
</device>
</deviceinfo>
I then added myself to the uucp group and rebooted, for some reason
restarting haldaemon did not work correctly. Now openocd works without
having to be root. Hope this helps.
I do wish this udev/hal/policykit magic was better documented.
