thanks, but I don't currently have policykit installed.
I am not even sure I should go through .fdi files to solve this, as it
looks to me that hal is missing a lot of information about my usb stick.
as gustavo said, hal-device (or lshal) shows a list of properties for
every device in the system, and these properties are taken into account
by apps in user space that will have to poke with them.
for what I've understood until now, a usb stick should have properties
in volume.* or storage.* namespace, but in my case this is not true :(
now the question is, what tells hal how to set these properties? it is
udev responsibility? but udev already recognizes the stick, assign it to
a device node, and I can mount it by hand.
I'll try the same stick on my brother's computer running gnome in
ubuntu, just to see the differences in lshal output.
just for completeness, what follows is what is added to lshal output
when I plug in the usb stick; as you can see there is nothing that could
tell e it's time to show a new device.
