However, for the drives that don't work, it doesn't do that. I haven't
found out yet what kind of GDriveIface G_DRIVE_GET_IFACE (drive)
fetches in g_drive_get_volumes(). One thing is certain:
iface->has_volumes() is 0, there!
After re-installing the system from scratch (total bummer) and some more
debugging, I discovered the gvfs-gdu-volume-monitor executable. I still
don't grasp how g_drive_get_volumes() gets invoked, though.
I also found out that in gio's g_drive_get_volumes() function, the iface
pointers are the same for all USB sticks. Unfortunately, gdb doesn't
want to step into (*iface->get_volumes)(drive) for reasons obscure to
me, so I have no idea what's being called. Anyway, it ought to be better
to find and debug the code that sets up the GDrive objects, I suppose.
Where is that?
Even though Debian is using the GDU code, I ran udisks --dump and attach
the output to this email, just in case there is something in it which
might ring a bell. For me, the diff looks innocent. (udisks-ok.log is
with an USB stick that does work, udisks-bad.log with one that does not.)
-richy.
