Oh, Christophe! There is no "eject" item in context menu for flash and ordinar drives! Have you one? If it was so simple, I will not ask a question, I'm not so stupid. Context menu have only mount and unmount items. Only cd/dvd have eject. And yes, filesystem is sync before unmount - LED blinks. Whats wrong?
please explain what else you expect. Eject litterally means take off the device, after umounting it. For a CDROM it should open the tray. For a USB Flash you have to take it off manually but I still do not see the difference.
But, line 136 says that suspend is no longer supported. In fact, the .../power/level file does not exist on my 2.6.34 kernel. Perhaps a patch could be made to put the old code back in... => http://www.mjmwired.net/kernel/Documentation/usb/power-management.txt#136 This may or may not be why it isn't there.
I wonder if PCManFM can be extended with extra menu items, like Nautilius...? That way the eject command could be issued quite easily.
Just a couple of thoughts, hope it helps & sorry if it's totally useless!
