Public bug reported:
Binary package hint: hal
Ubuntu 6.06 i386 system.
hal package version: 0.5.7-1ubuntu18
Hotplugging a USB flashdrive succeeds only for the first time (because my system
uses only ide drives and so "sd_mod" is not loaded automatically at startup).
At plug time sd_mod is loaded automatically and the device is correctly mounted
and correctly listed in the hal device manager.
Then disconnecting and plugging the same device a second time makes the hal
device manager display only a "SCSI device" without any volumes.
The device node "/dev/sda1" is correctly created and the flashdrive can still be
mounted manually (with "mount" or "pmount").
This does not happen with all USB storage devices (with 3 flash drive I tried,
only one showed this problem, all 3 flashdrives works correctly in MacOSX and
WinXP).
I tried this:
1)disconnect the USB flashdrive
2)manually remove the "sg" kernel module (rmmod sg)
3)manually remove the "sd_mod" kernel module (rmmod sd_mod)
4)reconnect the USB flashdrive
and the device is detected properly.
Another note:
Killing the hal daemon and restarting it (without disconnecting the device) gets
the USB flashdrive automounted on the desktop (however I didn't investigate on
this option too much).
Thanks in advance to anyone who will read this.
Bye
Marco
