[gentoo-user] "hotplugging" usb devices no longer working

[Allan Gottlieb]

I have a sansa MP3 player and a Flip Video.  Each plugs in as a usb
device and presents as a fat file system.

Both used to work, but don't today (it is has been a while--few
months--since I last plugged them in.

Now the device screen shows that it is connected, but I see nothing on
the computer
  df shows no new file system
  mount shows no new file system

I checked and FAT/VFAT are in the kernel

# DOS/FAT/NT Filesystems
CONFIG_FAT_FS=y
CONFIG_VFAT_FS=y
CONFIG_FAT_DEFAULT_CODEPAGE=437
CONFIG_FAT_DEFAULT_IOCHARSET="iso8859-1"

Both hal and udev are running

Any help would be appreciated

What "device screen" do you mean?  And where are you looking "on the
computer"?  When I insert a usb stick, there's a lot of output in
/var/log/messages about the stick and the partition on it.  Then I use
"mount /media/usbstick" to mount it according to the appropriate entry
in my /etc/fstab.  Speaking of which, what's your /etc/fstab look like? 
If you use "tail -f /var/log/messages" and then plug the device in, does
it see that it's connected?

I suspect you're talking about auto mounting, such as KDE or Gnome does;
can you manually mount them?  If not, then I doubt auto mounting will
either.

This is a test.  Please ignore (see prev msg for explanation).

Had this problem too. Not sure if this suits your case. Have you tried
using UUID in place of /dev/sdx? Use blkid to get the UUID for the
device and replace /dev/sdx in fstab.

Do the devices show up in dmesg like this?
