Hi All

I am not sure if this is the right forum to ask...  but it seems like
the right first step.

I am running Debian 4.0 with custom built 2.6.20.6 kernel.

I have a USB media reader, vendor ID: 0x058f, Prduct ID:
0x6362, whic is a CF/MMC/SD/SM) etc reader that normally shows up as a
SCSI device.

I am seeing some behavior that puzzles me:

when I attached this device via USB to a newly booted  system it's
detected and all is well, so long as the media card is in the reader
at the time. As expected the usb-storage module and sd-mod load,
devices are scanned, partitions are found and so on.

If I attached it without any media cards in it, or I have unmounted
and removed a media cerd from the reader, it shows up as a bunch of
SCSI removable devices  (sda, sdb, sdc, sdd) , but inserting a card
into the reader does not result in a mountable SCSI device, even if I
know which of them i need to mount. It seems that after first insert,
there is no rescanning of the devices.

So my question is:

is there a way, using hotplug or udev or otherwise to:

a) scan the USB card reader and detect media insertion
b) scan the media and detect partitoons, etc
c) NOT runa  daemon tnat auto-mounts them for me - I do not want to
auto mount the devices, i just want to know when they are inserted...

Tomasz
