If you check 'dmesg' output right after you plug it in you should see
something similar to this:
(this is my compact flash reader, but my harddrives behave the same)
usb 2-2: new full speed USB device using address 10
scsi15 : SCSI emulation for USB Mass Storage devices
Vendor: Genesys Model: USB to IDE Card Rev: 0113
Type: Direct-Access ANSI SCSI revision: 02
SCSI device sdj: 1000945 512-byte hdwr sectors (512 MB)
sdj: assuming Write Enabled
sdj: assuming drive cache: write through
/dev/scsi/host15/bus0/target0/lun0: p1
Attached scsi removable disk sdj at scsi15, channel 0, id 0, lun 0
USB Mass Storage device found at 10
it created a device 'sdj' to represent the card, with a single partition.
You need to make sure a handful of modules are installed. modprobe of
usb_storage _should_ have loaded the majority of them. In which case
you should see a whole bunch of neatstuff in dmesg.
You can check and see what modules are loaded by using
lsmod
or
cat /proc/modules
I use a stock 2.6.8-1-k7 image and modules.
I also have udev and hotplug installed to handle the devices.
It can be very complicated unfortunately. So I would suggest starting
to see if you have hotplug installed... maybe that will lead you.
