you've not restarted harddrake, have you ?
if yes, this bug can be closed: harddrake2 do hardware detection only at startup
(else, exploring the devices tree wouls be quite a lot slower and unusable)

description:
I have a CD-RW which I sometimes access using a IDE->USB2.0 case enclosure.
When I connected it, it was recognized and a /dev/ entry was created.
When I disconnected it, the /dev/ entry remained and harddrake2 still displayed
the outdated drive information.
What I expected: The /dev entries to be removed when I disconnected the device.
This is on a fresh cooker install from yesterday. Kernel is 2.4.21.0.pre4.1
Given below: The appropriate lines from the kernel log, /proc/bus/usb/devices,
lspvi -v, the /dev listing and the harddrake2 output.

The results from cat /proc/bus/usb/devices with the CD drive connected show
that it is indeed registered:

Here's the state of the /dev entries after I have disconnected the device:
[root@localhost root]# ls -l /dev/scd0
lr-xr-xr-x 1 root root 31 Feb 1 10:37 /dev/scd0 ->

Harddrake2 still shows the old information after the device has been
disconnected. It lists scd0 as a drive and gives the following
information about it:
Bus: SCSI
Location on the bus: 0:0
Channel: 00
New devfs device: scsi/host1/bus0/target0/lun0/cd
Old device file: /dev/scd0
Floppy format: HP CD-Writer+ 9100
Media class: cdrom

If we look at /proc/bus/usb/devices, we see that the device has indeed
disappeared from the bus:
