This bug still remains.
Tonight, I plugged a usb card reader in and a /dev/sda entry was created.
After I had unplugged the device, I looked at the logs and saw a message stating
that the device had been unplugged.
However, the /dev/sda entry still remained.
I then tried to run diskdrake, and it obviously believed that the device
formerly connected to /dev/sda still was connected as it asked me:
"I can't read the partition table of device sda, it's too corrupted for me :(
I can try to go on, erasing over bad partitions (ALL DATA will be lost!).
The other solution is to not allow DrakX to modify the partition table.
(the error is unknown partition table format on disk /dev/sda.)
Do you agree to loose all the partitions? [Y/N]"
Thierry, if you don't think this is a mistake in devfsd, where do you think it
is? In the kernel? In hotplug? Work with me, I gave all the information I could
think of in the original bug report: lspci, logs, /proc/bus/usb/devices and a
listing of relevant entries in /dev. What more can I do in order to facilitate
this problem being solved?

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the outdated drive information.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:
