Hello, Everyone
I am running Fedora Core 3, full installation (not an upgrade), all updates
installed. I have been having this annoying problem with my USB2 external
CD-RW drive. The first time it dissappeared, I ended up rebooting and when
the system was done rebooting, I had my CD-RW drive back. This morning, I
checked to see if it was still there (this has happened a couple of times,
with no discernable cause.) It was gone! The last time I used the drive was
last night. I went to bed, slept for a few hours, woke up and checked for
the drive and it was gone. I do not have YUM set up to run automatically, so
there is no possible issue with updates causing this. In fact, this has
happened multiple times over a period of a few weeks, and up until now I
thought that possibly something was causing it to dissappear on it's own.
Now, at the very lease, it sure looks like it (my CD-RW drive) is
dissappearing with no human cause.
Since it just silently dissappears, I have no idea where to start diagnosing
this. Your help is greatly appreciated. Since eliminating Windows from our
home system, I have developed a love for not rebooting, so rebooting to get
my CD-RW drive back is undesired :)
Thanks in advance for your help,

Have you considered running a script every minute via cron to check the
drives status and send the result to a log file? When it disappears,
you'll have a time stamp and then you can check the real logs for what
went on @ that time.
I don't know how you're checking the drives status, but the following
might form the basis for a script:
#!/bin/bash
date >>log.file
# Put your checking code here, and make sure you output to the same log
file, most likely via>>log.file
Then add the script to crontab to run every minute and wait for it to
happen again.
With a bit more sophisticatiuon, you could have the box send you an
email or ring the bell when it occurs.

I just downloaded the FC3 updates-testing kernel. I will proceed to install
that and reboot. I will get back to you with whatever I find.

The time on the above makes me suspicious. 17 seconds after a new hour
(14), this occurs. Could an hourly cron job be causing this? A failure
at 14:00:00, followed by, say 16 seconds of error recovery attempts, and
then when all is lost it produces this message a second later. I know
its a bit far fetched, but coincidence in the computer business isn't
coincidence usually.
Check your previous message logs (message1, message2, etc) to see if you
can find a pattern of failure all around the same time.

Sorry, but you're best able to say if you think its related. You have
the first hand experience.
All we do are Linux servers, and we usually turn USB off via the BIOS,
as we have no use for what we consider a flakey technology. We also
stopped using SCSI when the 3WARE SATA controllers hit the market and
have never looked back. Even backup is done to disk now, so we have
absolutley no use for SCSI.
Now you need some folks that are USB literate, and I'm not.

Hello, Everyone
I am still having the problem that is referred to in the above quoted message,
and in the logs that are quoted in that message. I have two USB2 busses on
our Abit KD7 mainboard. A cable goes from one of them to two ports on the
front of our machine. Another cable goes to two ports on the back of our
machine. Right now, our CD burner (Iomega 52X external, USB2) has
dissappeared (it is connected to a port on the back of our machine. There
only appear to be issues with the ports on the back.) If I rebooted, it
would reappear. If I took the cable from the burner and put it in one of the
open ports on the front of our machine, it would reappear immediately. If I
left it in the front, it would not dissappear anymore. In a minute, I'm
going to try a new experiment: I'm going to unplug the burner and leave it
unplugged for a few minutes, leave the machine alone, and then come back and
plug it in the same port that it dissaapeared from. If that doesn't bring
back the burner, then I will try the same experiemt, but I will replug it in
the other port in the back.
I'm sure someone has already had the thought, "Maybe your burner is bad."
Good question, but I have had our only other USB2 device (EPSON Perfection
2400 Photo) dissappear while connected to one of the back ports. Basically,
I've had it happen that whatever I have connected in the back will dissappear
eventually, but if I plug back in immediately in one of the front ports, it
will come back. Like I said earlier, if I leave any of the "dissappeared"
devices connected to a back port and Reboot, it will reappear. This makes me
at least _Suspect_ that this might not be a pure hardware issue.
Anyway, I will get back to you with the results of my experiment.
Steven P. Ulrick
P.S.: To add insult to injury, I checked the same log files that I quoted from
above. Now they have no reference whatsoever
to /media/cdrecorder, /dev/scd0, hotplug, fstab-sync....
