Sony DCR-DVD405 (USB) doesn't get mounted anymore...


Hi! I'm having trouble making my camera get mounted. The strange thing is that a few days ago it DID work... I would connect the camera, select "COMPUTER" in its LCD and then the "A new medium has been detected" would come up to allow me get the camera mounted.

Now this doesn't come up anymore.

The output to 'dmesg | tail' is:

[17183687.264000] usb 5-2: new high speed USB device using ehci_hcd and address 13
[17183687.400000] usb 5-2: configuration #1 chosen from 1 choice
[17183687.400000] scsi11 : SCSI emulation for USB Mass Storage devices
[17183687.400000] usb-storage: device found at 13
[17183687.400000] usb-storage: waiting for device to settle before scanning
[17183692.400000] usb-storage: device scan complete
[17183692.404000] Vendor: SONY Model: DDX-C1002 Rev: R1.0
[17183692.404000] Type: CD-ROM ANSI SCSI revision: 00
[17183692.424000] sr0: scsi3-mmc drive: 32x/32x tray
[17183692.424000] sr 11:0:0:0: Attached scsi CD-ROM sr0
[17183692.424000] sr 11:0:0:0: Attached scsi generic sg2 type 5

And /dev/sr0 exists, but doesn't get mounted. The output to 'lsusb' is:

Bus 005 Device 014: ID 054c:0255 Sony Corp.
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 004: ID 046d:c50d Logitech, Inc.
Bus 001 Device 001: ID 0000:0000

And there it is, in Bus 005.

Any idea of what could be wrong?
Using Kubuntu.
Thanks!

It sounds like your system uses udev & hal to create the device and automount. Try restarting the hal and dbus daemons. That has helped me when a usb pendrive wouldn't automount.

However, your message states that you are trying to mount a camera, but what you posted is from connecting an external dvd drive. Or maybe I am seeing the messages for two devices. Try monitoring the messages when you plug the camera in.
In a shell enter "sudo tail -f /var/log/messages" and then plug in the device.

I just had a problem with an external usb drive. It wouldn't get assigned a device. Looking in /var/log/messages, it indicated that it was being detected but there was a usb problem.

Code:
May 23 08:25:42 hpamd64 kernel: usb 3-1: new high speed USB device using ehci_hcd and address 11
May 23 08:25:42 hpamd64 kernel: hub 3-0:1.0: Cannot enable port 1.  Maybe the USB cable is bad?
May 23 08:25:42 hpamd64 kernel: usb 3-1: new high speed USB device using ehci_hcd and address 12
May 23 08:25:43 hpamd64 kernel: hub 3-0:1.0: Cannot enable port 1.  Maybe the USB cable is bad?
May 23 08:25:43 hpamd64 kernel: usb 3-1: new high speed USB device using ehci_hcd and address 13
May 23 08:25:44 hpamd64 sudo: jschiwal : TTY=pts/1 ; PWD=/home/jschiwal ; USER=root ; COMMAND=/usr/bin/tail /var/log/messages
May 23 08:25:44 hpamd64 kernel: usb 3-1: device not accepting address 13, error -71
May 23 08:25:44 hpamd64 kernel: usb 3-1: new high speed USB device using ehci_hcd and address 14
May 23 08:25:44 hpamd64 kernel: usb 3-1: device not accepting address 14, error -71
Restarting the dbus and hal daemons didn't help. Next I tried: "sudo /sbin/modprobe -r ehci_hcd" and then "sudo /sbin/modprobe ehci_hcd" to unload and reload the ehci_hcd kernel module. This worked.

Thanks for all this. I'm going to try it.
But (just for my curiosity...) rebooting my system, as I already did (old W days...), shouldn't do the job of reloading the modules and restarting the services? Any way I'm trying this.
And that's the set of messages that come up when I plug the camera, I'm sure. I've been reading some other posts before I read this, and made sure to run dmesg before, then plugging, and then running it again. I checked the numbers also, so I'ts the same as monitoring realtime.
It is a mini DVD camera, and that may be why it detects it like a an external DVD drive.

Unloading and reloading the modules didn't work...
The 'sudo tail -f /var/log/messages', both before and after unloading/reloading, reported this when connected:


Code:
May 23 12:04:32 fcksys kernel: [17184883.036000] usb 5-2: new high speed USB device using ehci_hcd and address 4
May 23 12:04:32 fcksys kernel: [17184883.172000] usb 5-2: configuration #1 chosen from 1 choice
May 23 12:04:32 fcksys kernel: [17184883.172000] scsi3 : SCSI emulation for USB Mass Storage devices

May 23 12:04:37 fcksys kernel: [17184888.176000]   Type:   CD-ROM                             ANSI SCSI revision: 00
May 23 12:04:37 fcksys kernel: [17184888.200000] sr0: scsi3-mmc drive: 32x/32x tray
May 23 12:04:37 fcksys kernel: [17184888.200000] sr 3:0:0:0: Attached scsi generic sg2 type 5

...and this when disconnected:


Code:
May 23 12:09:05 fcksys kernel: [17185156.716000] usb 5-2: USB disconnect, address 4

Yesterday there was some usb-storage messages... I remember doing some kind of modprobe or something to usb-storage too. But now they don't show up... could this add something up?
