I've got a Sony Handycam DCR-DVD101. When I plug connect the USB cable to my laptop (Ubuntu 10) it doesn't mount any storage device.

If I run usb-devices, I see:

T:  Bus=02 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#=  6 Spd=480 MxCh= 0
D:  Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
P:  Vendor=054c ProdID=00c1 Rev=01.00
S:  Manufacturer=SONY
S:  Product=Storage Device
C:  #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr=2mA
I:  If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=05 Prot=50 Driver=usb-storage

The driver says usb-storage, but I'm not sure how to get the device mounted. Is there a way to make this work?

Update: checking dmesg, I see:

Those I/O errors don't look good, is there any hope?

Does the /dev/sr1 device node show up? What happens when you attempt to mount it? –  Eroen Mar 29 '12 at 20:02

Here's my recipe for RHEL/CentOS (Ubuntians beware.)

To show device nodes assigned to USB storage devices

$ dmesg | grep -i "SCSI dev" 
SCSI device sdb: 7716864 512-byte hdwr sectors (3951 MB)

To see the device node for a FAT32 parttition

$ fdisk -l -u /dev/sdb
   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1            8192     7716863     3854336    b  W95 FAT32

To mount the drive

$ mkdir /mnt/flash
$ mount -t vfat -o uid=myname,gid=myname /dev/sdb1 /mnt/flash

Add extra su|sudo to taste.

The problem is shown here:

[259080.002091] sr 5:0:0:0: [sr1] Sense Key : Blank Check [current] 

Several things can cause this.

Most likely, you either have no DVD or a blank DVD in the camcorder at the time you plugged it into your computer. Try inserting a DVD on which some video has been recorded.

It could also be that the camcorder doesn't like the brand of DVDs you've been using, or that the lens is dirty and needs to be cleaned.
