I have no problem with my USB key devices: there are mounted automatically.
But for the LeapFrog Tag USB device it is not mounted automatically.

enter image description here

So I look in the Ubuntu documentation to mount USB manually.

But fdisk returns only info about my hard disk, nothing about LeapFrog USB.

$ sudo fdisk -l
Périphérique Amorce  Début        Fin      Blocs     Id  Système<br>
/dev/sda1   *        2048   606713855   303355904   83  Linux<br>
/dev/sda2       606715902   625141759     9212929    5  Étendue<br>
/dev/sda5       606715904   625141759     9212928   82  partition d'échange Linux / Solaris

I found some commands able to list this USB device:
- lsusb
- udevadm (need unplug the device before using the command and then plug it to see it)

$ lsusb
...
Bus 005 Device 002: ID 0f63:0700 **LeapFrog** Enterprises POGO<br>

and 

$ udevadm monitor --udev
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
UDEV  [1915.787445] add      /devices/pci0000:00/0000:00:1d.3/usb5/5-2 (usb)
UDEV  [1915.796226] add      /devices/pci0000:00/0000:00:1d.3/usb5/5-2/5-2:1.0 (usb)

So I hope to be able to mount it with something like:
sudo mount -t ??? /dev/sdb??? /media/leapfrog

How can I know which option and what is the path of the device?
Is there a way to use USB ID from lsusb ?

  • Is your device the same as what is described in this wiki page? maybe the unlocking stuff there could help? http://elinux.org/Didj_USB_Mounting – fossfreedom Jan 15 '12 at 10:03
  • I would say no, but after search on google, my Tag and this Didj seems to be products from LeapFrog company. So I'll see if unlocking can help - thank you – Boris Jan 15 '12 at 10:11

The easiest way 

sudo -i
blkid

then plugin ur usb then run

blkid

before Usb

enter image description here

After Usb Plugged-in

enter image description here

so now i know my usb is vfat & its sdb1

if its auto mounted and u want to mount it manually 1st run umount /dev/sdb1

now manually mounting 

mkdir /media/myusb

or make a folder where u want to mount your usb

mount -t vfat /dev/sdb1 /media/myusb

now usb has been mounted on /media/myusb

  • unfortunately command blkid does not list anything new, only command lsusb does, so I can not still get any /dev/s??? – Boris Jan 28 '12 at 14:03
  • have you checked the 2 linked at the end – One Zero Jan 28 '12 at 14:08
  • what I understand from your 2 links is that the problem is not that the device is locked but in fact this device acts 1st as a flash storage and then 2nd should switch to USB device but 2nd step is not happening - right ? – Boris Jan 28 '12 at 14:14
  • well truly speaking i dont know about it & that is why i have pasted the link below ... – One Zero Jan 28 '12 at 14:21
  • Disk Utility which one – One Zero Jan 28 '12 at 14:23
  • I ve used the default disk utility on Oneiric, it lists my hard disk + 16 SSD disks: from /dev/nbd0 to /dev/nbd15. Trying with GPARTED I see only my hard disk. – Boris Jan 28 '12 at 15:39
  • I m not smart enough to create a configuration for usb_modeswitch and I doubt that I need to switch from a flash device to an other kind of device because my main goal is to use it as a flash device – Boris Jan 28 '12 at 15:53

I give up:

the only way I found to make this Leapfrog Tag working is to plug it on a Windows XP PC.

This is not a real answer

I just want to record the tasks I'm using to try to solve my problem based on the wiki about Didj given by fossfreedom:

I'm trying to unlock access to the LeapFrog Tag USB:

1- install sg3_util
2- get "some" Leapfrog Didj programs (Didj seems to be an other Leapfrog USB device)

$ wget http://medialib.leapfrog.com/didj_opensource_code/Didj-Linux-4222-20090422-1236.tar.gz
$ tar -xzf Didj-Linux-4222-20090422-1236.tar.gz

3- searh the programm scsi_custom.c

$ find . -name scsi_custom.c
./Didj-Linux-4222-20090422-1236/host_tools/scsi/scsi_custom.c

4a- perhaps program needs to be customized for the Leapfrog TAG instead of the Didj device ? but I don't know what part to be modified.

4b- compile the program scsi_custom.c (with some warning unfortunately)

$ cd Didj-Linux-4222-20090422-1236/host_tools/scsi
$ gcc -o scsi_custom scsi_custom.c
scsi_custom.c: In function ‘print_reply’:
scsi_custom.c:201:3: attention : format ‘%x’ expects argument of type ‘unsigned int’, but argument 2 has type ‘long unsigned int’ [-Wformat]

5- plug the LeapFrog Tag USB and turn it on
to cross-check that the device is well plugged, I do lsusb and get something like:

$ lsusb
...
Bus 005 Device 009: ID 0f63:0700 LeapFrog Enterprises POGO

6- and here, according to the wiki, I should $tail -f /var/log/messages
but /var/log/messages does not exist.
Else trying:
- $ tail -f /var/log/dmesg does not return much
- $ dmesg | grep -i usb returns this
[20221.960029] usb 5-1: new full speed USB device number 2 using uhci_hcd

-$ dmesg | grep -i scsi returns :

[    1.228576] sd 2:0:0:0: Attached scsi generic sg1 type 0
[    1.252491] scsi 3:0:0:0: Direct-Access ATA Hitachi HDT72101 ST6O PQ: 0 ANSI: 5
[    1.252724] sd 3:0:0:0: Attached scsi generic sg2 type 0
[    1.263917] sd 2:0:0:0: [sda] Attached SCSI disk
[    1.331646] sd 3:0:0:0: [sdb] Attached SCSI disk

Note that /dev/sda and /dev/sdb are hard disk, not the USB device that I m looking for.

So I m still unable to know the /dev/sg? for my device.
So I m unable to continue this solution.

  • ... try tail -f /var/log/dmesg instead - n.b. you dont need sudo in-front of the command. – fossfreedom Jan 29 '12 at 11:36
  • I ve update the answer with tail -f /var/log/dmesg (in step 6) but it won't help I guess. Perhaps the warnings (in step 4) when compiling the scsi program are the source of the issue ? – Boris Jan 29 '12 at 12:30
  • those warnings are pretty standard fair... I doubt they are significant... in the DidJ code, are their any usb_ids in the header (.h) or code files (.c)? may be you need to add your usb_id in the code? – fossfreedom Jan 29 '12 at 12:57
  • In case anyone else is still looking at this in 2014... In Ubuntu distributions, /var/log/messages can be found at /var/log/syslog I hope that helps somebody. If anyone has some info on the LeapFrog Leap Reader, I am trying to get our grand-daughter's one working in 'buntu wish me luck! –  Nov 02 '14 at 22:27
  • @Martin thank you to keep us inform if you find a solution – Boris Nov 11 '14 at 18:02
