USB dongle (MTS MBlaze) doesn't mount

I bought an MTS MBlaze ultra USB dongle.

There is a manual that came with it. It asks me to plug it in, and find a media/cdrom0 directory and run a script in it.

But I can't find cdrom0 or anything like that under /media/.

What should I do?

Output of dmesg | tail :

Looking at your error message, your system is attempting to mount the device but the device is either drawing to much power from your system, or is wired wrong. If you have bought the device recently I would return it and try to get a new one. If you have made it, check your wiring. This problem has happened to me a few times, my logs looked pretty much the same.

It seems like kernal issues.Try to update your kernal,it may solve your problem.Run the below command to update your kernal,

sudo apt-get install linux-generic

After that reboot your pc.

Same thing happened with me with a Reliance dongle.

What I did for it:

just open the device on windows and on windows it will mount the device properly so that you can view the files inside the device now copy the files on another normal pendrive and just copy these files from the pendrive to your ubuntu...

Now you can install the GUI from these files(I guess they provide an installation script) and as you say that you are able to use internet from this dongle it should not create any other issue..

This trick worked for me..but still I don't know the problem with auto mounting the device.

I think it tries to run a script at mounting time which ubuntu does not allow(for security reasons but windows do!)

hope it helps!!
