I think the first sign of trouble is the FAT: and
then the VFS: lines.
1)  Do you know if there is a valid partition table
on the device?  Ask 
if you need help determining.
   

yes, I need help to determine
 

Do a "fdisk -l /dev/sda".  That is of course assuming that your other 
device has become /dev/sda instead.  Adjust name if necessary.

It might be enlightening to do this for the device that works also.  
Compare your results between the two.


2)  Are you successfully using this device on any
other machine?  Could 
you provide details?
   

I don't use this device in other machine but i connect
other flash driver (generic) in my pc and it's ok.
 

Seeing you do not use this device elsewhere, it remains quite possible 
that your partition table, or lack of one, is the source of the problem.

Do you have / Have you ever had  any data on this unit?
3)  Are you doing a mount command or is the mount
being attempted 
automatically?
   

I do manual mount and automatic mount with
usb-storage.
 

What is your mount command line that you try?   What is the response?
 

4)  Do you know what filesystem is on the device?
   

No, i don't now what filesystem use it.
 

We can get to this based on results and answers from above suggested 
actions and questions.

The reason I ask about the partition table is that
what I have seen is 
more along these lines (of course this is a usb hard
disk enclosure, not 
a flash drive):
