I have a problem. I have had Ubuntu 12.04 on my laptop for 2 years and up until now no problems with the USB. But since this evening the pc doesn't mount the USB. I read some discussions but the problem persists. with
sudo fdisk -l
shows
Disk /dev/sdb: 2003 MB, 2003828736 bytes
43 heads, 42 sectors/track, 2167 cylinders, total 3913728 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00095b2e
My USB has got fat32
filesystem:
And with a USB with ext4
filesystem,shows:
Disk /dev/sdb: 31.5 GB, 31457280000 bytes
255 heads, 63 sectors/track, 3824 cylinders, total 61440000 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000eecfd
So the Pc sees that the USB is connected but I don't see it in file directory.
Where data is a partition of my SSD.
whitsudo lsusb
command:

Where the last line is the 2GB USB I have Arduino and it works without problems. with the other pc in my house, with ubuntu too the USB are read perfectly. How can I solve my problem?
