I tried formating my USB using disks. The result was:

Error formatting volume

Error creating file system: Command-line `mkfs.vfat -I -n "sara" "/dev/sdc"' exited with non-zero exit status 1:
stdout: `mkfs.fat 3.0.26 (2014-03-07)
'
stderr: `mkfs.fat: warning - lowercase labels might not work properly with DOS or Windows
mkfs.vfat: failed whilst writing FAT
' (udisks-error-quark, 0)

Then I tried GParted and there are two options (new, information). I click on "new" and it says:

A partition table is required before partitions can be added.
To create a new partition table choose the menu item:
Device --> Create Partition Table)

Click on device, create partition table (msdos) and it gives me a message:

Input/output error during read on /dev/sdc

Retry does nothing so I press ignore and then my PC automatically removes my USB. I remove it and reconnect and still can't read my USB or see it in Files (Nautilus).


The output of lsusb

Try connecting it, then umount it then try to partition it with a "sudo mkfs.vfat -F32 -I /dev/sdX"
