I have no problem to mount the USB pendrive from file browsers (Nemo, Nautilus, Dolphin, etc). But I have a pendrive, which cannot be mounted from the file browser. The error message is:
Not authorized to perform operation
And I found that it has a harddisk icon instead of removable media icon.
I can mount the pendrive with the root user with "mount" command.
Is there anyway to fix this problem so that pendrive will be recognised as the USB removable media instead of the harddisk?
