I have just installed Ubuntu 14.04 LTS on a new ssd (no Windows operating system installed). Everything looks fine except that I cannot see a USB pendrive when I attach it to the usb port. How do I fix this?

First check if the usb is detected at all. Let's give you an example...
Without connecting the USB pendrive:
user@ubuntu:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mtdblock0 31:0 0 16M 0 disk
mtdblock1 31:1 0 7.5G 0 disk /
Now with the pendrive connected:
user@ubuntu:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mtdblock0 31:0 0 16M 0 disk
mtdblock1 31:1 0 7.5G 0 disk /
sda 8:16 1 63.2M 0 disk
`-sda1 8:17 1 63.1M 0 part
As you can see the pendrive is detected and assigned as /dev/sda
containing one partition as /dev/sda1
. Now it's time to check the filesystem type of this partition:
user@ubuntu:~$ sudo fdisk /dev/sda -l
Disk /dev/sda: 66 MB, 66240000 bytes
255 heads, 63 sectors/track, 8 cylinders, total 129375 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: 0x6439f37f
Device Boot Start End Blocks Id System
/dev/sda1 * 63 129338 64638 af HFS / HFS+
This specific USB pendrive has a Mac Os Extended (journaled) partition. In this case to be able to mount this partition for further read/write operations in Ubuntu you will need to install according filesystem support for that:
sudo apt-get install hfsprogs
For exFat:
sudo apt-get install exfat-fuse exfat-utils
and so on...
