Nothing mounts!

DVDs and USB drives will not mount on my computer at all. This will make it impossible to back up my files when it comes time to upgrade. This problem started sometime within the last 3 weeks.

I'm using 5.5 amd64.

Can you connect a USB Pen in the computer and then type this on the terminal and paste here the output before and after connecting the device. Like this: Before:
[aliasbody@BodyMSI ~]$ ls /dev/sd*
/dev/sda  /dev/sda1  /dev/sda2  /dev/sda3
After:
[aliasbody@BodyMSI ~]$ ls /dev/sd*
/dev/sda  /dev/sda1  /dev/sda2  /dev/sda3  /dev/sdb  /dev/sdb1
And after that could you also post here the kernel you are using. Just type this and paste here the output :
uname -r
It will show something like this:
3.6.3-1-LIBRE

luther@aiwass:~$ ls /dev/sd*
/dev/sda /dev/sda1 /dev/sda2 /dev/sda5 /dev/sda6

# I plug in my USB stick:

luther@aiwass:~$ ls /dev/sd*
/dev/sda /dev/sda1 /dev/sda2 /dev/sda5 /dev/sda6 /dev/sdb
luther@aiwass:~$ uname -r
3.0.0-24-generic

UPDATE: I don't know what changed, but now I can mount most media with Disk Utility. The exception is my encrypted USB drive. Disk Utility lets me unlock it, but doesn't show a button to mount it.

Gnome does not automatically detect any media. The Removable Media settings are all set for "Ask what to do".

The device by itself is seen (it is /dev/sdb) but it looks like it does not have any readable filesystem (the first, and maybe only, one would be /dev/sdb1). Is it partitioned? What filesystem is used?

Disk Utility shows an ext2 partition. It works fine in my netbook, which runs Trisquel mini 5.5 i686.

In Disk Utility, when you select this ext2 partition, right below it should write where the partition is located. It should be similar to “Device: /dev/sdb1”.

Tell us what it's written.

You can also try do mount it manually:

sudo mount /dev/sd?? /mnt

That's very interesting. I had no idea I had to click on the partition to mount it. I don't have to do that for unencrypted drives. The device is /dev/dm-0.

At least now I can transfer files freely. Now the only problem is getting Gnome to automatically detect media.
