Hello

I am trying to encrypt a USB drive using the BBB and Debian wheezy (Kernel 
3.8.13-bone20).

So the command I try is:
cryptsetup --verbose --verify-passphrase luksFormat /dev/sda1

However I get the following errors:
Failure to communicate with kernel device-mapper driver.
Check that device-mapper is available in the kernel.
Cannot initialize device-mapper. Is dm_mod kernel module loaded?
Command failed with code 38: Cannot initialize device-mapper. Is dm_mod 
kernel module loaded?

As far as my limited Linux knowledge tells me, the respective kernel 
modules are not part of my kernel. Is that correct? Is there an easy way to 
make this work? Or do you see alternatives to encrypt USB drives?

Thanks!
