USB Cable has four wires inside of it — usually, it's a red, green, white, and black cord.
* Red color indicates the positive wire with 5 volts of DC power.
* Black has always been the ground wire in almost all electronic devices.
* White is the data as a "positive" wire, while
* Green is also for the data , but as the negative wire.

If USB cable has color combinations, like orange, blue, white, and green then -
* Orange is the positive, with 5 volts of power in the DC (direct current).
* White indicates a ground wire, meaning the negative wire.
* Blue corresponds to the negative data
* Green as the positive data.

VirtualBox defaults to using the CDROM/DVD drive which is pretty worthless unless you have a supply of blanks, I don't have many on hand presently. I have been trying to make the USB function work without much success.

Googling suggests group/user problems, I have myself and root listed as vboxusers. The GUI has a USB menu which is always grayed, where I can create a filter, it recognizes the Sandisk flash drive when entered, I click on OK and nothing is saved apparently.

Now I've run across something in google that suggests an entry in fstab may be required? Has any one worked through this maze who can suggest how to make it work?

I have a running Fedora 21 system. I would like to make a backup of it to a USB drive, a clone that can be booted. I know how to do all the "normal" stuff (partition, LVM, mkfs, rsync, and GRUB), but I'd like the USB drive to be encrypted, and I don't know how to set that up manually (I haven't messed with encrypted filesystems under Linux before).

The system I'm backing is also headless, so no GUI tools. Any Pointers, tips, suggestions?
