I know this question has been asked before, but following those answers does not seem to work for me.

I have created an image of a USB stick this is on my laptop harddrive. How do I mount this image?

The command I used to create the image was:

ddrescue --no-split /dev/sdb usb_recovered usb_recovery_log

What am I supposed to do next? Mount it? Fix it then mount it? Mount it then fix it? And how?

UPDATE:

What I want to recover are the files in the image. How? I don't know as I have tried testdisk and it can't find partitions, and I have tried fdisk and it can't find a partition table in the image either.
