Thanks to Lennart and William, I can put the image on the loopback
interface, but it I sadly no further ahead.  Here's what happens:

losetup /dev/loop0 usb.img
fdisk -u -l /dev/loop0

Disk /dev/loop0: 4041 MB, 4041211904 bytes
255 heads, 63 sectors/track, 491 cylinders, total 7892992 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: 0xb8167e71

Disk /dev/loop0 doesn't contain a valid partition table

mount /dev/loop0 /mnt/tmp/
NTFS signature is missing.
Failed to mount '/dev/loop0': Invalid argument
The device '/dev/loop0' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

This is where I got stuck before - I can't mount the image because it is
broken, but I don't know how to fix its brokenness.

Any other suggestions?
