(It's looking for a Linux filesystem with a superblock, and not finding one.) You didn't specify what, if anything, is on the floppy you tried. It's possible to format a DOS floppy from Linux - see http://unix.stackexchange.com/questions/219533/how-to-format-720k-fat-ie-ms-dos-floppy-on-linux-using-usb-floppy-drive for an example.

This may not be quite what you meant, but ... AFAIK, many modern OSes can't use USB floppies by default (unlike FreeDOS) because they don't use the BIOS. Of course, I'd be surprised if Linux couldn't, but who knows. I vaguely remember hearing that Minix 3 couldn't, but Haiku allegedly can because some developer needed it and implemented it.

[Freedos-user] OT: USB floppy cannot read medium on modern PC and Linux.
Hi! I was asked why I cannot put FreeDOS on a floppy. Here is the reason. I just tried another floppy disk that I found. It is original from before 1995, so it may be broken. I can try to check on my 486 once it is up and running, but for now this is what I get on Linux when I put the disk into the USB floppy drive.
