So do you expect _two_ partitions on that USB stick, one with
some MS-DOS stuff, one with Linux data? Or maybe this is some
manufacturer-supplied "recovery partition"? Or even worse, the
Linux data files are now somehow accessible via a MS-DOS file
system? I have _no_ idea if (or how) this is possible... still
if you look at the file sizes, they look all the same. Maybe
this is a mix of things that were present on the stick upon
production ("pre-formatted")?

I'll say it again: You could try to repair or reinstantiate
the ext2 file system (using Linux, it's the best guess I have),
or completely reinitialize (reformat) the file system (with
data loss).

That is how it looks to me.
