You seem to be correct, the in-kernel NTFS driver does not seem to know
how to deal with files with ':' in the filename.  I tried with the
NetBSD and (gnu)coreutils and findutils, none of them could get any
usable information about that file.

This limitation seems to be in the NTFS code, as I can
create/edit/copy/etc/ a file with that name on an FFS mount without any
issues.

I was able to install the fuse-ntfs-3g stuff out of pkgsrc and it was
able to mount the NTFS formatted USB stick and then I was able to access
the file as 'file\:.ext' and copy it off.

I know your subject line said 'not fuse', but that might be the only way
to get this file off the USB stick and onto your NetBSD system.
