In bacula's sources (src/findlib/fstype.c), I see that is called (line 127).

statvfs is a libc function :

int
statvfs(const char *file, struct statvfs *st)
{
    return statvfs1(file, st, ST_WAIT);
}

but I don't find sources of statvfs1 (seems to be statvfs1.S) to check
if this function call usbdevs.
