If you use f_ext => ".csv/r", you explicitly tell the driver that the extension is required. If you add the /r, you should not add .csv to the table name. The driver will still be able to open your file, but it is not quaranteed anymore which file it opens: newCsv, newCsv.csv, or newCsv.csv.csv.

Another issue is case sensitivity. On Windows newCsv will match against any casing. On Linux you might need to check if your file name matches.

$ cat newCsv.csv
foo,bar,baz
1,2,3
$ perl -MDP -MDBI -e'my$s=DBI->connect("dbi:CSV:",undef,undef,{f_ext=>
+".csv/r"})->prepare("select * from newCsv");$s->execute;DDumper$s->fe
+tchrow_hashref'
{   bar              => 2,
    baz              => 3,
    foo              => 1
    }
$ perl -MDP -MDBI -e'my$s=DBI->connect("dbi:CSV:",undef,undef,{f_ext=>
+".csv/r"})->prepare("select * from newCsv.csv");$s->execute;DDumper$s

{   bar              => 2,
    baz              => 3,
    foo              => 1
    }
$ perl -MDP -MDBI -e'my$s=DBI->connect("dbi:CSV:",undef,undef,{f_ext=>

I see that the error message could use some improvement :)
