Is this a valid use of どころか?


In the following, I feel it should be 会話が出来 **る** どころか.

> ジムは日本語で会話が出来ないどころか、簡単な挨拶も出来ない。  
>  Jim is not only unable to converse in Japanese; he cannot even make simple
> greetings.

I was expecting the sentence to end talking about how well Jim can speak
Japanese. If this is a valid usage, can you please give a more literal
translation?




It is not unseen, but it is incorrect, or at least different from the
traditional usage of どころか. As you said, the correct expression is

> ジムは日本語で会話が **できる** どころか、簡単な挨拶もできない。

Another correct way is

> ジムは日本語で会話ができない **ばかりか** 、簡単な挨拶もできない。
