Pololu USB to Serial adapter question

I'm trying to save space on a board of mine that is incorporating a BS2px by using a USB-to-serial breakout adapter board. The USB board in question is this one here: https://www.pololu.com/product/391
I'm having trouble communicating with the Stamp when I go to upload my program. I've switched the RX and TX lines around, hoping for a simple mistake like that, but to no effect. The error I get is "No Basic Stamps found on Com port #xx". I am getting both feedback and echo statuses as "Yes". The description suggests the logic levels should be compatible with the Basic Stamp but maybe I am understanding this incorrectly.
I would appreciate any advice on the issue, thanks.

If you only care about a small footprint on your board, you can use nearly any 4-pin connector to hook up an external USB serial adapter. I often use a simple 4-pin male header immediately beside the Stamp, as shown below.
However, with a module an RS-232 interface is required as mentioned.
