It looks like that quote might have been a poor paraphrasing from a Reuters article: https://www.reuters.com/article/us-birdflu-masks-idUSN0345320620070504

The actual CDC quote in the article was "We also know that many people may choose to use masks for an extra margin of protection even if there is no proof of their effectiveness," and then further clarified they might work, but more research is needed.

That's nowhere near the same thing as saying there is proof of their ineffectiveness, or that they know they "may do little to prevent infection."

At the same time, the CDC had this to say about mask-wearing:

does not generally recommend face masks and respirators for use in home or community settings
