As reported by the NOAD in a note about the use of used :

There is sometimes confusion over whether to use the form used to or use to, which has arisen largely because the pronunciation is the same in both cases. Except in negatives and questions, the correct form is used to : we used to go to the movies all the time (not we used to go to the movies ). What is the correct form in a negative that uses the auxiliary verb do? (not I didn’t like mushrooms)

About the negative of used to, the NOAD reports the following note: Traditionally,

used to behaves as a modal verb so that questions and negatives are formed without the auxiliary verb do, as in it used not to not be like that and used she to come here? In modern English, this question form is now regarded as very formal or awkwardly old-fashioned, and the use with do is broadly accepted as standard, as in did she use to come here? Negative constructions with do, on the other hand (as in it didn’t used to be like that) although common, are informal and not generally accepted.
