"Didn't use to" vs. "didn't used to"

Hey my great teachers here!!

As I have read one book I have individually found a strange usage of USE TO structure. They are:

1, He didn't used to come here very often.
2, He didn't use to come here very often.

Is there any different between the both? Why after used to is used after auxi didn't?

Thanks beforehand!!!

Basically, they are spelling variations. Both forms are common and casual.

Look in Swan's Practical English Usage, Jamie, under 'used + infinitive'.

Oops! Where'd he go? Curiouser and curiouser...
