1. It does not appear to be a conviction or a crime of moral turpitude,
2. As you already know, issuance of a non-immigrant B-2 visa to the United States is always discretionary and not your right, it is a valuable privilege, therefore, honestly disclose the above record and explain it if required.
3. If your B2 visa is still valid you may enter the U.S. on it since you have not been convicted of any precluding crime, otherwise you may apply for another B-2 visa using the established process for that with full disclosures of the above.

It does not sound like the second charge was a crime of moral turpitude. So that means that you may still qualify for b1/b2. That said, the visa is discretionary, and you may face troubles when you re-enter the country and when you apply to renew it.

This answer does not create an attorney-client relationship and is not meant to be relied upon as legal advice.
If no "guilty plea" was entered at any point during the 2010 proceedings you should be ok. However the case/arrest will show up when you are fingerprinted and will likely result in a referral to secondary inspection. Consult with an immigration attorney for an in depth review.
