Jaime Barron appeals from his guilty-plea conviction for possession with intent to distribute more than 500 grams but less *148 than five kilograms of cocaine. He argues that his three prior uncounseled misdemeanor convictions were ineligible for use in calculating his criminal history score because the waivers of his right to counsel in those cases were invalid. He asserts that, without the usage of these prior convictions, he should have been awarded a downward adjustment pursuant to U.S.S.G. § 5C1.2.

Barron has failed to meet his burden to show that those waivers were invalid. See Iowa v. Tovar, 541 U.S. 77, 124 S.Ct. 1379, 1390, 158 L.Ed.2d 209 (2004). The district court’s use of Barron’s prior convictions for purposes of determining his criminal history score was therefore proper. Because Barron’s criminal history score exceeded one, he was ineligible for the U.S.S.G. § 501.2(a) adjustment. Accordingly, the district court’s judgment is AFFIRMED.
