Type I X-ray bursts are believed to be caused by unstable burning on the surface of a neutron star in a binary system. In this paper we examine the Unconventional Stellar Aspect (USA) experiment archive of binary neutron star and Black Hole Candidate (BHC) data for evidence of X-ray bursts. We scanned 927.5 ks of neutron star data and found 19 Type I X-ray bursts, yielding an average burst rate λ = 2.05*E-2 bursts/ks, or 48.8 ks between bursts. We scanned 972.3 ks of BHC data and found no evidence for X-ray bursts, yielding a 95% confidence limit of <= 3.1*E-3 bursts/ks, or >325 ks between bursts, on the rate of X-ray bursts in BHCs. We discuss how this provides evidence against the presence of a surface on the compact object in these systems.
