test passing _Driver tests after only one device (#83)

Up until now I've always required that all matched / found HardwareIDs
in a _Driver test pass their tests for the overall _Driver test to pass,
but #83 shows this might not be correct. This adds a test variable to
easily compare results with the old vs this approach to test regressions
