  We derive a criterion for the positivity of the maximal Lyapunov exponent of
generic mixed random-quasiperiodic linear cocycles, a model introduced in a
previous work. This result is applicable to cocycles corresponding to
Schr\"odinger operators with randomly perturbed quasiperiodic potentials.
Moreover, we establish an average uniform convergence to the Lyapunov exponent
in the Oseledets theorem.
