Large-scale simulations have been performed on the current-driven two-dimensional XY gauge glass model with resistively shunted-junction dynamics. It is observed that the linear resistivity at low temperatures tends to zero, providing strong evidence of glass transition at finite temperature. Dynamic scaling analysis demonstrates that perfect collapses of current-voltage data can be achieved with the glass transition temperature Tg=0.22, the correlation length critical exponent \ensuremathν=1.8, and the dynamic critical exponent z=2.0. A genuine continuous depinning transition is found at zero temperature. For creeping at low temperatures, critical exponents are evaluated and a non-Arrhenius creep motion is observed in the glass phase.
