The latency figure depends on the module implementation. Instead of using a hardcoded value, each module should be able to specify its own value. This value is then used for calculating the minimum buffer size. Set the nominal latency of the primary (CF) module to a high value since the virtual device implementation fails CTS tests if it attempts to pretend that it provides low latency.
