Microsoft Access with Unicode Error

In earlier versions of CF, I could setup a datasource for a MS Access file using driver type Microsoft Access with Unicode by simply providing a name and the path to the mdb file. But in CF10 I get the error:

Connection verification failed for data source: <datasource name>

com.inzoom.jdbcado.JdbcAdoException: Must specify data source property in connection string

The root cause was that: com.inzoom.jdbcado.JdbcAdoException: Must specify data source property in connection string.

What am I missing?
