I want to probe these 4 SCC ports against 2 serial drivers (e.g. async and sync). Each port is declared as compatible with the 2 drivers. When the first driver is loaded, all devices are probed and bound with this driver and cannot be probed against the second driver. I know that it can be a way to prevent against concurrent accesses but the configuration is static and depends on how the drivers are loaded. In fact, I want to load my 2 drivers, probe each entry without requesting any resource then select how to open my ports using the first or second driver. Any tips ? Thanks Laurent
