Franz, There is a chance that your dock is broken-- Do you have a way to test with another shimmer dock then you can confirm my suspicion. I think that either a connector pin has opened or your dock may have shipped from the factory without the proper factory EEPROM image lopaded for the SD media controller (in the dock). One of the settings in the EEPROM sets whether SD WP is logic high or logic low.
I'm going to move this thread to [email protected] and then you can report back to the list after the issue is resolved.
