Symptoms

In Windows Embedded CE 6.0 R3, the File System Disk Manager (FSDMGR) maintains a lock to synchronize access. When the FSDMGR PNP Thread mount request for a device is not returned for any reason, this blocks other operations on the FSDMgr because these operations need access to the lock that is held by the PNP Thread. Therefore, when an application calls the OpenStore, the OpenPartition, or the MountPartition API to mount another PNP device, the file system API cannot be returned.

Resolution
