A memory leak occurs when you perform some operations on a storage device or on a USB HID that is inserted into a Windows Embedded CE 6.0 R3-based device
System TipThis article applies to a different operating system than the one you are using. Article content that may not be relevant to you is disabled.
You insert one of the following devices into a Windows Embedded CE 6.0 R3-based device:
A storage device. For example, an SD card or a CF card.
A USB human interface device (HID). For example, a USB keyboard or a USB mouse.
You perform one of the following operations:
You remove and then reinsert the storage device or the USB HID device quickly.
You suspend and then resume the Windows Embedded CE 6.0 R3-based device.
In this scenario, some event handles are not freed. If you repeat one of the operations frequently, a memory leak occurs in the File System Disk Manager (FSDMGR) functions or in the USB stack. This causes the performance of the device to decrease.
This issue occurs because the function that unmounts the partitions is not called after the storage device is removed and reinserted, and before the PnPUnloadDelay subkey times out.
A memory leak in the USB stack
This issue occurs because some event handles were recreated without freeing the existing handle instances during the resume cycle.
