Problems with Symbols, High Severity (3)

	Change	Effect
1	1st middle parameter driver has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

	Change	Effect
1	Middle parameter p1 of type usbip_stub_driver* has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

Problems with Symbols, Medium Severity (7)

	Change	Effect
1	1st parameter driver has been removed from the calling stack.	This parameter will be ignored by the function.

	Change	Effect
1	The pointer level of return value has been decreased from 1 to 0.	Applications may try to access unallocated memory by the dereferencing of new return value and therefore cause a crash.

Problems with Data Types, Low Severity (2)

	Change	Effect
1	Field padding has been added to this type.	Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Size of this type has been changed from 3 bytes to 4 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Problems with Symbols, Low Severity (2)

	Change	Effect
1	Type of return value has been changed from usbip_stub_driver* to int.	Replacement of return type may indicate a change in its semantic meaning.
