47: Change History (most recent first):
48:
49: <USB23> 6/18/98 BWS fixed interrupt refcon support
50: <USB22> 6/18/98 CJK change retry to 3. add refcon to mouse data struct
51: <USB21> 6/16/98 CJK change FindHIDInterfaceByProtocol to FindHIDInterfaceByNumber
52: <USB20> 6/11/98 CJK Remove driverentry routine (not needed or used).
53: <USB19> 6/8/98 CJK change SetParamBlock function name to InitParamBlock. Remove
54: unneeded xxget... functions
55: <USB18> 5/26/98 CJK add prototype for SetParamBlock
56: <USB17> 5/15/98 CJK Increase size of HID Report.
57: <USB16> 5/4/98 CJK add IntRead req count setup field
58: <USB15> 4/26/98 CJK add setidle back in. This seems to solve periodic stall
59: problems.
60: <USB14> 4/26/98 CJK increase retry count to 10
61: <USB13> 4/24/98 CJK Change cursor device field name in mouse data structure to be
62: "CursorDeviceInfo"
63: <USB12> 4/23/98 CJK update to new style of setting bmRequest
64: <USB11> 4/9/98 CJK remove include of USBClassDrivers.h, USBHIDModules.h, and
65: USBDeviceDefines.h
66: <10> 4/8/98 CJK add saved interrupt routine proc pointer
67: <9> 3/26/98 CJK fix delay callback depth problem
68: <8> 3/25/98 CJK add interrupt states to enum
69: <7> 3/17/98 CJK Remove comma from last enum item. Update function prototypes
70: using extractprototypes tool.
71: <6> 3/2/98 CJK Add include of USBHIDModules.h. Remove include of HIDEmulation.h
72: <5> 2/18/98 CJK Add cursor device structure
73: <4> 2/11/98 CJK remove unneeded state values.
74: <3> 2/9/98 CJK Change Interface Descriptor field in mouse paramblock to be just
75: a single interface.
76: <2> 2/9/98 CJK Add InterfaceEntry function prototype
77: <1> 12/17/97 CJK First time checkin
