See the keyboard ! 53: driver (there's a similar change in there as well). ! 54: <USB52> 10/21/98 DF Change LMGetMBState to it's new name LMGetMouseButtonState, now ! 55: we can include LowMem.h instead of LowMemPriv.h ! 56: <USB51> 10/21/98 bwm [2229080] NewWorld: whenever a mouse driver fails in an ! 57: interrupt pipe read, force the mouse button up to prevent a ! 58: possible hung system: we do this in case someone was holding the ! 59: mouse button down while the mouse was unplugged, leaving MacOS ! 60: is a somewhat constipated state. ! 61: <USB50> 8/25/98 BT Isoc name changes ! 62: <USB49> 6/22/98 CJK move cursordevice setup to InterfaceEntry, which is guarenteed ! 63: to be at task time ! 64: <USB48> 6/22/98 CJK rename FindNextEndpointDescriptor to ! 65: FindNextEndpointDescriptorImmediate ! 66: <USB47> 6/18/98 CJK update to use new style of error handling implemented in ! 67: keyboard module. ! 68: <USB46> 6/16/98 CJK change FindHIDInterfaceByProtocol to FindHIDInterfaceByNumber ! 69: <USB45> 6/15/98 CJK change transaction depth error messages so that they output the ! 70: refcon (current state machine stage) ! 71: <USB44> 6/11/98 CJK Remove driverentry routine (not needed or used). ! 72: <USB43> 6/8/98 CJK eliminate PBVERSION1 define ! 73: <USB42> 6/5/98 CJK remove ExpertStatus; too many clutter up expert log ! 74: <USB41> 5/26/98 DF Look for the incorrect vendorID (0x1452), when checking for ! 75: version 0.04 Rudi ! 76: <USB40> 5/26/98 CJK add prototype for InitParamBlock ! 77: <USB39> 5/22/98 CJK add check for the 0.04 version of the Rudi mouse. Do a SetIdle ! 78: of 50ms if found. ! 79: <USB38> 5/20/98 BT Set version 1 PB compatability ! 80: <USB37> 5/20/98 CJK change driver name from USBMouseModule to USBHIDMouseModule ! 81: <USB36> 5/15/98 CJK Things seem to have stabilized; no longer need to try various ! 82: different int read report sizes until we find the one that ! 83: works. Just use the maxpacketsize value. ! 84: <USB35> 5/13/98 CJK move DPI setting to interface entry code ! 85: <USB34> 5/11/98 CJK setidle to 0 ! 86: <USB33> 5/4/98 CJK implement adaptive reqCount. This way, when a mouse gives back ! 87: an OverRun error, the mouse driver automatically increases the ! 88: reqCount value (never exceeding the maxPacketSize). ! 89: <USB32> 5/4/98 CJK recover from repeated stalls when doing a setidle. added detect ! 90: for MS mouse, at which we ask for a 4 byte report (rather than a ! 91: 3 byte report) ! 92: <USB31> 4/29/98 CJK add break where needed ! 93: <USB30> 4/26/98 CJK Add back in SetIdle. This seems to solve the stall problem and ! 94: double click problem. ! 95: <USB29> 4/26/98 CJK change so that pipe stall clear is only called if happens as a ! 96: result of a read or open pipe. Also cleaned up transaction ! 97: depth error messages so that the user can tell if the problem ! 98: occurred in the completion or initiation routines. ! 99: <USB28> 4/24/98 CJK add call to clear pipestall by reference ! 100: <USB27> 4/24/98 CJK add call to turn on demo mode for shim-less environments. ! 101: <USB26> 4/23/98 CJK add status message to show who's driver this is... ! 102: <USB25> 4/23/98 CJK Reworked mouse module dramatically. It now 1) gets the full ! 103: configuration and looks for the mouse HID interface, 2) uses ! 104: this mouse HID interface to find the interrupt endpoint, 3) uses ! 105: the interrupt endpoint descriptor to open the the interrupt ! 106: pipe. Of note is that all the stuff to support the non-spec'd ! 107: mice has been removed. It will be added back in, either in a ! 108: different mouse module, or within this mouse module, as further ! 109: testing demands. ! 110: <USB24> 4/14/98 CJK Change to use driverservices strcpy ! 111: <USB23> 4/9/98 CJK change driver services to be a externally supplied header file ! 112: (using < & >) rather than quotes. ! 113: <USB22> 4/9/98 DF Massaged to work with MasterInterfaces ! 114: <21> 4/8/98 CJK correct mouse status & fatal error messages (should read ! 115: "mouse", not Mouse) ! 116: <20> 4/8/98 CJK add initialization of saved interrupt routine ptr. ! 117: <19> 3/31/98 CJK change error messages ! 118: <18> 3/26/98 CJK fix delay callback depth problem. Clean up USBExpertFatal ! 119: messages. ! 120: <17> 3/25/98 CJK Add support for interrupt transactions ! 121: <16> 3/17/98 CJK Replace "};" with just "}". Add parens to pragma unused ! 122: variables. ! 123: <15> 3/5/98 CJK I feel like a darn ping pong ball, changing the X-Delta & ! 124: Y-Delta checks back and forth. But now that the mouse 'skip' ! 125: problem has been resolved, let's see if I can't make both the ! 126: BTC PS/2 mouse AND the Logitech mouse work properly. See Radar ! 127: 2216777. ! 128: <14> 3/3/98 CJK change poll rate to 20ms ! 129: <13> 3/2/98 CJK change back to check for non-zero ! 130: <12> 3/2/98 CJK Add include of USBHIDModules.h. Remove include of HIDEmulation.h ! 131: <11> 2/19/98 CJK change polling rate back to 10ms. ! 132: <10> 2/19/98 CJK change back to notifying the MacOS when the deltas change from ! 133: report to report, not just when they're non-zero. ! 134: <9> 2/18/98 CJK Implement Ferg's suggestion that we notify the HID Emulation ! 135: routine if the X & Y deltas are non-zero. ! 136: <8> 2/17/98 CJK remove "" from expert fatal error calls. ! 137: <7> 2/11/98 CJK Change debugstr to expertfatal calls ! 138: <6> 2/11/98 CJK remove unneeded states ! 139: <5> 2/10/98 CJK change hid byte count from 8 to 3. No need to look at all eight ! 140: bytes as mouse reports only consist of 3 bytes. ! 141: <4> 2/10/98 CJK Remove keyboard related code ! 142: <3> 2/9/98 CJK change first state to setprotocol (when entering driver via ! 143: InterfaceEntry ! 144: <2> 2/9/98 CJK Add InterfaceEntry function ! 145: <1> 2/9/98 CJK First time check in.
