A \fBUSB\fR mouse is a member of the Human Interface Device (HID) class and the \fBusbms\fR module supports only the mouse boot protocol defined in the \fBHID\fR specification. .sp .LP The \fBusbms\fR module must be pushed on top of the \fBHID\fR class driver (see \fBhid\fR(7D)). In the \fBVUID_FIRM_EVENT\fR mode, the \fBusbms\fR module translates packets from the \fBUSB\fR mouse into Firm events. The Firm event structure is defined in \fB\fR\&. The \fBSTREAMS\fR module state is initially set to raw or \fBVUID_NATIVE\fR mode which performs no message processing. See the \fIHID 1.0\fR specification for the raw format of the mouse packets. To initiate mouse protocol conversion to Firm events, change the state to \fBVUID_FIRM_EVENT\fR. .sp .LP When the usb mouse is opened or hot plugged in, the MOUSE_TYPE_ABSOLUTE event (Firm event) is sent to the upper level to notify the VUID application that it is the absolute mouse. .SH IOCTLS .sp .ne 2 .mk .na \fB\fBVUIDGFORMAT\fR \fR .ad .RS 16n .rt This option returns the current state of the \fBSTREAMS\fR module. The state of the \fBusbms\fR \fBSTREAMS\fR module may be either \fBVUID_NATIVE\fR (no message processing) or \fBVUID_FIRM_EVENT\fR (convert to Firm events). .RE .sp .ne 2 .mk .na \fB\fBVUIDSFORMAT\fR \fR .ad .RS 16n .rt The argument is a pointer to an \fBint\fR. Set the state of the \fBSTREAMS\fR module to the \fBint\fR pointed to by the argument. .RE .sp .in +2 .nf typedef struct vuid_addr_probe { short base; /* default vuid device addr directed too */ union { short next; /* next addr for default when VUIDSADDR */ short current; /* current addr of default when VUIDGADDR */ } data; } Vuid_addr_probe; .fi .in -2 .sp .ne 2 .mk .na \fB\fBVUIDSADDR\fR \fR .ad .RS 14n .rt The argument is a pointer to a \fBVuid_addr_probe\fR structure. \fBVUIDSADDR\fR sets the virtual input device segment address indicated by base to next. .RE .sp .LP If base does not equal \fBVKEY_FIRST\fR, \fBENODEV\fR is returned. .sp .ne 2 .mk .na \fB\fBVUIDGADDR\fR \fR .ad .RS 14n .rt The argument is a pointer to a \fBVuid_addr_probe\fR structure. Return the address of the virtual input device segment indicated by base to current. .RE .sp .LP If base does not equal \fBVKEY_FIRST\fR, \fBENODEV\fR is returned. .sp .ne 2 .mk .na \fBVUIDGWHEELCOUNT\fR .ad .sp .6 .RS 4n This ioctl takes a pointer to an integer as argument and sets the value of the integer to the number of wheels available on this device. This ioctl returns 1 if wheel(s) are present and zero if no wheels are present. .RE .sp .ne 2 .mk .na \fBVUIDGWHEELINFO\fR .ad .sp .6 .RS 4n This command returns static information about the wheel that does not change while a device is in use. Currently the only information defined is the wheel orientation which is either VUID_WHEEL_FORMAT_VERTICAL or VUID_WHEEL_FORMAT_HORIZONTAL. If the module cannot distinguish the orientation of the wheel or the wheel is of some other format, the format is set to VUID_WHEEL_FORMAT_UNKNOWN. .sp .in +2 .nf typedef struct { int vers; int id; int format; } wheel_info; .fi .in -2 The ioctl takes a pointer to "wheel_info" structure with the "vers" set to the current version of the "wheel_info" structure and "id" set to the id of the wheel for which the information is desired. .RE .sp .ne 2 .mk .na \fBVUIDSWHEELSTATE/VUIDGWHEELSTATE\fR .ad .sp .6 .RS 4n VUIDSWHEELSTATE sets the state of the wheel to that specified in the stateflags. VUIDGWHEELSTATE returns the current state settings in the stateflags field. .sp stateflags is an OR'ed set of flag bits. The only flag currently defined is VUID_WHEEL_STATE_ENABLED. .sp When stateflags is set to VUID_WHEEL_STATE_ENABLED the module converts motion of the specified wheel into VUID events and sends those up stream. .sp Wheel events are enabled by default. .sp Applications that want to change the stateflags should first get the current stateflags and then change only the bit they want. .sp .in +2 .nf typedef struct { int vers; int id; uint32_t stateflags; } wheel_state; .fi .in -2 These ioctls take a pointer to "wheel_state" as an argument with the "vers" and "id" members filled in. These members have the same meaning as that for 'VUIDGWHEEL INFO' ioctl. .RE .sp .LP \fBioctl()\fR requests for changing and retrieving mouse parameters use the \fBMs_parms\fR structure: .sp .in +2 .nf typedef struct { int jitter_thresh; int speed_law; int speed_limit; } Ms_parms; .fi .in -2 .sp .LP \fBjitter_thresh\fR is the "jitter threshold" of the mouse. Motions fewer than \fBjitter_thresh\fR units along both axes are accumulated and then sent up the stream after 1/12 second. .sp .LP \fBspeed_law\fR indicates whether extremely large motions are to be ignored. If it is \fB1,\fR a "speed limit" is applied to mouse motions. Motions along either axis of more than \fBspeed_limit\fR units are discarded. .sp .ne 2 .mk .na \fB\fBMSIOGETPARMS\fR \fR .ad .RS 19n .rt The argument is a pointer to a \fBMs_params\fR structure. The \fBusbms\fR module parameters are returned in the structure. .RE .sp .ne 2 .mk .na \fB\fBMSIOSETPARMS\fR\fR .ad .RS 19n .rt The argument is a pointer to a \fBMs_params\fR structure.
