STREAMS Modules                                        usbwcm(7M)



NAME
     usbwcm - STREAMS module for Wacom USB Tablets

SYNOPSIS
     # include 

DESCRIPTION
     The usbwcm STREAMS module processes byte  streams  generated
     by a Wacom USB tablet.


     The usbwcm module must be pushed on top  of  the  HID  class
     driver.  See hid(7D). The usbwcm module translates data from
     Wacom USB tablet into formatted  events  expected  by  Wacom
     X.org  XInputdriver. The event structure is the same as that
     of FreeBSD uwacom driver.

  Event Structure
     The     event_input     structure     is     defined     in:
     usr/include/sys/usb/clients/usbinput/usbwcm/usbwcm.h

          struct event_input {
       #if defined(_LP64) || defined(_I32LPx)
             struct timeval32 time;
       #else
             struct timeval time;
       #endif
             uint16_t type;
             uint16_t index;
             int32_t value;
          };


     time     The event's timestamp. When the event occurred. The
              timestamp is not defined to be meaningful except by
              being compared with other input event timestamps.


     type     The event's unique type: button,  relative/absolute
              valuator,  sync,  and  so  forth. type is among the
              following: EVT_SYN, EVT_BTN, EVT_REL,  EVT_ABS  and
              EVT_MSC.


     index    The event's sub-type. The index in a  button  event
              identifies which button status was changed. Typical
              button   index   includes:   BTN_LEFT,   BTN_RIGHT,
              BTN_MIDDLE,   BTN_SIDE,   BTN_EXTRA,  BTN_TOOL_PEN,
              BTN_TOOL_ERASER,   BTN_TOOL_PAD,    BTN_TOOL_MOUSE,
              BTN_TIP, BTN_STYLUS_1, BTN_STYLUS_2

              For  absolute  valuators,  index   is   among   the

              following:  ABS_X,  ABS_Y,  ABS_Z,  ABS_RX, ABS_RY,
              ABS_WHEEL, ABS_PRESSURE, ABS_DISTANCE,  ABS_TILT_X,
              ABS_TILT_Y, and ABS_MISC.


  Ioctls
     EVTIOCGVERSION    The argument is a pointer to an int.  This
                       option  returns the current version of the
                       event interface implemented by the STREAMS
                       module.


     EVTIOCGDEVID      The argument is a pointer to  event_dev_id
                       structure. This ioctl returns the identif-
                       iers of the device.

                         struct event_dev_id {
                         uint16_t bus;
                         #defineID_BUS_USB 3
                         uint16_t vendor;
                         uint16_t product;
                         uint16_t version;
                         };



     EVTIOCGBM         The argument is a pointer to an  variable-
                       length  char array. This ioctl returns the
                       event types reported by device:

                       EVT_SYN,   EVT_BTN,   EVT_REL,    EVT_ABS,
                       EVT_MSC


     EVTIOCGABS        The  argument   is   a   pointer   to   an
                       event_abs_axis   structure.   This   ioctl
                       returns the ranges, and  other  parameters
                       for the specified axis.

                         struct event_abs_axis {
                         int32_t value;
                         int32_t min;
                         int32_t max;
                         int32_t fuzz;
                         int32_t flat;
                         };
