32 .Nd mouse and pointing device drivers
42 Currently there are specific device drivers for bus, InPort, PS/2, and USB mice.
44 it is accessible via the serial device driver or via
49 The user program simply opens a mouse device with a
52 mouse data from the device via
54 Movement and button states are usually encoded in fixed-length data packets.
58 The mouse drivers may have ``non-blocking'' attribute which will make
61 Mouse device drivers often offer several levels of operation.
62 The current operation level can be examined and changed via
65 The level zero is the lowest level at which the driver offers the basic
68 and state of up to three buttons at this level.
69 At the level one, if supported by the driver, mouse data is encoded

217     int resolution;  /* MOUSE_RES_XXX, -1 if unknown */
219     int level;       /* driver operation level */
227 field tells the format in which the device status is returned
235 field is the status report rate (reports/sec) at which the device will send
237 -1 if unknown or not applicable.
241 field holds a value specifying resolution of the pointing device.
254 field tells the length of the fixed-size data packet or the length
255 of the fixed part of the variable-length packet.
256 The size depends on the interface type, the device type and model, the
257 protocol and the operation level of the driver.
