However, only small code tweaks here and there are needed to make basic multitouch work. Extra logic is required for single-touch emulation of the touchpad. The changes made here take the approach that only one finger may emulate the single pointer when multiple fingers have touched the screen. Once that finger is raised, all touches must be raised before any further single touch events can be sent. Sometimes the magic trackpad sends two distinct touch reports as one big report. Simply splitting the packet in two and resending them through magicmouse_raw_event ensures they are handled properly. I also added myself to the copyright statement.

The USB HID standard is unclear and confusing on this issue. It seems to suggest that Feature reports can be sent on a HID device's Interrupt OUT endpoint. This cannot be the case because the report type is not encoded in transfers sent out the Interrput OUT endpoint. If Feature reports were sent on the Interrupt OUT endpint, they would be indistinguishable from Output reports in the case where Report IDs were not used. Further, Windows and Mac OS X do not send Feature reports out the interrupt OUT Endpoint. They will only go out the Control Endpoint. In addition, many devices simply do not hande Feature reports sent out the Interrupt OUT endpoint.

This patch removes the quirk so the hid-egalax driver can handle the device correctly. 2) The x and y coordinates sent by the screen in multi-touch mode are shifted by three bits from the events sent in single-touch mode, thus the coordinates are out of range, leading to the pointer being stuck in the bottom-right corner if no additional calibration is applied (e.g. in the X evdev driver). This patch shifts the coordinates back. This does not decrease accuracy as the last three bits of the "wrong" coordinates are always 0. 3) Only multi-touch pressure events are sent, single touch emulation is missing pressure information. This patch adds single-touch ABS_PRESSURE events.
