Hi,
From this segment of code in linux-2.6.10/drivers/usb/input/usbmouse.c:
input_report_key(dev, BTN_LEFT, data[0] & 0x01);
input_report_key(dev, BTN_RIGHT, data[0] & 0x02);
input_report_key(dev, BTN_MIDDLE, data[0] & 0x04);
input_report_key(dev, BTN_SIDE, data[0] & 0x08);
input_report_key(dev, BTN_EXTRA, data[0] & 0x10);
input_report_rel(dev, REL_X, data[1]);
input_report_rel(dev, REL_Y, data[2]);
input_report_rel(dev, REL_WHEEL, data[3]);
I didn't find any implementation that related with an absolute usb mouse. Does
this mean that
linux doesn't support absolute usb mouse? If not, what I should map an absolute
mouse data,says it
is (x,y)=(1000,2000), to the X screen size 1024*768? Is there a standard?
Thanks.
