Which parameter in HID soft driver makes it 255 touch possible?

Hi,

When I install your soft driver for mt touch support, on the system properties says that the system is 255 mt touch capable.

Which parameter of the descriptor is responsable for this?

I have used the same descriptor descibed on the inf on a custom mini virtual hid driver and the system properties reported only 1 touch capable. Is it necessary to do anything more to enable more than one touch?

Thanks,

touch count is not in descriptor. it is hard coded in the driver itself.

ok. but how is it reported to the host? which report is responsible by that?

Thanks,

With my best regards,

touch count is sent as a response to IOCTL_HID_GET_FEATURE request
