From 6967b4d9de4a7cf3b00cd9a93981d3206d75a1d8 Mon Sep 17 00:00:00 2001 From: Henrik Rydberg Date: Wed, 23 Jun 2010 09:31:37 -0700 Subject: Input: hid-input - use a larger event buffer for MT devices The MT devices produce a lot of data. Tell the underlying input device approximately how many events will be sent per synchronization, to allow for better buffering. The number is a template based on continuously reporting details for each finger on a single hand.
