From 6a744bb95f239181316207f4520b5955483df914 Mon Sep 17 00:00:00 2001 From: Michael Gernoth Date: Thu, 5 Nov 2015 21:50:29 +0100 Subject: [PATCH] hmland: decrease poll-timeout to 250ms Send a NULL-frame to the hmcfgusb at least every 250ms, this seems to improve behaviour on the Raspberry Pi and should not really introduce overhead.
