From fd3e91675d5c7b8c8a82af7f8e3c5d706e458791 Mon Sep 17 00:00:00 2001 From: Patrick Boettcher Date: Mon, 1 Dec 2008 10:51:14 +0100 Subject: dib0700: Stop repeating after user stops pushing button From: Devin Heitmueller A user noticed that there would continue to be 4-6 keypresses even after the user stopped holding down the button. This was because we were not reading the bulk pipe faster than the firmware was injecting information, which would result in a backlog. Make the query interval faster, and increase the number of cycles before we start repeating to compensate. Thanks to Knud Poulsen for pointing this out.

These modifications however broke the detection of Cablestar 2 DVB-C cards. The reason is that the earlier version of the driver used to retry unsuccessful i2c operations. The demodulator of Cablestar 2 cards (stv0297) seems to be very dependent on these retries and adding them back fixes Cablestar detection. This patch restores this behaviour for the CableStar2.
