From 5691c8473936508c51639b6ff8467e55d8b129c1 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Wed, 19 Apr 2006 20:40:01 -0300 Subject: V4L/DVB (3819): Cxusb-bluebird: bug-fix: power down corrupts frontend This patch prevents a bug where the frontend is unable to tune after waking from powered down state. Now, the device remains powered on until it is disconnected, just like the windows driver. It seems that the bluebird firmware is unable to successfully handle tuning after a powered down state. This patch fixes all of the FusionHDTV Bluebird USB2 devices. The Medion MD95700 will still behave as before, since it was unaffected by this bug.
