From 2f5c31b0f2b8c6bfb004e24aef80c1df75452001 Mon Sep 17 00:00:00 2001 From: Andrzej Kaczmarek Date: Wed, 29 Aug 2012 10:02:09 +0200 Subject: [PATCH] Bluetooth: mgmt: Fix enabling LE while powered off commit 562fcc246ebe31ade6e1be08585673b9b2785498 upstream. When new BT USB adapter is plugged in it's configured while still being powered off (HCI_AUTO_OFF flag is set), thus Set LE will only set dev_flags but won't write changes to controller. As a result it's not possible to start device discovery session on LE controller as it uses interleaved discovery which requires LE Supported Host flag in extended features. This patch ensures HCI Write LE Host Supported is sent when Set Powered is called to power on controller and clear HCI_AUTO_OFF flag.
