From 7a9d4020533b5c0c615b6de3be154c9ff30b8cc9 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 30 Nov 2008 12:17:26 +0100 Subject: Bluetooth: Send HCI Reset command by default on device initialization The Bluetooth subsystem was not using the HCI Reset command when doing device initialization. The Bluetooth 1.0b specification was ambiguous on how the device firmware was suppose to handle it. Almost every device was triggering a transport reset at the same time. In case of USB this ended up in disconnects from the bus. All modern Bluetooth dongles handle this perfectly fine and a lot of them actually require that HCI Reset is sent. If not then they are either stuck in their HID Proxy mode or their internal structures for inquiry and paging are not correctly setup. To handle old and new devices smoothly the Bluetooth subsystem contains a quirk to force the HCI Reset on initialization. However maintaining such a quirk becomes more and more complicated. This patch turns the logic around and lets the old devices disable the HCI Reset command. The only device where the HCI_QUIRK_NO_RESET is still needed are the original Digianswer devices and dongles with an early CSR firmware. CSR reported that they fixed this for version 12 firmware. The last official release of version 11 firmware is build ID 115. The first version 12 candidate was build ID 117.

This patch turns all BT_DBG() calls into pr_debug() to support dynamic debug messages. As a side effect all CONFIG_BT_*_DEBUG statements are now removed and some broken debug entries have been fixed.
