Linux 无法识别蓝牙适配器解决办法

蓝牙适配器(USB):胜为 UDC-321

Linux 2.6.29

首先查看USB是否识别:

#lsusb

Bus 005 Device 004: ID 0402:5602 ALi Corp. Video Camera Controller
Bus 005 Device 003: ID 05e3:0718 Genesys Logic, Inc.
Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 015: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 046d:c062 Logitech, Inc.
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

说明USB正确识别。

查看系统的蓝牙设备:

#hciconfig -a

该命令没输出。

注:hciconfig 等命令属于 bluez-utils,Debian 系统可以使用 apt-get install bluez-utils 安装

查看系统设备:

可以看到,原因是没有找到相应的驱动。经查,是因为linux 2.6.29没有hci_usb驱动所致。

解决办法,从2.6.27版本及以前的版本中,获取

/drivers/bluetooth/hci_usb.c and hci_usb.h

/drivers/bluetooth/hci_usb.c and hci_usb.c
