我制作了一个 dkms deb 文件，其中包含一个已修补的 btusb.c 文件，因此蓝牙可以正常工作
wget https://www.dropbox.com/s/6yau4ieg6iv47xo/btusb-dkms_3.0_all.deb
dpkg -i btusb-dkms_3.0_all.deb
wget http://www.gnebehay.com/blog/lenovo-flexpad-bluetooth-debian/BCM43142A0-105b-e065.hcd
sudo cp BCM43142A0-105b-e065.hcd /lib/firmware/brcm/dmesg | egrep -i 'blue|firm'如果不起作用，请重新启动并发布结果
