我找不到 0a5c:2045 对应的 Windows 十六进制文件来尝试此解决方案:https://github.com/advancingu/XPS13Linux/issues/1
根据要求的日志lspci -knn | grep Net -A2; lsusb

答案1
BCM2045 存在一个问题,最近已在上游修复,我已将补丁应用到内核源代码中
sudo apt-get install build-essential linux-headers-$(uname -r)
wget https://www.dropbox.com/s/y4c8nm8fr1f2amx/bluetooth-4.2.tar.gz
tar -zxvf bluetooth-4.2.tar.gz
cd bluetooth
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo mv /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko /lib/modules/(uname -r)/kernel/drivers/bluetooth/btusb.ko.bak
sudo cp btusb.ko /lib/modules/4.2.0-18-generic/kernel/drivers/bluetooth/btusb.ko
重新启动并查看它是否能解决蓝牙问题,如果确认可以正常工作,我可以制作一个 DKMS 版本,当您更新到较新的内核时无需重新编译
