我有双启动Win10-Debian11，联想Yoga slim 7 pro。在Windows系统中可以成功找到蓝牙设备，但在Debian中我看不到任何蓝牙设备。
我已经在 win 系统中关闭了蓝牙，并按照 wiki.debian 安装包中的说明进行操作bluez-firmware。
systemctl status bluetooth.service给了我以下内容：
● bluetooth.service - Bluetooth service

后
#rfkill unblock bluetooth
#systemctl restart bluetooth
#rmmod btusb
错误“无法设置模式...”消失了，但我仍然没有看到任何蓝牙设备。有任何想法吗？
