藍牙滑鼠

為什麼我無法連接以下滑鼠：

# lsusb
...
Bus 001 Device 002: ID 19ff:0239 Dynex
...

設備 2，控制器，在使用 Hex ID 進行Google搜尋後工作正常（請參閱答案：韌體更新以了解我是如何工作的，以防你好奇。這就是我難過的地方。使用Gentoo 藍牙 Wiki和Arch 藍牙滑鼠頁面，以下是我得到的輸出blutoothctl：

請注意藍牙滑鼠 M336/M337/M535 的 NEW、CHG 和 DEL 線（我僅在按下配對按鈕時才會收到 NEW、CHG 和 DEL 線）。每次我嘗試連接信任或配對項目時，我都會收到：

[bluetooth]# pair 34:88:5D:87:C7:CE
Device 34:88:5D:87:C7:CE not available

我正在嘗試將我的外圍設備轉換為藍牙以節省我的前端 USB 埠。在我有一個工作滑鼠之前，我不敢嘗試我的新耳機。

今天看包裝，滑鼠正式包裝為羅技M535藍牙滑鼠

問題解決了，我錯過了藍牙 Wiki 中的一步。將我的使用者添加到 plugdev 組：

usermod -a -G plugdev ecyoung
