我使用的是 ubuntu 18.04 和带无线接收器的 logitech m195。之前我遇到了 usb 2.0 问题,因为鼠标时不时会冻结(冻结时没有恢复选项)。
我尝试了各种方法,特别是关闭自动 USB 挂起功能并更新到新内核(包括最新的 5.2.8),希望能够修复罗技无线支持的一些问题。但这些方法都无济于事。鼠标只有在 USB 3.0 端口上才能正常工作。
然而,在 ubuntu 更新了最新的软件包后,问题也影响到了 usb 3.0 端口。鼠标时不时会冻结。唯一的区别是,usb2.0 没有解冻选项,而现在使用 usb 3.0 端口时,这种冻结有时会持续,有时鼠标会在几秒钟后开始工作。
当鼠标正常工作时,我得到以下信息
dmesg |tail

但是在冻结期间我收到以下消息

更具体地说,冻结意味着鼠标停止工作。Ubuntu 运行正常,我仍然可以使用触摸板移动指针。
任何帮助都将不胜感激。:)

有报道称,由于射频干扰,罗技品牌无线鼠标不喜欢 USB 3.0 插头。解决建议包括通过加密狗连接 USB 接收器,使其远离射频干扰源。我还注意到,当空调或附近的风扇运转时,我的鼠标更容易冻结。更多证据表明射频干扰是罪魁祸首(或责怪罗技没有制造更好的接收器天线)。
