Ubuntu 17.04 无法检测到外部 USB 鼠标

有人送给我这只鼠标。我宁愿不用买，因为我喜欢用礼物。

该品牌名为“Spectra”，型号为PJT-DMS811。

/var/log/syslog输出如下：

断开除鼠标之外的所有 USB 设备后，lsusb 无法检测到它。xsetpointer 没有提供任何东西。

(py3.6) ➜  ~ lsusb

我尝试过：

(py3.6) ➜  ~ egrep "Name|Handlers" /proc/bus/input/devices | egrep -B1 'Handlers.*mouse'
N: Name="ETPS/2 Elantech Touchpad"
H: Handlers=mouse0 event5

但该信息也显示未检测到鼠标。

显然，虽然这款鼠标名为 Spectra，但制造商却是 Jetion（因此我认为 PJT 的意思类似于 Product Jetion）。产品页面没有显示任何真正有用的信息。这是一家中国公司，但我找不到有关司机的任何信息。

它适用于 Windows 和 Mac OS X

作为最后的手段，请从您的电脑上拔下所有 USB 设备，拔下机器的电源，使其完全断开电源。如果是笔记本电脑，还请取出电池。

现在等待一两分钟，然后将所有东西重新连接到其状态，并再次尝试使用鼠标。
