我有一台 Technotrend CT2 4650。它在 Ubuntu 16.04.02 上运行良好，据我所知，这是对之前的 LTS 系列的升级。USB 模块是 dvb_usb_dvbsky。
然后我的 SSD 崩溃了，前几天我重新安装了 16.04.02。已经没有被发现了。它当然显示在 lsusb 中，但模块似乎没有初始化它：
Bus 001 Device 003: ID 0b48:3015 TechnoTrend AG
当我 modprobe dvb_usb_dvbsky 时，这出现在 dmesg 中：
[ 175.468458] usbcore: registered new interface driver dvb_usb_dvbsky
我已经在运行 OpenSuSE 的 PC 上测试了该模块，并且在 dmesg 中出现了以下内容：

据我所知，这或多或少也出现在以前的 Ubuntu 安装中——我特别记得看到 CAM 的初始化......
我尝试手动安装所需的模块，但没有结果。
这是当我将 USB 电缆插入设备并加载相关模块时出现在 dmesg 中的内容：
[ 3285.678512] usb 1-1.1: new high-speed USB device number 6 using ehci-pci

与 OpenSuSE（和以前的 Ubuntu 安装）相比，它并不多。
欢迎任何指点。
升级到 4.8 固定的东西。原来4.4.0内核太旧了。
