我有一台 Technotrend CT2 4650。它在 Ubuntu 16.04.02 上运行完美，据我所知，这是之前 LTS 系列的升级版。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。它再也找不到了。当然，它在 lsusb 中显示，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，dmesg 中出现以下信息：
[ 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：

据我所记得，这是或多或少在之前的 Ubuntu 安装中也出现了什么问题——我特别记得看到 CAM 的初始化……
我曾尝试手动安装所需的模块，但没有结果。
当我将 USB 电缆插入设备时，dmesg 中出现以下内容，其中已加载相关模块：
[ 3285.678512] usb 1-1.1: new high-speed USB device number 6 using ehci-pci
[ 3285.776059] usb 1-1.1: New USB device found, idVendor=0b48, idProduct=3015

[ 3285.776073] usb 1-1.1: Manufacturer: CityCom GmbH
[ 3285.776076] usb 1-1.1: SerialNumber: 20151107
与 OpenSuSE（和以前的 Ubuntu 安装）相比，这并不多。
欢迎任何指点。

升级到 4.8 修复了一些问题。原来 4.4.0 内核太旧了。
