将 USB 连接到我的电脑后，我检查了输入lsusb。输出为：
Bus 001 Device 006: ID 0572:c68a Conexant Systems (Rockwell), Inc. EyeTV Stick
然后，我在终端中输入sudo apt-get update并安装sudo apt-get install w-scan。然后输入w_scan，输出如下：

然后，我尝试了另一种方法：我在终端中输入sudo apt-get install dvb-apps并Kaffeine从Ubuntu 软件。
之后，我打开 Kaffeine，在窗口顶部，我点击Television，然后在我为我所在国家的信号设置的Configure Television选项卡上。最后，在窗口顶部，点击，然后点击按钮，输出是它找不到任何频道，因此频道列表是空的。Device 1TelevisionChannelsStart Scan
我认为缺少该设备的驱动程序。有人能给我一些建议吗？
回答@chili555从评论中，我输入了lsmod | grep dvb。输出如下：

并且sudo dmesg | grep -i dvb，输出如下：

据此，固件丢失了。
按照以下步骤@chili555：重启后，我输入了sudo dmesg | grep -i dvb，输出与上面的输出相同，但没有关于固件的行。然后，我输入了w_scan，输出中出现了相同的错误，稍后我再次输入sudo dmesg | grep -i dvb，输出略有不同：“正在下载固件”...

之后，我尝试使用 Kaffeine，但仍然无法获取任何频道。
答案1
dmesg 输出表明您缺少所需的固件。请打开终端并执行以下操作：
cd /lib/firmware
sudo wget https://github.com/CoreELEC/dvb-firmware/blob/5ed22312b7a0231a982e8c253dfca4d0d291c820/firmware/dvb-demod-si2168-d60-01.fw
重新启动并显示：
sudo dmesg | grep -i dvb
