我在运行 Ubuntu 12.04.2 LTS 的 HP Proliant N40L 微型服务器中安装了两个独立的 PCI 电视调谐卡。 两张卡均被成功识别并注册为 DVB-T 卡
尝试使用 DVB 实用程序（scan、w_scan）或其他软件（TVHeadend）没有返回信号。dmesg 中没有错误消息（见下文）。其中一张卡已成功插入同一根天线电缆的 Windows PC 中，因此我相信硬件和信号都没有问题。
解决该问题的下一步是什么？

答案1
我有一个泰拉泰克 Cinergy TStick+（ID 0ccd:00d7）。
所有品牌/设备驱动程序似乎都不起作用，我不得不使用媒体构建：
（链接提供安装“Media Build”驱动程序的步骤。）
出现在系统盘，有此设备吗？
您能否提供以下输出：
lsusb
lsmod | grep dvb
dmesg | grep dvb
