带电视调谐器的笔记本电脑

我买了一台新的笔记本电脑调谐器（我认为它与本线程中的调谐器相同：http://ubuntuforums.org/showthread.php?t=2028123）。lsusb给出

 Bus 002 Device 005: ID 048d:9135 Integrated Technology Express, Inc. 
 Zolid Mini DVB-T Stick

dmesg | grep -i dvb插入 U 盘后给出

[12280.493513] dvb-usb: found a 'ITE 9135 Generic' in cold state, will try 
to load a firmware
[12280.523395] dvb-usb: downloading firmware from file 'dvb-usb-
it9137-01.fw'

我已按照我提到的上述线程中的步骤进行操作（将 .fw 文件移动到相关位置），但最终出现以下错误。我认为这个问题现在可以在更新的内核中得到解决。这件事真的解决了吗？我的系统日志尾部显示

myuser@mylap:~$ tail /var/log/syslog

interface driver it913x

我使用的内核版本是uname -a

 Linux mylap 3.2.0-35-generic-pae #55-Ubuntu SMP Wed Dec 5 18:04:39 UTC 
2012 i686 i686 i386 GNU/Linux

我似乎无法比这更进一步（我按照线程中前面的步骤并将 .fw 文件放入固件文件夹中，但仍然出现上述错误）。 Kaffeine 似乎没有拿起任何调谐器，甚至不会开始扫描。

事实证明，除了OP中的上述步骤之外，我还需要获取V4L设备驱动程序。该方法介绍如下：https://help.ubuntu.com/community/DVB-T_USB和http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

重启后

 dmesg | grep -i dvb

现在正在运行Kaffeine，选择我的设备后Configure Television会列出，我可以选择离我最近的信号源，电视就可以工作了！
