I use the TBS 6981, originally with the TBS linux
drivers, but am now using the open source drivers
in the latest kernels (3.12 and on from memory).<br>
<br>
The TBS linux drivers do work, but use a very old
version of the media software stack, which can
cause problems if you have devices from other
suppliers.<span class="HOEnZb"><font

Scott, I've just upgraded from Xubuntu 12.04 to 14.04 and
tried to get my TBS 6981 to work with the kernel drivers
(3.13.0.x). No luck. /var/log/syslog reported that the
the 'on demand' firmware didn't load.<br>
<br>
Can you let me know what steps you went through to get
this working? And what Os are you running?<br>
<br>

I'm reasonably sure that I had done these things.<br>
I believe the TBS 6891 uses the cx23885 chipset/firmware, not
the cx24117.<br>
<br>
The files '<span class="pln">v4l</span><span class="pun">-</span><span
class="pln">cx23885</span><span class="pun">-</span><span
class="pln">avcore</span><span class="pun">-</span><span
class="lit">01.fw</span><span class="pln"></span>' and '<span
class="pln">v4l</span><span class="pun">-</span><span
class="pln">cx23885</span><span class="pun">-</span><span
class="pln">enc</span><span class="pun"></span><span
class="lit">.fw</span>' were already in /lib/firmware (from
the 12.04 installation using the TBS drivers) and I copied '<code>dvb-fe-cx24117.fw</code>'
to /lib/firmware having followed the instructions at <a
moz-do-not-send="true" class="moz-txt-link-freetext"
href="https://github.com/ljalves/linux_media/wiki/CX24117-firmware">https://github.com/ljalves/linux_media/wiki/CX24117-firmware</a>.<br>
<br>
Is there more to installing the firmware than just 'sudo cp <span
class="pln">v4l</span><span class="pun">-</span><span
class="pln">cx23885</span><span class="pun">-</span><span
class="pln">avcore</span><span class="pun">-</span><span
class="lit">01.fw</span><span class="pln"> /lib/firmware'?</span><br>
<br>
I will try again (though not until next weekend)<br>
<br>
Thanks for the advice,<br>

I presume you did a reboot after copying the firmware to
/lib/firmware.<br>
<br>
If you open a terminal and do 'dmesg | grep frontend' you
should see something similar to:<br>
</small></small><br>

</small></small><br>
<small><small>Note your adapter numbers (4 & 5 in my case)
may be different (0 &1) if no other dvb devices on

<br>
You should also see something like this if you do 'dmesg
|grep firmware' :<br>
<br>
[ 11.957967] usb 1-2: r8712u: Loading firmware from

The above were done on a fresh install of Myhthbuntu 14.04,
with mythtv master (0.28-pre).<br>

I'm following this with interest as I have a TBS 6891 (and a TBS
6991) and would like to use the kernel drivers. Shouldn't this
work on 12.04 with 3.2.0-63-generic-pae? 'dmesg | grep frontend
and 'dmesg |grep firmware' return nothing.<br>

Richard,<br>
<br>
No chance with 3.2 series kernel, minimum kernel which includes the
open source driver for TBS 6981 is 3.12.<br>
<br>
I am not aware of open source driver, in or out, of kernel for TBS
6991.<br>
