<p>My sister asked me to have a look at her notebook (a Medion Akoya P6612
with Windows Vista) because the CDROM drive wouldn’t work, and it was
not even displayed in the Windows Explorer. I looked into the Device
Manager and noticed that the CDROM device (TSSTCorp SN-S083a) was
displayed with a small yellow exclamation mark besides its icon, and it
said on the Properties page that the device could not be started and
referred to Code 39. Reinstalling the drivers had no effect, but after I
had a little chat with <a href="http://google.com/">Big Blue G</a>, I found a <a href="http://www.pchell.com/hardware/cd_drive_error_code_39.shtml">howto entry</a> which
suggested the following:</p>
<ol>
<li>Be logged in with an administrator account</li>
<li>Open the Registry Editor (choose it from the Start Menu or press
Win+R and type <code>regedit</code>)</li>
<li>Navigate to
<code>HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}</code></li>
<li>Then, in the right pane, delete all of the following keys:
<ul>
<li>UpperFilters</li>
<li>LowerFilters</li>
<li>UpperFilters.bak</li>
<li>LowerFilters.bak</li>
</ul></li>
<li>Restart your computer</li>
</ol>
<p>This worked fine for us.</p>

<p>…note to myself: Remove a potentially mounted SD card before suspending
your SL510, otherwise the kernel gets stuck…</p>
<p><strong>Update:</strong> Turned out the SD card was a bit buggy, the driver mostly
got a timeout when trying to speak with it.</p>

<p>Yesterday, I suddenly wasn’t able to use my AF9015-based DVB-T USB stick
anymore. It only worked for about a minute, then the image froze and
<code>dmesg</code> said the following:</p>
<pre><code>[10633.166371] usb 1-3: USB disconnect, address 5
[10633.186247] af9015: bulk message failed:-22 (8/-339951920)

[10633.186282] mt2060 I2C write failed
</code></pre>
<p>I was not even able to <code>rmmod</code> the dvb-usb-af9015 kernel module, the
rmmod process just hung itself up.</p>
<p>After two hours of compiling a new driver version, experimenting with
kernel parameters and getting a new <a href="http://www.otit.fi/~crope/v4l-dvb/af9015/af9015_firmware_cutter/firmware_files/4.95.0/">firmware
version</a>,
I finally booted into my rarely used Windows system. The first thing I
saw was the “USB 2.0 device on USB 1.1 bus”, and as I also could not get
a movie stream, I tried to plug the DVB-T stick into a different USB
port. And voilà, suddenly everything worked again, as well on Windows as
later on Linux. No more error messages in the kernel log, everything
just fine as before.</p>
<p>But I wonder if I have been using this USB port before — as far as I can
remember, the DVB-T stick had always been on the other port… Yet another
proof for me to never trust yourself <img src="https://rohieb.name/smileys/biggrin.png" alt=":D" /></p>
<p><strong>Update:</strong> Unfortunately, this solution did not help for long. After
about two weeks, the error is still there, and also occurs more
frequently, near to once an evening (until I reboot). So maybe, it
hasn’t even to do with switching USB ports, and my hardware is beginning
to fail… <img src="https://rohieb.name/smileys/sad.png" alt=":(" /></p>
<p><strong>Update:</strong> Seems it is fixed now, using revision dca0fed8d68b (Sat Sep
26 19:27:52 2009 +0200) of
<a href="http://linuxtv.org/hg/~anttip/af9015">anttip’s</a> repository. At least it
worked for over 4 hours now <img src="https://rohieb.name/smileys/smile.png" alt=":-)" /></p>
