<p>Hello,</p>
<p>The following might be a problem related to unsupported devices
by the Kernel.<br>
</p>
<p>I am facing the problem described in the thread: <a
href="https://ubuntuforums.org/showthread.php?t=2342985"
rel="nofollow noreferrer">https://ubuntuforums.org/showthread.php?t=2342985</a></p>
<p>And my problem is that I don't know how to do the : <strong>quirk
HID_QUIRK_ALWAYS_POLL (0x00000400)</strong>, which is mentioned
in the above link.<strong><br>
</strong></p>
<p><code>lsusb</code> command for the 2 devices gives:</p>
<blockquote>
<p>Bus 002 Device 009: ID 046d:c404 Logitech, Inc. TrackMan Wheel</p>
<p>Bus 002 Device 010: ID 0a81:0205 Chesen Electronics Corp. PS/2
Keyboard+Mouse Adapter</p>
</blockquote>
<p><code>tlp-stat -u</code> command for the 2 devices gives:</p>
<blockquote>
<p>Bus 002 Device 009 ID 046d:c404 control = on,
autosuspend_delay_ms = -1000 -- Logitech, Inc. TrackMan Wheel
(usbhid)</p>
<p>Bus 002 Device 010 ID 0a81:0205 control = on,
autosuspend_delay_ms = -1000 -- Chesen Electronics Corp. PS/2
Keyboard+Mouse Adapter (usbhid)</p>
</blockquote>
<p><code>uname -ra</code> gives:</p>
<blockquote>
<p>Linux dell 4.13.0-39-generic #44~16.04.1-Ubuntu SMP Thu Apr 5
16:43:10 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux</p>
</blockquote>
<p>I think the problem is not related with autosuspend, but rather
with buffer overflow for the specific devices due to that they are
not supported in the kernel code.</p>
