<p>Dear Mr. Wilhelm, <br>
</p>
<p>thanks for your first advices. May I ask, what do you define as
"good" realtime behavior?</p>
<p>Could this "bad" realtime performanc be improved by using a
USB-adapter with a supported chipset? Or does USB (3.0) introduce
inherently bad realtime performance?<br>
</p>
<p>Kind regards, Karl Zeilhofer</p>

<pre class="moz-quote-pre" wrap="">Hallo Mr Zeilhofer,
generally the EtherCAT master should work with any Ethernet interface
which is supported by the kernel if one uses the generic driver.
Due to the fact that the generic driver uses parts of the regular
network stack, don't expect good realtime behavior with an USB connected
adapter.

<pre class="moz-quote-pre" wrap="">Hi,
has anyone experiences with running the IgH EtherCAT master via a
USB-Ethernet adapter?
I'm using one on one of my servers, which runs since years without
problems. It uses the r8152 Ethernet driver, which is not supported.
For the first tests, I don't want to configure my main Ethernet port,
which is an e1000e, on my daily working machine.
As far as I understood from the documentation, that Ethernet port cannot
be used for the daily network traffic any more, right?
If it would generally work over USB, I would buy a new adapter with one
of the supported chip sets. Any recommendations?
