Use simpleusb, or perhaps configure usbradio to not use PL DSP functions, will improve the ability to support multiple nodes, and have multiple nodes connected from the network at the same time. I use the Linux command "top" to show real time useage of memory and CPU %.<br><br>Thanks,<div>Bob</div><div>kk6ecm</div><div><br></div><div>Sent from iPad<div><div><br></div></div></div></div><div><br>On May 12, 2014, at 8:55 AM, Doug Crompton <<a href="mailto:doug@crompton.com">doug@crompton.com</a>> wrote:<br><br></div><blockquote type="cite"><div>

It works but it is pushing the envelope a bit both in using the hub and also two nodes.

You just need to setup another server, move you second node there and set the server iax address at <a href="http://allstarlink.org">allstarlink.org</a> and the second BBB and you Internet router. This would also have the added redundancy of another independent server. Hopefully we will get the BBB GPIO setup for PTT/COS and then you can use any compatible usb sound FOB. Then the cost of each node will be on the order of $60 or so.<br id="FontBreak"></font><br><b><font style="font-size:16pt;" size="4">73 Doug</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">WA3DSP</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4"><a href="http://www.crompton.com/hamradio">http://www.crompton.com/hamradio</a></font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div><hr id="stopSpelling">Date: Mon, 12 May 2014 11:00:59 -0400<br>From: <a href="mailto:jonathan.weirmeir@gmail.com">jonathan.weirmeir@gmail.com</a><br>To: <a href="mailto:app_rpt-users@ohnosec.org">app_rpt-users@ohnosec.org</a><br>Subject: [App_rpt-users] USB hubs with BB Black?<br><br><p dir="ltr">Good morning.</p>
<p dir="ltr">I seem to remember seeing posts recommending not using USB hubs.</p>
<p dir="ltr">However, the BeagleBone Black only has one USB host connector.</p>
<p dir="ltr">I'd like to use two URIx's with the BB Black.</p>
<p dir="ltr">Any suggestions?</p>
