PC or Beagle Bone Black? etc. Also usbradio or simpleusb?<br><br>This is a common problem on the URI with external EMI and power spikes. <br><br>The problem can be fixed. You need to ground everything and eliminate EMI as much as possible. <br><br>The other issue is the USB not resetting when it has this problem. Most of the PC's will but probably not all. The next version of the BBB code coming out soon will reset fine. <br><br>If you are using simpleusb there is a bug in the code that precludes a reset upon USB interruption. This fix will also be in the BBB code that is coming soon. If you want to fix a PC simplesusb installation here is the link -<br><br> <a href="http://www.crompton.com/hamradio/BeagleBoneBlackAllstar/simpleusb-howto.pdf" target="_blank">http://www.crompton.com/hamradio/BeagleBoneBlackAllstar/simpleusb-howto.pdf</a><br><br>See how to do the patch at the end of the pdf.<br><br>You should be able to pull the USB cable from the URI while in use (green light flashing normally) and reinstall the USB and it should start flashing again. If not then your system will not recover from USB EMI hits properly. <br><br>It is always a good idea to try and fix or reduce the problem because in severe cases it would be resetting all the time. It sounds like you case is less severe.<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">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div>> Date: Sat, 20 Sep 2014 12:24:15 -0500<br>> From: n9udo@yellowthunder.org<br>> To: app_rpt-users@ohnosec.org<br>> Subject: [App_rpt-users] URI Problem<br>> <br>> Has anyone run across a URI that goes 'offline' every 3 to 4 days? A <br>> simple warm boot command or astres.sh will bring it back on line as well <br>> as unplugging the URI and plugging back in.<br>> <br>> There is no indication that it's not working to the online user.
