[App_rpt-users] URI Problem

[Doug Crompton]

Steve,

  It sounds like it might be a SW issue in your PC. From what you say outside influences should reset the URI. Take a good look at your logs on the PC both system and Asterisk and see if you can determine anything.

    Doug.

      

      I'm running a PC with usbradio.

      

      This is something that just recently showed up. The system has
      been running fine at it's current location for over a year. The
      IBM PC that I'm using has a (heavy) metal chassis and I should be
      able to get a good ground on it back to the building's halo.

      

      Unplugging the URI and plugging back in does reset it. When it's
      not working, the green LED is steady.

      

      

      Thanks!

      Steve,

          

            What computer are you using? PC or Beagle Bone Black? etc. 
          Also usbradio or simpleusb?

          

          This is a common problem on the URI with external EMI and
          power spikes. 

          

          The problem can be fixed. You need to ground everything and
          eliminate EMI as much as possible. 

          

          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. 

          

          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 -

          

           http://www.crompton.com/hamradio/BeagleBoneBlackAllstar/simpleusb-howto.pdf

          

          See how to do the patch at the end of the pdf.

          

          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. 

          

          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.
