I'm running a PC with usbradio.<br>
<br>
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.<br>
<br>
Unplugging the URI and plugging back in does reset it. When it's
not working, the green LED is steady.<br>
<br>
<br>
Thanks!<br>

What computer are you using? 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>
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">
