[App_rpt-users] toggling power on USB buss

[Jon Rorke]

In the past I have had this problem too. When this occurs, the green 
light is on the URI but not blinking. If you do a lsusb at the console 
it will report the device is detected and active.
But the node will not key up the radio when there is traffic. The only 
way to recover that I have found is to reboot the box. Also in this 
condition the node still receives audio and passes it along to any nodes 
connected. It just doesn't TX anymore.

I had one pc that this happened once or twice a week until the PC 
finally failed altogether. I replaced the PC with another make model and 
the problem went away for 3 years. Now it is acting up too.
One thing to note is we tried moving the URI to another port on the pc 
and that seemed to reduce the intervals between it dropping out. For now 
it doesn't happen too often now. Maybe once in 3 months so far.

But never seem to get it resolved.  In both cases the PC was a P4 3 gig 
box with 1 g ram so lats of power to do the job of a 2 node box.

Just my experience on this.
