[App_rpt-users] USB Pointing problem- More info?

That brings up some questions I have about this- I have 2 interfaces on the Pi2 running Dougs image, sometimes when I reboot it, the two nodes both try to use the same interface even though they are configured in the tune files. Throws up errors in a continuous loop. When I restart asterisks from the command line it then works as it should and the two nodes are using their assigned interfaces. It's almost like the two interfaces are not fully initialized before asterisk starts on bootup. Now this is what lsusb shows:
Bus 001 Device 005: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter
Bus 001 Device 004: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter
When I used the tune menu to set the levels it wrote in the devices as follows:
For node 42051: devstr=1-1.4:1.0

For node 42078: devstr=1-1.5:1.0
Should I change that to 1-4 for node 42051, and 1-5 for node 42078? Andrew.

You may have a USB pointing problem between asterisk and Linux.

On boot up type "service asterisk stop" at the command prompt

Type lsusb at the command prompt. 

[root at Xxxxxx~]# lsusb
Bus 004 Device 004: ID 0d8c:013c C-Media Electronics, Inc. CM108 Audio Controller
Bus 004 Device 001: ID 0000:0000  
Bus 004 Device 002: ID 0d8c:013c C-Media Electronics, Inc. CM108 Audio Controller
Bus 001 Device 001: ID 0000:0000  
Bus 003 Device 001: ID 0000:0000  
Bus 002 Device 001: ID 0000:0000  
Bus 005 Device 001: ID 0000:0000  

Then make sure your tune files ( in /etc/asterisk) properly point to your USB device such as a URI in devstr=  (see below example)

[root at xxxxx asterisk]# cat usbradio_tune_usb<node#>.conf
[usb27178]
; name=usb<node#>
; devicenum=1
devstr=4-2    ; Bus 004 Device 002: ID 0d8c:013c C-Media Electronics, Inc. CM108 Audio Controller
rxmixerset=125
txmixaset=500
txmixbset=500
rxvoiceadj=1.820479
rxctcssadj=0.500000
txctcssadj=0
rxsquelchadj=825

Correct the tune file then

At the command prompt type: service asterisk start

Thanks,
Bob
