[arm-allstar] PI-2 Physical USB port numbering order?

[Ken Page]

Hi Doug,

Yes I know about the LSUSB command.

However what I'm after is can you tell me the physical location numbering of the USB ports on a R-PI2 when looking at the physical connectors?

Or do they come up randomly as they are detected?

And so even though there are 4x USB ports are you saying trying to run more then 2x URI's is a waste of time because the PI-2's don't have the horse power to handle it?

If so, how about 2x URI's + a conference room for LL dial-in's + routing some internal calls from ATA's on our LAN? Too much for the poor little thing?

Or will I need more PI's to do this as separate devices?

On a side note, I'd like to use another PI-2 to stream and record Live Free to Air TV within our LAN to PC's on our network.
Anyone know or recommend any Linux Image options there?


Thanks,
Ken - vk4akp

Ken,

  Congrats on getting your Pi2 up and running. There is a lot of information on the hamvoip.org web page especially in the how-to section.

If you want to see what devices are connected and where on the USB chain do -

[root at alarmpi ~]# lsusb

Bus 001 Device 011: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter
Bus 001 Device 010: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter
Bus 001 Device 009: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. SMC9514 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

In this case I have two USB audio FOBS connected. That is about max for the RPi2. You can plug in other things as you mentioned on the other ports.

There is a section in the setup on how to connect two radio ports. It is important to follow that and also mark the ports once you are done as the devices need to be plugged into the ports that were configured and remain there.
The setup only configures the first node. The second node remains port 1999 and can be configured to your node manually using nano as per the docs.

We are here to help so if you have a problem don't hesitate to ask.
