USB hubs with BB Black?
Good morning. I seem to remember seeing posts recommending not using USB hubs. However, the BeagleBone Black only has one USB host connector. I'd like to use two URIx's with the BB Black. Any suggestions? 73 DE KC8RYW
Johnathan, I have successfully used the BBB with a hub (Belkin F4U040) and two DMK's. It works but it is pushing the envelope a bit both in using the hub and also two nodes. It might work for you and then again it might not. BBB's are cheap so a better idea might be to just run one BBB per node. You just need to setup another server, move you second node there and set the server iax address at allstarlink.org and the second BBB and you Internet router. This would also have the added redundancy of another independent server. Hopefully we will get the BBB GPIO setup for PTT/COS and then you can use any compatible usb sound FOB. Then the cost of each node will be on the order of $60 or so. 73 Doug WA3DSP http://www.crompton.com/hamradio Date: Mon, 12 May 2014 11:00:59 -0400 From: jonathan.weirmeir@gmail.com To: app_rpt-users@ohnosec.org Subject: [App_rpt-users] USB hubs with BB Black?

From what I have learned from Doug, others, and confirmed with my own experience is the fact that keeping processing overhead low improves success of using a single device formultiple nodes. Use simpleusb, or perhaps configure usbradio to not use PL DSP functions, will improve the ability to support multiple nodes, and have multiple nodes connected from the network at the same time. I use the Linux command "top" to show real time useage of memory and CPU %. Thanks, Bob kk6ecm Sent from iPad On May 12, 2014, at 8:55 AM, Doug Crompton <doug@crompton.com> wrote:
