<FONT FACE="Arial"><SPAN STYLE='font-size:12pt'>We have an asterisk node that runs three USB URI devices and it works well. Getting there was an education. We found that we needed to spread out our USB devices amongst as many Bus’ as you can. Loading down a single bus will create breaks in the sound. If you want things to work better add USB 2.0 sound cards to increase the USB bus count. Use the lsusb command to see how things are placed. Below is our layout.<BR>
<BR>
As you found out, ACID is based on Centos 5.x which does not work with USB 3.0. <BR>
<BR>
We still use a blend of RLC-DSP404’s and Allstar. If you are making the move to a PC-Linux solution, I suggest investment in SSD, UPS for AC, and a remotely controlled AC/DC power switch to control the computer. <BR>
<BR>
Thinking along the lines of your BBB solution, you could probably do things with two PC-Linux servers.<BR>

</SPAN></FONT><BLOCKQUOTE><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>We’re looking at app_rpt for sites with up to eight radios, all currently controlled by a RLC-3. Our initial approach is to use a PC and try to run all eight radios off of it. For testing we’re using modified fobs running on USB 2.0 ports and when we try to use more than four, things break up, sound bad, etc. I’ve found that CentOS 5 that comes on the ACID disk doesn’t support USB 3.0, which we were thinking might offer more bandwidth and handle the added fobs.<BR>
<BR>
Has anyone used this PC based approach for 4+ nodes using USB fobs? Or could I get some suggestions as to how to approach the implementation of eight nodes without using fobs or the discontinued 4 port PC card? <BR>
<BR>
Or is it a viable solution to use a BBB for every radio and connect them all with Ethernet switches and treat each BBB like a separate server.<BR>
<BR>
Any ideas are appreciated<BR>
