<FONT FACE="Arial"><SPAN STYLE='font-size:12pt'>The xipar release supports centos 6.x which supports usb 3.0 – there are pros and cons to Xipar.<BR>
<BR>
I understand that there are some people that have ACID running on centos 6.x – I am awaiting input from a colleague.<BR>
<BR>
I would go out and buy a bunch of usb 2.0 cards which add more buses.<BR>

Your setup looks exactly like the test rig I am using except I have four of the C-Media fobs. And yes, I discovered you need no more than two fobs per USB bus. With two busses available in the PC that limits it to four fobs. The goal is eight nodes per server.<BR>
<BR>
I’ve looked at USB 2.0 port cards and they seem to be going out of production. That is a concern for long term availability because we will be making the change over a period of several years. And a lot of them are PCI interface instead of the current PCIe used in newer motherboards.<BR>
<BR>
We’re hoping to make Asterisk Allstar the replacement for the RLC-3’s.<BR>
<BR>
I wonder if anybody has gotten Asterisk/app_rpt running on a distro that supports USB 3.0?<BR>

</SPAN></FONT><SPAN STYLE='font-size:12pt'><FONT FACE="Arial">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>
