I noticed, the endpoint attributes are slightly different that the FTU. Could this be an issue? I'm also guessing that the mixer lacking channels is probably an issue. I wonder if the some the FTU mixer "workarounds" may fit. On 4/21/2012 5:19 AM, Grant Diffey wrote: >>> (channels = 2, ifnum = 2). >> >> Why do you use channels=2.
