PBX Conference still choppy after adding VoiceTime USB Sync

I just acquired a VoiceTime USB Sync device to improve timing and fix choppy issues with my conference center.  I'm on Elastix 1.3-2 Asterisk 2.6.0.0, zaptel-1.4.12.1 with no analog hardware.


Following the install wiki - http://wiki.sangoma.com/sangoma-wanpipe-voicetime#install I installed the wanpip voicetime driver  ver 1.0.9.  Since I already had zaptel on the system I bypassed that portion of the instructions.  I've rebooted the server, and everything I check in the debugging sections is in the affirmative, except the zttest.

My latest test:

and it is still choppy, as if the usb isn't there.

lsusb shows the USB on a port:
Bus 002 Device 003: ID 10c4:8460 Cygnal Integrated Products, Inc.

dmesg |grep USB turns up:
