Bitcoin Utopia 2 ASICS 1 WU?

I've been trying to run two U2 antminers on the same WU. Until recently I had 3 antminers on the same powered hub but one was a u1 and well I just didn't want to try. I've since moved the u1 to another machine and have two u2s on this machine and I changed my app config to the following:

<app_config>
<app>
<name>C-cgminer</name>
</app>
<app_version>
<app_name>C-cgminer</app_name>
<plan_class>miner_asic</plan_class>
<avg_ncpus>.1</avg_ncpus>
<cmdline>–usb :2 --anu-freq 250</cmdline>
</app_version>
</app_config>

Currently it runs 2 WUs independently, my cc_config has asic count set to 2. i feel like I missing something other than "usb :2" to tell the machine to run the two on the same WU. Any input would be appreciated.

Stupid question: Did you try setting the asic count to 1 in the cc_config file? You'll only run 1 WU, but I don't know if it would be spread across both...
