How can I run these and some old U1's at the same time?

I need to be able to set the u1 clock's and the compaq ones.

I was running this: ./bfgminer -S antminer:all --set-device antminer:clock=x0981 -o stratum+tcp://peercoin.ecoining.com:3336/#skipcbcheck -u blackbird.1 -p 12345 --failover-only --failover-only -o stratum+tcp://us.d7.lt:3333 -u blackbird.1 -p 12345

But it looks up the compaq's as well. Shouldn't the -S antminer:all command tell it to only pick up the antminers?

I was hoping I could run two instances, with each one looking like this:

./bfgminer -S antminer:all --set-device antminer:clock=x0981 -o stratum+tcp://peercoin.ecoining.com:3336/#skipcbcheck -u blackbird.1 -p 12345 --failover-only --failover-only -o stratum+tcp://us.d7.lt:3333 -u blackbird.1 -p 12345

./bfgminer -S compaq:all --set-device compac:clock=x0b83 -o stratum+tcp://peercoin.ecoining.com:3336/#skipcbcheck -u blackbird.2 -p 12345 --failover-only --failover-only -o stratum+tcp://us.d7.lt:3333 -u blackbird.2 -p 12345

That doesn't work, however. It doesn't detect the compaq devices in the compaq instance.
