# Bitcoin rig setup, connecting a Butterfly Labs unit using USB

(Asked by: username_0 on 2013-12-30)

I'm currently running a rig with seven block erupters in a 10 connector powered USB hub. After taking the USB fan into account, I have an additional two USB ports available. The host is an old laptop.

I've just purchased a [Butterfly Labs](https://products.butterflylabs.com/) 30 Ghash/s unit. What is the best way to combine this into my rig?

Can I plug it into the USB port, even though the Butterfly Labs 30 Ghash/s unit is self-powered? Otherwise, should I connect the Butterfly Lab unit directly to a USB port on the laptop? Will there be any difference?

I'm mining with [CGMiner](https://en.bitcoin.it/wiki/CGMiner).
