Can't find device at setup while connected to ethernet cable

I was trying to set up 2 separate devices on my laptop for 2 sirrocos so I could play in diffent rooms. I don't know if the cds have a security setting not to allow, but now my laptop won't find the connected sirroco. It won't find either one and it won't find them on another laptop. I've tried to reset, but the reset light won't light. I've tried to update the driver and firmware, but when I get to the device config prompt or the firmware update prompt both computers say they don't detect any device. Any help would be great as I've got 4 hours in this already.

Update on 2 Sirocco status

Inexplicably, My laptops now pick up one of the Sirrocos, but not the other. Happy to have one back, but need a recommendation of how to set up the other without risk of losing the first again. As I mentioned in general forum I have 2 units and don't know if crossing the Cds can create a conflict upon setup.
