These devices are not able to communicate with each other. You will have to connect all of them to the USB to get full control.
Thanks for your your reply,
What is the best way to link 3 x PowerAjust2 USB's to Motherboard USB Connection ?
As I don't think I'll have enough free USB Connection on the Motherboard for No.2
(PA2= PowerAjust2 USB)
1. PA2 -> PA2 -> PA2 -> Motherboard (I would like)
2. PA2 ->Motherboard PA2 ->Motherboard PA2 ->Motherboard
Any further thoughts on PowerAjust2 connection would be helpful as I don't have English Manual. It's going be a bit of hit and miss thing.
Thanks
