A powered USB Hub is the answer. I have three ports on my main laptop. I usually connect my interface and main keyboard on the same two ports, then I use the 3rd port for my hub. It does not matter what order my my other keyboard, foot pedal, mouse etc are in on the hub. Just make sure it is “powered” as the laptop is limited on how much power it can distribute. The powered hub relieves the laptop drain. I’ve had no problems with it in 2 yrs. Again order does not matter in the hub. I have a 7 port hub. The 1st 4 ports (closest to power input) distribute power equally, the other 3 ports are reduced power.
