Add Dell Wyse 3040 as compatible device

Dell Wyse 3040 is odd - it has 6 ports advertised on USB2 and 7 ports on USB3,
and both USB2+USB3 do not advertise power switching support.
However, using -f it seems that power switching does work.
I assume it needs separate control for USB2+USB3 using -e as well.
