Reply to new diy home-made controller

hello all,

i'm starting to work on my new diy home-made controller, i'll be using two gamepads and a exterior sound usb board for input and phones

i'll have 33 buttons and 8 faders, i'm believeing of installing led for each of the buttons/leds

now the trick question, i'll have a usb hub to connect everything, do you believe that the hub will have energy for all of those components?

and if the hub is powered?

should i loose that high number of leds?

thanking you in advance
fbonito

ps. sorry for my bad english...
