help please/offer advice

hey there guys!

i’m new to this forum so what’s up? anyway, i have a problem with my s4 mk1 and my mk1 novation launchpad,

i’m currently using a windows surface pro 3 (which only has one usb port) so i recently bought a non powered usb hub to accommodate both devices to work with my traktor, however i can plug in the launchpad and it works but i can’t run the s4 off the hub and traktor doesn’t recognise my s4 until i run it off the main single usb on my laptop, how can i fix this issue?
many thanks
ollie

You’ll want to get the S4’s power supply like Patch recommends, this will also get better headphone volume and LED brightness out of the S4.
