powering multiple things off usb

[sean_scouser]

Hi quick question I am going to be using my surface i5 8gb ram 256gbhd to dj

Will the USB power the following devices as they are all powered just by USB
I've heard a few stories of the USB not giving certain devices enough power

I plan on using this hub first to get 3 USB ports

Into this I will be plugging this

And the music will be coming off a WD 2 Tb hard drive USB powered

Can any one see there being any problems with this

Cheers

I can already tell you it won't work.
I have the same hub and it can't work with an HD and a USB stick connected.
unless the dj deck is powered from somewhere else

So you need more Power. either a connection to an outlet on the grid or an alternate source such as a battery pack off the grid.

Maybe I could buy a SD card save all music to that then just run the dj controller from the USB maybe , wanted to use the HD to keep space free on my surface

An SD Card reader and an external HD work for me no problem.

I you get a USB 3.0 powered hub with an auxiliary 5v power adapter port, it might be sufficient, like this one:

You would also need a high current 5V power adapter.
