Connecting via USB Hub

Unread post by Mano » Wed Feb 06, 2019 7:50 pm

Hi,

I want to connect the MODX7 via USB for midi and maybe also for audio.
Due to fact that i extending my gear i need also to extend the number USB ports.

I have a powered USB 3.0 hub that have charging ports BC1.2 ... means that the output of these ports have a current output of 1.5A instead of the standard 0.9A

I was wondering if that will work and especially not damage the USB output port on the MODX


Kind regards,

Kind regards,
I tried via a hub and it was a bit unstable. Consider using a direct USB-connection as you run midi & audio through the USB-cable. Good luck!

Hi

Hub power draw limits should not come into it as you are not trying to power the MODX (it has its own PSU :) )

USB2/USB3 may be an issue depending on drivers/software. USB3 is meant to be backwards compatible, but I have had problems when trying to plug certain USB2 devices into a USB3 port. For example, MIDI data transfer with my MOTU MIDI Express 128 and external devices is terrible with lots of missing/hung notes in a USB3 port. Put it in a USB2 port and all is fine. I've also had trouble with a Focusrite Diamond interface when it is in a USB3 port.

I also have my Line6 Helix which will work with USB on a 5M lead, but not a 6M lead. All other devices I have are fine on a 6M lead.

All you can do is try it and see.

BTW: Most Audio devices are USB 2 as there is no audio bandwidth advantage in moving to USB3 (according to Focusrite anyway).

FWIW Derek, USB 3 only offers greater bandwidth, not speed. It runs at the same speed as USB2. Probably why there is not a surfeit of USB3 devices...most folks (and companies - apart from those that HAVE to be at the bleeding edge!) would not see the need.

That was my point :) Whilst USB 3 ha greater bandwidth, to take Focusright’s example, if you dropping a tennis ball down a pipe (where the tennis ball diameter is the size of your audio bandwidth) then dropping it down a 2M diameter pipe (USB3) will not make it fall any faster than it will in a 1M (USB2) diameter pipe.
