Hello everyone,
I'm midi communication problem between the FCB1010 and the iPad mini retina when I turn simultaneously the GR55. in USB hub are the two midi interfaces for both pedals and the UCA222 to GR55 audio shipment to the iPad via the lightning adapter. Interestingly, the interfaces work well separately, but when linked together FCB1010 no longer responds.
The USB hub is not powered. suspect of a power outage for 3 connections or some internal midi conflict. what do you think?
Thanks

Elantric

Use a powered USB Hub


ok, but I have doubts about the voltage and amperage to avoid damaging the equipment. I have at home a powered source of 4.5V and 600mA and other 5V and 350mA. Which one is most appropriate in this case?

You will need an official Powered USB Hub, most come with a 5VDC @2.5Amp supply

Ok, but the problem is that I am a small town in Brazil and the best USB hub that I found here, has an input for external power supply, so the question. I have several power supply stored in the drawers of other equipment and old cell phones, perhaps some work. Now found a 5,7V and Nokia 800mA.

USB is very specific
Must use a power supply with exactly

+5VDC and at least 1Amp (1000mA)  current rating
