You could try using a powered hub, or ideally a USB3 hub.  These offer
more power per port, which generally stabilises USB issues.

I'd welcome knowing about how to get[1] an external, externally powered
USB3/2 hub that works reliably with my ARMX6.

FWIW I've tried two USB3 hubs from CPC and they both give problems like
'back powering' the ARMX6 and misbehaving with my Linux boxes, so I avoid
using them. As is, I do use a more reliable, but old and slow, USB2 design,
but would welcome something better/faster.

The most reliable way to avoid back-powering would be to use a lead with 
the power lead cut/missing. I don't know whether these can be bopught, or 
would need to be "adapted".
