I have a VOXL2, with a MicroHard modem breakout board attached. I also have a USB hub that is independently powered and daisy chained to the MicorHard breakout USB port so that my VOXL has more USB connections available.
Observing dmesg, I randomly see that all of my USB devices get disconnected, one by one, followed by a reset of the MicroHard USB chip. I have checked for loose cables, and also can not force this issue to occur by inducing vibrations.
Is anyone aware of a bug or common issue that could cause the VOXL2 to force reset down stream USB devices?
