The otg port on the bananapi does not have a proper host controller,
instead it uses the musb app gadget controller in host emulation mode,
this is known to not work with some devices. You really should use one
of the normal usb a ports on the bananapi, which are connected to a proper
usb host controller.

Here is little more debug info:

I am trying to connect a DAC via OTG port in host mode to Banana PI. Of
course I am using powered HUB and some devices works fine. Among them one
DAC (M2Tech Hiface).
But I have a problem with another one (Oppo DAC 2.0). It refuses to work
with (3.4.109 / 4.3.0) while* it works on a normal USB port*.
Is there any hope / hint?
Igor
