USB OTG behaviour with multiple connections

Jan 11, 2019
I was just wondering about the behavior with USB OTG.
My pad is only able to make one connection via my external powered USB OTG hub; e.g. accessing the thumb drive or playing music with an external usb sound card or being charged. I have to reboot the pad every time i want to switch to one of these scenarios.
My Samsung S9 does all of this on the fly with no issue at all.

So my question is this related to the chipset, the ROM or the kernel of the Mi Pad 4 and can this be fixed?

Many thanks
