How to enable ACA (OTG + charging) on Oneplus5 Ubuntu Touch 20.04
-
Hi, I just successfully flashed my old OnePlus 5 with Ubuntu 20.04 using UBPorts installer.
But I can't make my phone to be charged while reading a USB drive. I tried using Anker powered hub, but the phone can either charge or read external drive, but cannot do both at the same time.
How should I enable this ACA (Accesory Charging Adaptor) mode?
Thank you. -
@albert-0 What happens when you charge while a flash drive is mounted? It gets unmounted?
I don't usually use flash drives but I've tried external display and/or mouse/keyboard and charging usually just works even on old devices like the Nexus 5.

I tried a few different steps:- I plug the power & external drive to the hub, then plug in the hub to phone (only power works)
- Only plug ext drive to hub, hub to phone. At this point the ext drive works, but later I plug in the power to the hub, it doesn't charge and just continue reading the ext drive.
- Only plug the power to hub, hub to phone. The charging works fine. But after I plug in ext drive, it just ignores the drive, and continue charging only.
Basically whatever it does first will stay and ignore the rest. I tried with LAN cable too since the anker hub also has the socket for Ethernet port. It behaves the same as the ext drive.
I suspect that the hub was broken, but nope, it works on my macbook and Samsung Galaxy phone.

@albert-0 I'm gonna test it on my devices but I have no OnePlus device. I've heard OTG limitations in OnePlus but let's see

@kugiigi thanks a bunch
Btw, what other devices that you can confirm can do that? I may just try and find second hand phones. -
@albert-0 I tried it on my Fxtec Pro1-X and Fairphone 4. They seem to work fine. I don't have a FAT32 drive though so I just used the external storage app to test if the drive is read.

@kugiigi thankyou for your kind help. I think I've figured out why after reading so much, I found out that not all Android devices support charging and OTG at the same time, some mentioned the value of resistor on certain pins.

Anyway, thank you again for your help Kugiigi -
@albert-0 On my Vollaphone charging and using mouse/keyboard at the same time via a USB-hub is also working.
