OTG USB Hub not recognizing mouse + keyboard.

[SpyFi]

Hello, I purchased a Dodocool 3 USB 3.0 + HDMI + External Power hub for my OnePlus 7 Pro. The adapter works fine on my Note 9. However, I can only get HDMI to work with my 1P7P. I have OTG Enabled. Any advice? Would really like to use the hub / monitor / keyboard and mouse. One I use a standalone type c to a OTG adapter keyboard and mouse works, just not with the hub.

Thank you in advance!

USB storage is detected on USB 3.0 ports just not the mouse and kb.

I have the same issue and I opened some threads around the web looking for other feedbacks.

The problem seems to be common on hubs that deliver video out. I tried using the original OTG cable paired with a simple USB3.0 4 ports hub and all the devices are properly recognized. Instead, complex hubs are recognized as a "storage" device, no matter what you attach to them (but storage + HDMI works on several hubs).

I posted a similar question on Reddit. No answers yet, I basically want to know if Dex style hubs work with op7p. I currently use my old v20 with HDMI USB mouse and keyboard with power delivery, but it doesn't work with my v30 even tho USB to HDMI works. I want to buy this phone, but don't want to make the same mistake twice. I like using moonlight to stream my PC for gaming.

Dang, yea - I wonder if it is an issue with usb 3.0? It detects drives attached and HDMI just cannot talk to kb or mouse. I am going to keep poking around the system.

I wonder if it is a kernel level issue?

 

[SpyFi]

I fixed it! Flash this kernel! https://forum.xda-developers.com/on.../kernel-kirisakura-1-0-0-op7-pro-aka-t3933916

So just to clarify, HDMI, USB keyboard/mouse, SD scard, and power delivery all work together?

Yep 100% after flashing the kernel.

Can confirm, same here! It's just that kernel though, other kernels don't seem to work.

Which kernels have you tried? It would be great if we could make a list of working ones.

I'm wonder if this will fix the issue I'm having with my PS4 controller via otg? It doesn't work at all except for in Steam link app. Sorry for hijacking the thread.

Probably it has to do with it, I'm having issues with the Xbox 360 wireless receiver here. :/

Have you tried that kernel mentioned above?

Kigiasakura is the only one that worked for me.

Not yet. I'm thinking of giving it a go, but I've never had any custom kernels.

I'd back up via Twrp then flash the kernel.

Is there a Kernel that would also work for the OP6T?

 

[HamderTipo]

Just installed twrp, rooted my new and fully updated OP7 Pro and then flashed the kernel but the result is the same.
USB-c to USB works
USB-c to hdmi works
USB-c to HDMI/USB/SDCARD/JACK/RJ45 - Only HDMI Works.

Anyone got any suggestions to where I might have gone wrong?

 

[TakuyaKimura]

Does anyone have another solution other than flashing the kernel ? i dont want to root my phone and i really need to use my device to connect hdmi+usb port+audio jack at the same time .

my huawei mate 20 just work fine . but oneplus 7 pro doesn't .
