iPad Pro iPad pro 2018 12.9 inch cannot use OTG function (mouse, keyboard, monitor, earphones via TypeC port)

[iPadLover.v01]

I cannot connect these accessories to my iPad via TypeC port. They don't work.

Its charging function OK. I can connect to transfer data between iPad and my PC OK.​

​

Only OTG function does not work.​

The last time I used OTG function (external storage, mouse.... no problem) was 4 years ago.

​

Yesterday, I connected my earphones, external monitor, mouse, HDD.... none of them worked.​

​

All these accessories work normally with my other iPad Pro, iPad Air, Android phones, Laptop...​

​

I did factory reset already. The problem is still here.

​

Thank you very much.

1. what iPadOS version?
2. you probably did, but visually inspect the USB-C port on the iPad for any debris stuff sticking in there.
3. Check Settings > Face ID & Passcode > Accessories.
4. If and for which possible, check the peripherals connecting via a powered hub.

Thank you for your support.

1. Its version is 17.7.2
2. I did already. Checked and cleaned.

3. What should I do in this setting?

I see one setting related to Accessories. I tuned it on. The problem is still here.​

4. I tested on a powered hub already (this hub which can charge iPad and connect multiple accessories simultaneously. My iPad was in charging normally, but no accessory found). The problem is still here.

• Update to the latest iPadOS 17.7.9. After the update. Verify that the Accessory setting is indeed turned on. Shut the iPad down (no restart but shut down). Wait 'three Mississippis' , turn the iPad on.
• With the »Accessories« ON disconnect e.g. all peripherals. lock the screen. Unlock screen.
• Connect a peripheral, e.g., a monitor adapter without monitor connected (if available; the pure adaptor does not need a lot of power and should register with a visual indicator in the top right of your iPad).

If that does not work - you have access to a Mac?

Download and install Apple Configurator 2 . Among other features, it allows to check and overwrite set the Accessory setting mentioned before via a device profile, as well as access to the device logs.

1. Connect the iPad to the Mac and trust the computer
2. Start the Apple Configurator 2
3. Within the "All Devices" view double-click on the device attached to the Mac. An overview of the device is shown
4. Configure new settings in Restrictions payload editor <- explicitly allow Accessories
5. To better understand what is going on -> On the left hand menu bar click on "Console". The console of the device opens showing a live log

EDIT: in relation to the first steps checking with a pure monitor adaptor - if that does not work initially, please verify by disconnecting and reconnecting with the USB-C cable connector turned 180 degrees. I know it is USB-C but for diagnostic purposes trust me on this one 🤓

EDIT II: I just checked, the iPad (or iPhone for that matter) logs are actually directly from Apple Console after connecting the iDevice to a Mac (Applications/UtilitiesConsole).

I am upgrading my iPad OS to the latest OS. (18.6, because there is no option of 17.7.9).

I dont have MacOS devices. Is there any way to do on Windows 11.

--------
I just found that this iPad cannot use fast charging now.

I let its battery down to about 30%, I measured charging voltage/Current it shows only 5 voltage (the last time I measured charging voltage/current is 1 year ago. It showed 12 voltage).​

This ipad I use at home. Plug nearly 24/7.​

---

Update:

I upgraded to 18.6 version. Do tests as above guided, problem is still here.​

Sounds like the USB C port is failing

A USB C port can partly breakdown, cannot it?

I wonder why it can still charge, transfer data to PC.......

I only use it with Goodnotes for taking notes at home, plug 24/7. That is why I didn't know its problem before.​

​

Do you know what I can to to fix this? How much do I need to pay for to fix this?

Even I don't use this function much however it's so uncomfortable when knowing there is a problem with the iPad.​

USB-C port can partly breakdown. I once dropped my MacBook Air while it was connected to a charging cable. The port has no visiable damage, but it has lost USB 2.0 functionality. Devices using USB 3.0 and Thunderbolt are still detected, and the port can still charge. But all USB 2 flash drives, earphones, dongles and docks are no longer recognised.

Has your Macbook's typeC operated until now?

I wonder that after TypeC port is partly breakdowned, TypeC will be fully breakdown soon?​

​

Or will it make other functions/parts breakdown soon?​

​

Actually I don't know when was the TypeC become damaged.​

It's been the same for like two years. It works fine, only USB 2.0 functionality omitted. No other part of the laptop was affected.

I have tried to DIY repair the port but symptoms persist, so I think it's a motherboard damage.

Thank you.

I will ask some repair store for the cost of fixing this problem.

I just searched google, it shows USB C port of iPad is a module, not be soldered firmly on motherboard.​

What could also be happening is the battery slightly swelling, you won't necessarily see it from outside, but it could start messing with the inside. Swelling tends to happen when a device is plugged in 24/7, happened to me with an iPhone I was not using and kept plugged in all the time (also with a Windows tablet kept plugged in all the time, in that case the swelling broke the tablet). Let us now what the repair store tells you.
