USB OTG - Huawei P20 Pro Questions & Answers

According to this page, the P20 pro officially supports USB OTG. But when I plug this USB key to the phone with the official cable and a simple female - female adapter, nothing happens.
Does it only work with USB type C keys like this one?
If it is the case, I would really like to understand why.

I think you need a USB connector that supports OTG. Your USB 3.0 to USB C adapter that is.
I had a similar issue trying to connect a micro USB infrared camera to my Nexus 6P, had to get a specific OTG converter.

No special usb connector needed, works direct and without problems.

HTC Advantage 4 - 1 Cable, Not Working??

Hiya,
I just got my cable from expansys, the vga and s-video out is working fine, but i haven't got any thing usb to work yet. I've tried flash Drives and a card reader, just no response, no light or any thing... is there a trick to it or is it not very compatable or is there a chance mine is faulty?
cheers
My guess is that although it is a Host, it does not supply any power, I say this because the battery is only 3.7 V DC and USB devices are 5 V DC, this means that there is not enough Volts in the advantage to power a USB device to start with, never mind powering a USB device and an Advantage at the same time.
You will probably need to plug it into a USB hub that supplies it's own power, like this one

I had the same problem but it was because the TV out was still on. Once I turned this off in the settings menu it worked fine.
I too had no trouble hooking up a flash drive. No other peripherals were attached to the cable. Alas, no go on a hard-drive MP3 player, but trying a powered hub is a good idea.
Have you tried connecting your USB device, and then soft resetting?
Works for me.
I have no detection of USB devices by my Advantage.
I tried with and withour Soft Reset before and after the cable connection, before and after the cable and flash drive connection, with or without the VGA or Video Output disabled or enabled, but my Advantage does not recognize any USB device (I tried with 2 flash drive, a keyborad and an optical mouse. Nothing to do. These devices do not work with my Advantage).
It seems that the relative drivers are missing.
Someone has a sure fix or solution to this problem ??
Thanks
Battery Powered USB Hub...
This device should work well with the x7500/Advantage. It doesn't require you to carry around a bulky power plug. It runs off of 4 AAA batteries and provides power for up to 4 USB devices. Since the x7500/Advantage has limited power and can't power external drives itself, this is a nice addition and cheap. Hope someone finds it useful.

I have the Dopod U1000. I have connected a thumb drive and a USB mouse without issue. The mouse is useless as far as I can tell as there is no pointer though the buttons work.
I have no problems with a T-Mobile Ameo and a 1Gb Corsair USB Flashdrive - don't even need a soft reset. It's listed as 'Hard Disk' on the Ameo.
Question though: can I just unplug it when done? I'm used to 'safely removing hardware' on the PC, and it just feels wrong unplugging it from the Ameo, but I can't see any similar 'safely remove' method.
Hi.
It depends of the usb device. My 1GB pen drive is recognized but my 4GB isnt recognized (my 160 GB isnt). So I suppose If the usb device isnt powered then only "very low powered" devices are recognized...
If I connect my 160 GB and I plug it to AC then It is recognized correctly...
Does mini usb-usb host cable exist? Where to buy it?
THX!

Search the forum for the Modaco Mouse driver. It has a mouse pointer and works flawlessly with a USB Mouse!

Hi,
I have the HTC 4 in 1 cable for the T-Mobile Ameo (HTC Advantage 7500) and the ability to access a USB thumbdrive or stick appears to depend on the device.
The following devices worked without a hitch:
- Kingston DataTraveler 1GB
- Q motion 1 GB
- SanDisk MobileMate SD+ (This a SD card reader in a USB stick format, very handy to copy data from a SD/miniSD/microSD card to your 7500 without going through Activesync)
Another noname USB stick that I had did not work.
So the trick is to find a low powered USB stick.
Cheers,
Tim
Please can someone give me some exaples about how could I use
Video/S-Video/ option in 4 in 1 cable, considering that I can image how to properly use VGA out and USB host?
THX so much!
Hi,
before I buy it, could it work?
USB 2.0 (compatible 1.x)
Adapter USB from Type A (female) to mini USB 5pin (male)
THX so much!

Yes, that should work for you. I'm sure it's not more than $5.00 USD. ;-)

Are you hoping to connect USB accessories to your Athena with this?
If so, it will not work.
Only the 4 in 1 Host cable connected to the ext USB socket will do that.
This adaptor will only connect to the Sync & Charge socket, and will not provide USB Host capabilities.

So it will not provide me host function...?
Than the HTC cable should have something like a "chip" in it to provide host, is it right?
Yes, the USB Host chip must be either in the addon cable, or linked to the extUSB socket in the Athena. But definitely not the sync & charge socket.

OTA ICS: USB Disk mount?

when looking at the storage control panel, it lists internal, sdcard-ext, and then "/mnt/usbdisk_1.1.1" and says "insert an [sic] USB disk for mounting".
so if i were to come up with some sort of adapter, could i plug a thumb drive into my phone's micro usb port to move files between the phone and the thumb drive? i can think of plenty of times that would be useful!
Tried. OTG cable works with Samsung galaxy S2 devices (Skyrocket using either SKY ICS or rooted OTA) but haven't got it to work on our Droids...(Bionic ICS leak, RAZR ICS OTA, Droid 4 ICS OTA...all rooted).
But if someone can prove me wrong I'd be happy to "eat my words" ...
Be strong and very Koragus, my ninja...
OTG works, BUT only in a very cumbersome way, since external power is needed.
A powered USB hub does not suffice, since it only powers the slave devices, not the host (= phone). The phone must be in charge-mode, which requires a Y-cable.
You need:
- an OTG adapter
- a USB hub with mini-USB in
- a USB Y cable with 2 normal USB plugs and one mini-USB out
Then
1. Connect the OTG adapter to your phone's micro-USB input
2. Connect the 'middle' USB plug of the USB Y cable into the OTG adapter
3. Connect the 'outer' USB plug of the USB Y cable to a charger (can be a portable battery as well)
4. Connect the mini-USB plug of the USB Y cable to the hub output
5. Connect any device you want to use to the USB hub
It looks like this (found this picture for Razr):
http://www.flickr.com/photos/teppan_hakushaku/6817735705/
Edit: I verified it for Droid 4 last week, but didn't take my own picture yet. Works with ICS .215 leak, no 3rd party apps (like 'StickMount') seem to be needed.
Edit2: According to some other posts in this forums (search for 'OTG') it will only work for FAT32 formatted drives. Didn't check this in detail but my drive was already FAT32. Also I found it did not work for my cheap wireless keyboard's USB dongle, but connecting a wired keyboard worked fine.
...reminded again why I love this community...
...no possible links to a purchase of this "y" cable?
Be strong and very Koragus, my ninja...
Glad I could help!
They come with some portable harddisks, so that's where I got mine. Not sure about the linking policy on XDA, please remove if not allowed. Here's an example:

Otg usb3.0 hd

I just bought a hard drive to connect to my nexus 10, but like an idiot, I didn't realize it was a USB 3.0 drive. I have an OTG cable. I am wondering if there is a way for me to externally power the hard drive. It has a single USB 3.0 female plug. Hopefully the attached picture can explain better what it is that I want to do.
I wonder if this would work
http://www.amazon.com/HDE®-Male-USB-Micro-B-Cable/dp/B006C0S2JS
I could connect the USB 3.0 connector (right-most) to the HD, the blue Type-A connector (left-most) to the OTG cable and the other USB (center) to a USB hub or power supply. Anyone have any experience with this type of thing?

OnePlus 3T out video to monitor via hdmi

I want to connect a 27 inch monitor or projector.
From the official support says (ticket #770598, from Sky) that phone 3T supports out video via HDMI
I understand that you wanted to know if OnePlus 3T supporte USB to HDMI. I can provide you with the information that you needed.
I would like to inform you that OnePlus 3T supports HDMI as long as it is connected to the OTG cable/ converter.

Phone have usb type c version 2.
My questions:
1. This phone is really support hdmi alt mode? I don't see the image HDMI (or DisplayPort or Thunderbolt) alternat mode on the box.
2. If (1) is true. Any cable good for me? Ex. usb type c multiport adapter from apple store or necessarily with OTG?
3. How big is the latency video of through miracast (ex. ezcast)? If connect mouse and watch on cursor movement.
I tried this yesterday with a USB C to Hdmi adapter I got off Amazon and I had no luck connecting to the monitor.

Thans for the reply
I think they sold me a dud
Phone not supports MHL and other alt. mode
II wonder if a driver could be put into a ROM to support it via USB OTG since it doesn't support MHL?
I have an old external sound card, a Creative Xmod, that works perfectly with my roommates USB C, OTG adaptor.

I think because it is not implemented in hardware in the phone
If I'm correct Display Port alternate output requires USB Type-C 3.1 since the phone supports only 2.0 it shouldn't work. However not many phones utilise this feature even Google Pixel doesn't use this mode
Video out works fine on the 3T but only with Displaylink adapters. (So far anyway)
I have one and can confirm it definitely works either via HDMI or HDMI to DVI (I've tried both)
I used this one: https://www.amazon.com/gp/product/B01N40RQV4/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
but any displaylink adapter or dock will work. (Make sure it very specifically says dispaylink, check the displaylink website if you aren't sure)
The only note is that displaylink says the Ethernet ports on the docks do not work with android.
(I suspect they might work on devices that support a regular Ethernet adapter though, I haven't been able to get a normal Ethernet adapter working on my oneplus 3t though for what that's worth.)
you will also need the displaylink app from the playstore though it does not have to be running.
if any of you have experience using an external Audio DAC with USB Audioplayer pro the process is very similar.
Once you plug the monitor in, a pop up will ask if you want to let the displaylink app control the adapter and if you hit "ok" it does the rest automatically.
Does the phone charge while connected to the DisplayLink adapter?
Just try with Chromecast or anything else with Mirascreen option
Does it work with Anker Premium USB-C Mini-Dock
Hi there everybody:
Have anyone tried to connect a dock like the Anker Premium USB-C Mini-Dock, Does OP3T work for charge and to view the USB ports of the dock? May be HDMI and Ethernet doesn't work but for me the matter is the chargue and the USB ports to connect an external DAC, a microsd and a pendrive. Regards.

The 10 Ultra has no output on usb to hdmi connector. I tried it as I wondered after coming from a p40proplus which had a desk top mode. I imagine the 11 will be the same as it promotes the desktop app to share it's display like the 10.
You mean in wireless mode?
Yes,USB 2.0
It is still USB 2.0
Such a shame. Imagine transferring 500 GB of data with 30 MB/s rate.
usb 2.0, hahahha~It doesn't deserve to be called “安卓之光”
It's really disgraceful to use the best CPU money can buy , best ram, fastest ufs storage , best display , best charger and then go cheap on something like a USB 2.0 port.....
Someone who thought this was a good idea should be fired....
Yeah, i really don't understand why they put an usb 2.0 port. For a 2021 premium phone it's a nonsense.

I have not received my Mi 11 Ultra yet, but I believe it should work when using a Displaylink USB to HDMI Adapter and installing the Displaylink App on the phone. With USB 2.0 it should work fine for resolutions up to Full HD.
The USB Type-C Specification states that it must support at least the following standards, otherwise a Type-C connector cannot be used:
• USB 2.0 Specification
• USB 3.1 Specification
• USB Power Delivery Specification, Revision 2.0 (3.0)
• USB Billboard Device Class Specification, Revision 1.2
• USB Battery Charging Specification, Revision 1.2

I had to power the USB C adapter then I plugged the Displaylink adapter to the USB C adapter.
It would not work without power.

I use this
CableCreation USB HDMI Adapter(DisplayLink Chip), USB 3.0 to HDMI External Display Graphics Adapter Compatible with Windows 10/8.1/8/7, White https://www.amazon.com/dp/B07DX33L5...abc_D4RSEZX9P70E6V3KSFR4?_encoding=UTF8&psc=1
You need any USB C hub with a USB B A 3.0 hub and PD pass through.
Something like this
USB C Hub - TISOFU USB C Adapter with 4K HDMI USB3.0 SD/TF Card Reader 100W PD, 7 in 1 Type C Adapter Compatible for MacBook Pro, USB C Laptops Nintendo, Type C Devices(Gray) https://www.amazon.com/dp/B099WTZGM...abc_R2F1P2X1274TN188EYAV?_encoding=UTF8&psc=1
Then you need to give the hub power and then plug the displaylink adapter and the HDMI from displaylink to your video out device
Open the displaylink app on your phone and then plug your phone in.
Give it a few seconds if it didn't detect replug the USB C hub.
It's a messy dangle of wires but it works
