[Solved] DIY usb otg cable not working, where did I go wrong?

Hello.
I decided to try and make a DIY OTG usb cable for my atrix, followed one of the many guides on the web.
How ever, Nothing seem to happen when I plug something to the phone.
I tried keyboards, mice, pen tablets, thumb drives, but nothing happens.
Also when I connect the phone to my laptop with the same cable, nothing happens either. (From reading around I think that should be expected)
Using another cable the laptop recognize the phone and all is well so I didn't fry the port.
Something else that might be worth mentioning, I use a male micro usb to male regular usb and a converter to female at the end of that one.
I tried it with both latest CM7 nightly and Jokers 0.6.9.1 CM9, both on their stock kernels.
So am I forgetting / missing something or should I take apart the cable again and check what's wrong?
Edit:
Toke apart the cable, removed the connection between pin4 and pin5 and the cable worked as a normal cable again.
Can't think of a reason why this isn't working.

normal OTG cables don't work with atrix,
I have read somewhere that you need to power the otg cable with external power source, you can mod a powered usb hub for example

Thank you.
I don't have a powered hub, nor a regular hub...
So I'll try to make a usb y cable that will power the mouse/keyboard and see if that will work.
Edit:
That did the trick.
Made a Y cable that connects the data between the phone (with OTG cable between) and device and an extension that connects both to power only (currently from laptop usb).
At first it didn't work at all but after a few tries it started to charge the phone, allowed me to connect a DOK and a mouse.
However didn't want to work for a 250HDD or a pen tablet.
I ordered a usb hub and hopefully it will allow me to connect several devices at once.
Thanks again.

I've messed around with this quite a bit. Unfortunately, it seems Faux kernels don't work great with a variety of devices, but work fine for mouse/keyboard. Don't even work very well for USB flash drives and such. I don't even know where to go to report such issues.
This also means on Joker's CM9 it doesn't work great even if it should. Don't forget that CM9 port is still using a Froyo (!) kernel.
It's honestly not even worth building your own cable. You can get hubs that work for this for $5 such as this one:
http://www.dealextreme.com/p/cable-style-dual-power-1000ma-usb-2-0-4-port-hub-13526
Which is the one I currently have.

I'm currently using latest CM7 with the stock kernel and have no issues with USB flash drives.
It usually brings a notification of "preparing SD card" and mounts it under /mnt/usbdisk_1.0
I tried making 4 partitions on a flash drive, EXT2, EXT4 , FAT32 and NTFS .
Thought it only mounted one of them on /mnt/usbdisk_1.0 , it was easy to mount the others /dev/block/sda<1,2,3,4> onto /mnt/usbdisk_1.<1,2,3,4> thus having simultaneous access to all 4 partitions.
How ever the NTFS one only had read permissions since android and NTFS don't go together too well.
The hub you linked to is just a hub, I needed an OTG cable and ordered a 0.99$ usb hub that I will modify for power. so pretty much all set now.
As to reporting such issues, you could ask on the forums if other people have the same issues and how they get around them.

I got these:
http://www.dealextreme.com/p/micro-usb-on-the-go-host-otg-adapter-pair-50774
I tried all sorts of devices, not least of which was a 360 controller. The kernels are very spotty at recognizing new devices being attached.
this is on CM9 of course
I haven't tried to replicate that on CM7 because, frankly, CM7 isn't supposed to support 360 controllers.
The hub I linked is very convenient. It already has a USB power lead as well as a lead for the OTG adapter.

Anyone else not seeing OTG USB Devices?

I have no luck getting devices to show or mount within Stock B27.
Flash Drive LEDs will blink upon booting up but then nothing after the phone is fully booted.
We know that OTG works fine on the Axon 7.
I know my hardware/adapter is mounting USB devices and works fine within TWRP.
I'm on Stock B27 by DrakenFX
Rooted
Unlocked Bootloader
Write Protection Disabled
Am I all alone? Any tips?

What devices are you trying to connect to your phone?
I had some issues at first, but realized I had to wait a bit longer for the phone to analyze the USB sticks or external 2.5in USB drives or external 3.5in USB drives.
When I plugged one in, it would show the little OTG symbol for something is connected, but the phone would be thinking for awhile before it would actually show up as a drive.

Have you tried a different rom? See if it's just a stock issue?

I haven't tried any other ROMs yet. I prefer to stay stock because aside from the OTG it works great and it's my daily driver. I may update to Nougat after a week or so. Kinda letting the update dust settle.

I tried several devices, Flash Drives, Portable HDDs, SD Card readers, etc.
I've also tried plugging my 1GB flash drive in and restarting device.... waiting.... and no luck.
I'm under the impression it's something within the OS just not enabled/

I have the svae problem on Chinese device with European B09 rom.
Tried to connect through the adapter that comes included, and no response.

Do you get the little OTG symbol that says something is connected when you plug anything to it?
I also had a problem once, which turned out to be a faulty adapter.

I've tried three different adapters (including the one that comes with the A7). I see the flash drives LEDs blink upon boot up but not after phone is fully powered up.
I was getting the contents on flash drives on Twrp but now I can't get that. Not sure what I've done differently, but I'll keep digging.

You will need a USB-C to USB-A 3.0 Adapter to get it work, devices won't work attached to a normal USB-C to Micro USB Adapter. Neither with the adapter comes with the phone nor with an aftermarket (56K resistor) adapter.

This is what DrakenFX recommends and works for him. This is also what I am using. It's definitely a software bottleneck somewhere in my case at least.

USB-C hub not working

Hello fellow OnePlus 5 owners,
One of the features I was looking forward to the most on my new phone is USB-C, since I always hated that to use any USB device on my previous phone I had to drain my battery. I purchased the Ableconn USBC-4APD USB-C hub from Amazon with pass-through power but I am having problems.
When I try to connect the hub, the phone only recognizes power and shows it's charging less than one in a dozen times, and if I then try to connect any USB device (USB flash drive, keyboard) the LED's on the peripheral just flash once and nothing else happens.
I have tried the same flash drive and keyboard with a regular OTG cable and they work fine. I had a co-worker with a Pixel phone try the hub and it passed through power every time (I did not have a flash drive along to test), it also works as a hub on my laptop (did not try passing through power on that).
My question is, has anyone else tried a USB-C hub, and did it work? Is there something wrong with the OnePlus 5 (hardware/software) in general or something wrong with mine in particular, or is there something wrong with the hub?
I'd appreciate any help in figuring this out.

Is the USB-C cable from the OP5 to the hub an USB-C OTG cable? If not, I suspect that is your issue especially as you indicated the OP5 is recognizing the input to be at least a trickle charge. To my understanding any data access and it would be restricted to read only, requires an OTG cable and the OOS OTG setting to be toggled to on (Settings->Advanced->OTG storage). If you gave TWRP recovery installed you can also check the OTG capability by mounting OTG in the Mount menu as a test access alternative to within OOS.

You misunderstand, the USB-C hub does not require a cable to interface with the phone since it has a USB-C cable attached. I didn't indicate that it at least trickle charges, I said that it rarely recognizes getting charged, as in there is no charging indicator on my phone most of the time.
The OTG setting for storage was enabled, however based on you mentioning the switch I disabled it, and it actually detects power every time I plug the hub in to it with OTG storage set to off. This gives me hope that it's a software issue and can be fixed with either patches in the future, or more likely a custom ROM. I was planning on installing TWRP once Lineage OS is available, but I may try it sooner just to give this a try.
Thank you for the reply!

USB OTG a few things tested...

I've no idea if this will be of interest to any of you, especially those people who have yet to buy a 5t and are trying weigh up the pros and cons, but USB OTG is something I use all the time, so o it was one of the first things I tested when I got mine. So far I'm really pleased as everything I wanted to work does so. My last device, a Xiaomi Redmi Note 2, had very poor USB OTG implementation so this is great from my point of view. Maybe I'm behind the times and I had the last phone on the planet with that problem - if so, please delete this mods
First off, before you can use USB OTG, you need to head into settings, then advanced and check the OTG setting. It turns off after ten minutes so I created a link on my homepage using Nova launcher's activity widget menu.
*EDIT* As ny-hardcore has kindly pointed out below, you can also have an OTG quick toggle in notification area. This didn't work for me at first (or I was hitting the wrong thing), but now it does .
Tested and working:
USB card readers of various types, including micro USB readers, with the help of a USB C to Micro USB adapter (5 for £4 on eBay!). The only one that didn't work is a proprietary Samsung multi card reader that also has a full sized USB output and HDMI out too. This isn't very surprising of course, but they're to be avoided if you see one on eBay and assume it's a generic adapter.
80 GB iPod hard drive in a cheap enclosure bought via Amazon.
1 TB 2.5" Western Digital HDD - that's right, no USB hub required, just plug it straight in. The only other portable device I've owned could power it was a Samsung tablet.
2 mega pixel boroscope (using USB Camera app in Play Store) . So useful for finding slow water leaks under the floor or peering down a spark plug hole into a cylinder!!
Micro USB DVB TV dongle, via adapter.
Keyboards and mice via an OTG adapter, including a combination media keyboard with built in trackball mouse (this usually doesn't work on my phones for some reason). The UK keyboard layout is supported via settings so you can have a £ key - woohoo!
Other phones! I plugged my old phone in and discovered I could mount it in MTP mode and then browse its contents from the built in file explorer. For what it's worth, the Oneplus even charges the device that's connected to it.
When you need to eject the device there's a button that appears in the notification area. Sometimes this gets obscured, so swipe down a second time and the 'eject' will appear.
I haven't tried any game controllers yet, but so far the support has been so comprehensive I don't see why there would be a problem.
In the attached photo, the only thing that doesn't work is the black coloured multi purpose card reader on the far right.

In quick toggles you can add an otg switch.
You don't have to go in settings that way to enable otg.

Thanks, for some reason that just didn't work for me unless I went into settings/advanced as well. I can't recall which firmware I was on at the time and I haven't tried since The quick toggles are so far away for my little hands too (please Oneplus add a Xiaomi one handed mode - in fact, make it EXACTLY like Xiaomi devices).
LOL, typical, now it does work for me! I was probably pressing flight mode by mistake or something.

Just FYI, I've tried the following USB DACs with an OTG cable on my 5T and they appear to work:
- Fiio E17
- Meridian Explorer (v1)
- Audioquest Dragonfly (v1)

I just discovered my old Saitek X35/X36 throttle/joystick combo works too! That's a first for one of my Android devices too. Now I need something fun to test it with

Has anyone gotten USB sound cards to work *for recording*.
Like I have a Terratec Aureon USB MkII and would like to livestream my DJ sets to Facebook via the FB app, by hooking up the line-out on my decks to the line-in on a soundcard hooked up to my phone and have the streamed video use the soundcard instead of the internal mic which sounds rubbish.
Edit: Tried it, and yes it works, but you have to hook up to the mic port, not the line in, and this doesn't seem like a great idea. Any idea how to change it?
Edit2: Scratch that, phone rebooted itself during a longer test

That would be so cool if you can get it working. Wonder if it's the phone or the Terratec? I have NO experience in that area. Good luck! How much power does it draw? Would a powered USB hub in the mix help?

Hadn't thoughtof the power draw issue.
What I really need is a super cheap low power USB line-in of some sort. Though after further testing, FB live streaming is crap, with low quality audio and video in all the configurations I tried (Android app, Win10+Firefox, Win10 app) so I'm probably going to abandon this plan and try a different platform like Youtube or something.

Just cant get otg to work in my device, I am on OOS 4.7.5, rooted with SuperSu, tried a type c to micro USB adapter, also a type c to USB 3.0 adapter, I have enabled the otg option in advanced settings before plugging in the devices, I don't know whether its the phone or the adapter I use, what kind of adapter did you buy, is it a type c 3.1 to micro USB 2.0/ USB 3.0, could you provide me with a name of the adapter.

I have the following USB OTG adapters.
2 X micro USB to full sized USB (the long type with a two inch cable).
1 X mini micro USB adapter that is tiny.
1 X micro USB adapter (bigger than above)
1 X USB C OTG adapter with micro SD card reader built in.
All of the above work. In the case of the micro USB OTG adapters, I'm using a USB C to Micro USB adapter (they're tiny, about 2 CM long).
In short, every USB OTG adapter I've put in it works. All are unbranded, generic adapters that I've bought from Amazon or eBay. I've never had to do anything more than enable OTG in settings.
Could it be something to do with the ROM you're using?
In the attached photo, the ones with a yellow Mark are micro USB OTG adapters. The one with a red mark is a USB C multi card reader (built in USB OTG). The one with a blue mark is a USB C to Micro USB adapter.

Sadly what you're doing is way beyond anything I've tried. I'm happy when I can get card readers and stuff to work
I vaguely recall reading about specifications for the older micro USB ports on phones and what type of power output they supported - not all were equal. For example, there were a bunch of Samsung phones and tablets that could power hard drives without needing a powered USB hub inline. Similarly, some could power an MHL connection to a TV without the adapter being plugged into a charger like most phones that supported MHL had to. I've forgotten the name for these specs, but presumably USB C is exactly the same and it'll be online somewhere. No idea what your Terratec draws or if that could be the problem - if our phones can spin a 1 TB hard drive then perhaps it's not an issue, I was just clutching at straws.
Good luck!

4.7.4 Stock. Stock recovery too (not rooted either).
USB OTG worked on stock 4.7.2 as well.

Working fine for me, stock, custom roms etc. Use a cableconnection usb/otg cable 6" in length. Just enable OTG in the swipe down, plus USB stick in...no problems.

I gave up on using the phone for this because the audio quality via the FB app is terrible anyway, so I nicked my GF's Windows laptop and started using OBS for streaming instead.
Power aside, it's awesome that an external sound card will work (kinda) for recording though!.

LG G6 Otg doesn't work

I have a LG G6 H873 and I'm trying to use an OTG adapter to read an SD card (Kodlix Type-C Reader) and I'm not getting any prompts for a USB device being detected (and the LED doesn't light up on the adapter).
I've tried the same adapter on my wife's LG G5 and it works fine (both os are at the same revision). I've also tried the "OTG Troubleshooter" app which seems to detect that a OTG device is plugged in. Plugging a USB cable from my PC to this device works fine and I can browse the files on my phone from the PC.
Any ideas?

Same here. OTG worked fine. Then one day stopped working.

My phone recognizes all my files in file folder but stock gallery and music app showes no pics or songs.When i flashed oreo update my sd card worked fine.on boot up it would show media scanning and then show a little sd card icon in the notifications but after 2 days my phone does not scan anymore.Is this related to your problem?

I have a G6 h870ds. After loads of mucking about I have discovered that my OTG only works with full USB3 OTG adapters and USB3 memory sticks.
I cant use USB2 wired OTG adapters or USB2 memory sticks. Initial connection of the USB2 OTG adapter is recognized but no connected devices are detected. I have a USB2 memory stick with an LED on it. When it is first connected to the OTG cable it flashes in a way that leads me to think it is trying to reply to the USB bus interrogation but something (probably software) fails. The phone connects to my usb2 PC port just fine so I don't think the hardware is at fault. I've reset the phone but alas that didn't help!

No issues whatsoever if I plug in the OTG adapter first, then the drive. No matter if USB 1, 2 or 3 memory stick.
