Really nice to run across this! I have a 1TB WD Passport, OTG cable, an Anker external battery, and Nexus Media Importer and they work great with this setup. I had tried a powered USB hub and it worked but this is much better from my perspective - hadn't thought of trying the battery pack.
Interestingly, I also have 2 500GB WD Passports that worked without additional power on my 2012 N7 but they won't work without additional power on my 2013 N7.
Thanks for the post!

yes, im currently on cm10.2 m1(milestone) rom with stock kernal. playing videos straight off hd tends to reboot my device. Let me know if you get similar issues. i find copying the file into the sd storage is the most stable way. hopefully CyanogenMod will come up with an update that corrects this problem

It works with any hd drive that doesnt require an outlet plug

Is it possible to use a USB hub, connect the HDD to the hub, mount the HDD and then connect a SD Card reader to the USB hub, mount the SD card reader and transfer files from the SD card to the HDD??

No. It appears that a single external drive/memory device is the limit (at least on a stock unit).

I forgot to ask before, does this require rooting?

Yes, and an app like Nexus Media Importer to access it. I'm actually assuming that it will require additional power, like my 1TB WD Passport does - I haven't tried this particular model myself.

ahh right need that app too okay thanks. I will give this a try after I move and settle in.

Clarify cable connection
I don't understand. How do you have it cabled? For example, I have a limefuel 15600mAh battery with a microUSB input (for power) and two USB outputs to power a device. How are you cabling the Passport to the battery and then to the Nexus?

Probably are - Amazon was convenient. As for speed, I don't have a way to measure transfer speeds but I do know it is fast and in no way impedes video file viewing direct from the HDD. Using on a laptop, I can see that it does give true USB 3.0 transfer speeds.

You don't really need the Nexus Media Importer app to access external hard drive files.I'm on Cm10.2.0 and I'm using ES File Explorer to access the files. I do get random reboots due to the Nexus overheating say after an hr of video play directly from the HD.

True - I was responding from the perspective of a stock device. I haven't seen the reboots - are you overclocking with Cm?

Otg type-c adapter problem

Hello everybody, i just received a usb type-c to female usb adapter (made by Victsing®) from amazon on this link amazon.fr/VicTsing-Adapteur-Convertisseur-Chromebook-appareils/dp/B017I8A40CUnfortunately it is not working on my oneplus 2. I plugged a mouse, xbox 360 controller, usb pen drive and it didn't even turned on. No lights, nothing...
Is there any tweak or app to instal to make it work? My opt is rooted and xposed is installed.
Thanks in advance!

after looking through many forums, it seems that the issue is that OnePlus has used a slightly different setup with a 2.0 usb type-c connector so it doesn't work with anything other than their first party connectors. I have tried to connect a kingston data traveler microduo 3c and it isn't recognised either

So the issue is a hardware problem i guess, only solution is to buy their usb type c to micro usb adapted and then plug OTG cable?
So there will be no software fix...

Where do we find this orignal convertor

It may be possible for them to provide an update that creates a workaround to the problem however that does not seem very likely, i guess we just have to wait and see

the original converter would be on the oneplus site or i have heard they are also available on Ali Express

So not in India yet i guess

Hmm... I have the original OTG cable from oneplus, 2 other OTG cable ( 1 is USB 2 and the other works both with USB2 and USB3 with power up mass storage) and none of them work for my OPT.... HOWEVER they work for my OPO.... fking oneplus....

Thank you for your responses.
Hope that android MM or CM will give a solution!

i asked the oneplus official, they said ONLY THEIR OTG adapter can work with OPT...
and what's worse, they are currently out of stock of this stupid adapter! They told me to visit offline shops. oh are you kidding?

well that sucks. I was planning to buy a OPT but decided not to. they decided to leave quick charge/turbo charge alone and made some modifications on their port so only their product would work. what about the countries where it's hard to ship a product. damn this is lame

I bought a third-party USB-C to Micro-USB adaptor from Amazon that works with Micro-USB OTG drives and my old Micro-USB OTG cable with a USB mouse & USB memory sticks.

Thanks for reply I'll try this method.
Anyway I bought an OTG adapter (uUSB) and an uUSB-TypeC adapter (Xiaomi) and it works! (seems the problem is type C otg are always 3.0 op2 does not support USB 3.0 standard)

Mmm tbh I only use my USB stick and that always seems to work okay. USB C is just future proofing got to wait for rest to catch up now.

USB-C Hub - no keyboard/mouse or HDMI signal

Hey guys,
I got me an Aukey 4 USB+HDMI, USB-C hub. I've plugged it in but can't get anything to happen. I plug in a USB wireless mouse, nothing happens. I plug in a USB keyboard, nothing, no lights on shift lock/num lock, nothing. I plugged in an HDMI cable and, although the screen seems to be getting signal (It doesn't auto-power save) i can't get anything to show on it.
Have I bought an incompatible hub? Am i not doing something important?
Thanks!

are you conecting it directly? I tried to read a sd card just using the little adapter and a card adapter, and, could not, then tried with the BIG ONE included, this time it worked, mi conclusion is that you need always this BIG adapter in order to read external, mouse, keyboard, etc.

The little one is not usb otg compatible!!!

But then what would be the point of USB-C port if you have to adapt it back to a standard USB port? In addition, you would probably also lose the video functionality.....
I'm beginning to wonder if I needed to buy a powered USB-C hub?
edit: btw, I have a USB-C micro-SD card reader and it works fine directly connected although, it only works one way up, so much for being a reversible format!

From what I know Note 7 don't has MHL, so cannot connect to HDMI.

You plug the USB C end into the Pixel and then use another cable to connect an older phone (presumably one you're already using with the older phone). Micro USB/Lightning into the older phone, USB into the adapter. The adapter can also be utilized for OTG - USB C into the Pixel, flash drive/other USB device into the USB port.

Also to use OTG. Plug that in, and you can hook up a keyboard, mouse, removable drive, someone elses phone, whatever.

Could someone clarify. I plugged the adapter in how I was directed by a thread at the "pixel community". The thread referenced a way to use the adapter to transfer files however I plugged it in set the settings to xfer files and nothing. Does the adapter go into the pixel or the (in my case) Note 7? The thread listed a way to make these transfers upon start up but I'm way past start up. I need to transfer a couple apps and a big phone log and a truck load of texts. Any help out there?

USB OTG Poorly Supported

USB-C to USB-A OTG Cable -
Not able to power a simple external USB MSata Drive or External USB HDD - I plug these drives into a LG V10 or a Galaxy S8 and work perfectly fine. What gives? I have only able to get a flash drive to work.

I wonder if OTG power support was removed due to the decrease in battery size? Has anyone tried OTG "audio output", say through a device like the audioquest dragonfly, to see if that works??

I don't think so, since the notification that pops up when I connect 32 GB ADATA USB 3.0 flash drive -> USB 2.0 A female to micro-B male OTG cable -> micro-B female to USB-C male adapter -> Z2F says the Z2F is providing power to the connected device. The problem is you can't do anything else BUT that.

I'm wondering this myself. The fact that the Z2F outputs analog audio over USB-C leads to me to believe that it isn't fully USB-compliant.* Both the HTC U11 and Google Pixel 2 output digital audio, which, based on Google's crowing about USB-PD and the existence of devices like the dragonfly, appears to be the right way to do things (albeit with the tradeoff of more expensive audio peripherals, which much now have their own onboard decoding hardware.)
*Can anyone with knowledge of the USB spec comment on this?
BTW, I started a support thread about this at the official forum, where it's received several replies and suggestions from a mod. Kindly chime in there too so Lenovo can see this is a real issue they need to address.

So based on this Motorola mod post and the OP's statement that USB-C flash drives work, the Z2F and Z have the same (lack of? LOL) OTG functionality. The Moto Z subreddit has a pretty extensive thread about Moto Z DAC functionality; it appears the Dragonfly is supported, among others.

Interesting development: another Motorola Forms mod now says powered USB hubs are rumored to work. We're making progress, folks.

Okay fellas,
I so far have been able to get certain drives to work and others not! I have tried 2 different USB-C to USB-A cables and get the same results, 1st ones an HP cable and 2nds an Anker USB-C to USB 3.1 Adapter
https://www.amazon.com/gp/product/B01COOQIKU/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
I have been able to get a 256gb M2Sata Drive, 500gb WD Mypassport, and a 2TB Mypassport to read.
I also have a 256gb MSata Drive that will not power up or read without using a powered usb hub. However the Msata Drive will read without an added powered HUB. On the Samsung and LG Devices.
Only thing I can think of is that certain drives have higher amperage that the Moto Z2 simply cannot push through its USB-C Port.

Good to know it isn't just me experiencing broken USB OTG support.
I've got a PS3, PS4, and Xbox one controller I hook up with USB OTG. Normally it's as simple as plug n play and I'm good to go. However, that doesn't seem to be the case here. I can still pair the PS3/4 controllers in sixaxis just fine and get power to the PS3/4 and Xbox one controllers. And yes, that bit about supply power to device rather than transfer and you can't pick something else, happens to me too. Sometimes I can plug my thumb drive in and I can explore through the storage file explorer, but I usually have better luck with an app called X-Plore.
This one time I even had said thumb drive take out my entire OS to the point where I had to use that June ROM to reset me back to start. Spoiler alert: I kept getting "Android.process.acore keeps crashing" over and over; various other apps kept crashing as well.
On a side note if I can at least get PS3/4 controllers to work for a long time within say, sixaxis (or similar) I'd appreciate any tips. Otherwise I either gotta wait for this to be solved in a future upgrade, future sixaxis, or when we start getting custom ROMs..

The latest Neutron and USB Audio Player Pro will output bitperfect (non upsampled) audio perfectly to both my portable DAC/amp units.
USB Audio Player pro, has the benefit that you can stream tidal native, bitperfect if you have an acct. Which is awesome imo. Tidal still buffers SUPER slow on this device though. So I'd recommended only offline use (which you CANT do with USB audio player pro due to licensing)
I would also add that I get some scratchiness out of the stock USB C to 3.5mm dongle that came with the phone. I thought it was the port being "dirty",. but I have NO NOISE out of the USB audio output using the Anker otg cable. Maybe Anker makes a USB c to 3.5mm adapter.

One tip for getting USB powered OTG drives to work is to use as short a USB cable as possible. Like get a good quality 1ft USB cable. I used to have a similar problem with using an external drive on a Wii and found that a 1ft cable would allow me to use 2 different drives that otherwise would not work with a 6ft cable.

It worked!
I used a USB 2.0/type C adapter that cames with s8 and instead the original USB 3.0 cable, put another adapter, and transferred files with Total Commander.

On this subject but kinda off topic. How are you all getting your drives mounted? I cannot mount NTFS or fat32 drives. Only ext3/4 drives.

Yep, basically you created a 2 inch cable. LOL.
In essence, many USB powered hard drives approach the power limit of what the USB port can output. Power drops over the length of a USB cable, so longer cables may not provide sufficient power for the drive to function correctly. Better quality cables usually have less power drop, though it is not a guarantee.
Unfortunately most USB powered drives do not list their power requirements. The only way to really tell is to open the case for the USB drive and look at the hard drive inside it to find how many amps it draws. For the best compatibility you want the lowest amps.

I don't think that's otg power issue. I think it is locked by Moto becuase they want you to use their add-on devices. I have a wifi camera it doesn't work either, But it works in my all other phones

Just because an add-on device works for one USB OTG implementation doesn't mean that it works on all USB OTG implementations. There is an enumeration of what devices and types are accepted. I have tested USB OTG audio microphones, USB OTG audio speakers, USB OTG Headphones, USB OTG Ethernet, USB OTG Keyboards, USB OTG Flash drives and those device types work. If there is no device driver for the device attached then it would need to be supplied by an app. OTG power drain is definitely an issue and is mentioned in the OTG specifications.

That's what I tried to say. It is locked by Moto. They want you to use their add-on mod. I have tried extrenal usb c endoscope camera, wifi endoscope camera, lg wireleas projector, Samsung projector. None of them work with Moto. However, the same apps work in all other phones. It is clear to see, it is not all otg related all the time or driver which provided by app. It could be just locked by Moto, becuase they want use to use their mod add-on. People who rooted the phone was able to turn on those supports.

I use a Belkin OTG adapter, it worked but it was extremely picky. The Built in files app only picked up my HDD if it was either Fat32 or exfat. But the ES File Explorer app only picked up NTFS.
