Otg support ?

Hello everyone,
Is the pixel c support OTG ? can i use an usb flash drive with the pixel c ? thanks a lot
On twitter Google store answer me : "Mind if we jump in? The Pixel C does not have USB OTG. Hope that helps."
Thanks a lot

Yes. It does have OTG. I have tested it with a USB-C hub and was able to use a usb flash drive and Ethernet my device.

Can you post a link to what your using for a hub?

Hub here works great:
DBPOWER, Hub USB C , 4-Port USB 3.0 Hub for type c devices like the new MacBook, ChromeBook Pixel, smart-phone Nexus 6 and OnePlus 2 (Grey) https://www.amazon.co.uk/dp/B014UPCWDS

Is it correct that this hub doesn't have power pass through to be able to charge the tablet?
Really like the hub, but didn't buy, as I'd like it to power the tablet too.

I picked up a Griffin USB-C to USB-A adapter, plugged it in to my Pixel C, and plugged a memory stick into the cable. ES File Explorer recignized the memory stick immediately. On the box for the cable it stated that it was for plugging USB peripherals into your tablet.

With so many cables not passing Benson Leung's tests, I am a bit unsure with USB-C OTG cable I should get. The original one from Google is 15 € which is kinda expensive...
Does anyone know if he reviewed some USB-C OTG cables? I can't find anything.

It only has full size USB a ports, so can't plug in a charger no.
The battery life is great on he Pixel C though, so all good

I did see that one, but wondered how it would work with the ucb-c in the position it is on the pixel c? mabook its on the base, but c its on the side of the tablet.

Type C is reversible so it should just flip up like ?
Edit: and I wasnt questioning you I was more posing it as a question to myself But it should just go up the side of it

I agree that you could get it to fit, but not sure I'd want it facing straight up with my cables and sticks attached.
Seems it would stress the port or worse I'd catch it and cause some damage.
I'm thinking of this -> http://www.amazon.co.uk/Galopar-Cha...qid=1450272359&sr=8-22&keywords=usb-c+adapter with a standard usb3 hub attached?

Looks great, but how do you know it is compatible? After Benson Leung's reviews on USB-C cables, I am afraid to purchase any third party accessories...

Short answer is I don't at the moment, as have not had a chance to look at the online spreadsheet to see what he has tested and approved.
Will hopefully get to look later.
Sent from my D5803 using Tapatalk

Does not appear to be included in the spreadsheet, so likely he has not reviewed.

I tried Google's own USB C to A (female adapter that looks like a otg cable) with a memory stick and it did not work, however I plugged in a USB2 hub into that adapter and then plugged the memory stick into that and it sees to work like a charm with esexplorer, I could also attach other things like a mouse and that worked too at the same time! So the trick is to use a USB hub with Google's adapter first and you can use any USB accessories just not directly into the adapter. I have not tried a USB 3 type hub as I don't have one but I suspect it will be fine and give you even faster speeds.

There are lots of OTG devices that work perfectly on my Nexus 5x - such as a microSD adapter, USB C ->A with a thumbdrive and my iRig UA guitar adapter
None of these work on my Pixel C.
I just got off a chat with Google support where I was told
"I'm sorry to inform you, at this moment it's not compatible. Be rest assured [sic], our engineers are working on a software fix to make it compatible with the Pixel C."
I responded with a link to the reddit AMA which seemed to state otherwise and the support rep told me that she'd get back to me via email with a response.

You can try plugging a USB 2.0 or 3.0 hub into a USB C>A adapter (mine was the Google adapter and the hub a USB 2 unpowered type) as I did and and that worked for me and I can now access Memory sticks on my Pixel C with no extra software (not sure about your iRig but it worked with other accessories I tried plugging into the hub).

Thanks, I'll try with a hub. I just don't understand why a hub is required for the Pixel-C but not for the Nexus 5x
There certainly seems to be a less complete stack in the Pixel-c -vs- the Nexus 5x.
Interestingly when I insert a cable into the Nexus 5x I get a dialog to set the usb mode:
"Use USB for
- Charging
- Power Supply
- File Transfers
- Photo transfer (PTP)
- Midi"
Where as the Pixel-C only gets "Power Supply" as an option.

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 to HDMI

Has anyone gotten one to work I bought 2 from Amazon and none seem to work. Maybe I thought wrong but thought HTC 10 has displayport output.

I've tried 2. One worked, one didn't. Both were designed for macbooks, so ymmv.

I will try this out when I get the chance.

Tried one at the Computex last WE, for MacBook. Didn't work.
And after I tried the HTC10 and put it back to the MacBook it didn't work at all anymore.

damn thats not good news. still haven't had the time to head to local bestbuy. Hoping someone got one to work and point to an amazon link really miss having to show movies (for my kids) on the screen. Still have my MHL adpater for htc m9.

Adapter needs to use display port protocol, not mhl. Some adapters (USBC to HDMI) will use mhl internally and won't work (to my knowledge). See USB-C thread in 'Real Life'? section.

Yes I know can't use MHL for HTC 10.. Just saying I miss that feature. And almost nagging at me still is the MHL cable. starring at me saying why did you get of the M9 [emoji14] you could be watching videos on the 70inch right now.

Buy your nagging mhl cable a baby sister; a USB-C to HDMI port adapter / hub. It uses display port protocol and supports 4k. Adapter also includes USB 3.0 host port (so OTG) and 2nd USB-C port (for charger connection, I think optional, but I always use). Charge phone and watch at same time. See referenced thread for source. Win-win but approx $30. Need standard HDMI cable. Works well for me.

I ran into the same problem the mac pro adapter, it would charge or display not both. I went this route Microsoft - Wireless Display Adapter V2 receiver - Dark-Titanium and use HTC connect. It works great.

Just curious... you've had no problem charging this way? I wasn't sure if the 10 could take a regular USB-C charger or if it needed a QC compatible charger.

Partial answer. The HTC-10 does not need QC2 charger, just might charge slower or at various rates supplied by charger. I use several different chargers I had for my micro USB phones. Both using micro-USBC adapters, and USB-C cable direct. What I haven't tried (per your question), is fully charging via the mentioned display adapter. I doubt that the will recognize it as QC2. I will try this with the HTC supplied charger.

Is this available anywhere else? I was hoping to find this or a similar device on Amazon or something but nothing else has been confirmed to be compatible. Is your experience with this device still a positive one??
Also, I am assuming that if you want to supply charging power to this device you need to use a non-QuickCharge charger as supplying greater than 5V to the electronics in this device would be bad...? What about still using legacy USB-A to USB-C cables (like the one that came with the HTC 10) with the 56K Ohm resister?

USB-C to HDMI for A-series 2017

The Galaxy A-series 2017 have USB-C. But do they have HDMI out over USB-C?
I tried the official Samsung EE-HG950 adapter but no dice. No image.
There can be displayport alternative mode and MHL. I tried also my older Micro USB MHL 1.0 cable with the included microUSB -> USB-C adapter and also no luck.
The adapters are quite expensive. 30-50 bucks.

any news or answer on that issue?
hi,
i'm also interested in any info or answer on this issue. any news? is it working and if so how? i saw some cables for this device but could not test it!
thx br s0uli

Tried a USBC to HDMI adapter which qorks on Galaxy S8
Test was not good because it do not work.... so i guess only a special cable will work on A3 2017 but not the standard cables or adapters for USB C with 3.0 or above.

USB OTG Poorly Supported

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.
