and how is it different from MTP?
usb host on the go.
Means you can use an adapter to plugin controlpad/keyboard/etc..
-m
It has nothing to do with MTP.
Basically allows you use flash drives, mouses, keyboards on your phone with an adapter. Probably... microUSB to full-size USB.
USB On-The-Go, often abbreviated USB OTG, is a specification that allows USB devices such as digital audio players or mobile phones to act as a host allowing a USB flash drive, mouse, or keyboard to be attached.

oh... that's it? With all the ranting I read about the phone not supporting usb otg I was thinking it was something more important like not being able to transfer files easily.
Why would you want to hook up a keyboard to a phone?

Who knows? lol. the flash drive could come in handy though. It'd be expandable storage OR! if you have a ASUS transformer, you can hook the transformer dock with the Galaxy Nexus and you'd have a portable charger with you that can transform into a netbook or a tablet or just into a charging station
so, I could hook up a USB hub and connect a mouse and keyboard (USB screen ;-)?

One reason would be so you could type on it without using the on-screen keyboard. I have a bluetooth keyboard that I use with mine sometimes. If I added a bluetooth or USB mouse and MHL adapter to a monitor or TV, I'd basically have a complete usable computer.
In some cases it might be very useful, in others it might be more trouble than it's worth. Some people might like it, others might think it's stupid. Regardless of any of that, I think it's pretty cool that it can be done and that the lines between phone/tablet/laptop/desktop are becoming very blurry these days

I want to attach two usb devices to my Note.
One will be the MHL adapter and one will be the 2.4ghz wireless unit for a keyboard like this http://www.ebay.co.uk/itm/250996855143.
I need a Micro USB male to 1x Micro USB female and 1x USB female adapter.
These for some strange reason don't exist
I was just wondering if anyone has done anything similar.
I know I could get a Bluetooth keyboard, but I don't have one. I do however have the above keyboard
Oh wow! I'm interested into this keyboard! Does Lenovo Mini Wireless keyboard work perfectly with the Note? All buttons are recognized and trackball mouse is usable?
Its really good, i use it on my Note and my Libretto W100. The mouse and keyboard work perfectly.

You cannot attach 2 or more devices to the same usb port. You need an usb hub for that, but I don't know if the MHL would work with the hub. I will try later today to attach an usb hub and connect more devices, and will report my findings.

--------------------------------------------
I have successfully connected a self powered usb hub to the galaxy Note, and connected 2 thumb drives, a combo card reader, and a mouse. The Note mounted both of my thumb drives, as /usbstorage/sda and /usbstorage/sdb respectively. Then I inserted a mikroSD card into the card reader and the phone mounted it as sdc. I then inserted an sony memory stick into the card reader and it was mounted as sdd. All mounts were usable, and I could watch movies from them, and watch pictures, copy files from one to the other, etc... But, when I connected the mouse to the usb hub it didn't recognize it. Whatever combination I tried the Note would not recognize my mouse, when plugged into the usb hub. When plugged directly to the OTG cable it works perfectly, but won't work when connected to the hub (maybe cables are to long).
Using rooted stock xxla6 firmware.
Edit2:
---------------------------------------
Just found out, that usb otg and mhl cannot work simultaneously. When the MHL cable is plugged in, the GNote's microusb port will become an MHL port, and from that point it will not act as an usb host or usb slave. :-(
It's too bad, 'cause I really wanted to connect it to my full hd monitor and use a mouse and keyboard, too.

How about bluetooth mouse+keyboard instead ? That would keep your USB port free for MHL

This is the setup I'm going to do also. But as with topic, it's also very tempting to have everything USB powered. Since it will decrease latency and maybe power consumption as well? (as opposed to bluetooth) Well, MHL to HDMI will still drain our battery even if we connect it to power source

Hi i wonder where i can buy a microusb splitter for my phone so that i can use, both usb keyboard and hdmi cable together. I just tried keyboard+mouse using a usb hub, and it worked fine...
does it even exist?
Sorry, but this can't work. When the phone is putting out HDMI, the USB can't be used as it takes the same connector pins. You can do what you want with a bluetooth keyboard and mouse, but sorry, not with wired.
try to find the smallest hub there is, that's the closest you will get to a usb splitter that works. Just splitting will never work, the signals have to be divided with some intelligence.
/edit... never mind didn't read the MHL/HDMI part... don't think that will work
I am also intrested in this topic. I want to plug in the HDMI cable and s remote controler. I want to use my phone as a media center.

You flat out can't; it is a limitation of the more common MHL implementation, and the Galaxy Nexus uses this MHL implementation.
Samsung had to use a new kind of MHL connection for the Galaxy S 3 to make this exact scenario possible.
*edit* You can plug in an HDMI cable and use a bluetooth remote, though, if that might work for your needs.
Hi folks,
As I understand it, the Glide supports both HDMI out and USB On the Go. What I'd like to do is set up my phone to be a basic laptop.
The first part of my plan is to get the right cables. Does anyone know of a combo cable that provides both HDMI female and USB A female to the phone so I can hook one end up to a powered hub with an ethernet dongle and keyboard/mouse thing, and at the same time hook up an external display? Also, if I do this, I assume the hub will need to provide power in some way back to the phone. Is that correct?
Or is this going to be so expensive I should just use a cheap computer?
Thanks.

Assuming a computer on site, you could always vnc.
From past experience with other PDA's, you will -quickly- grow tired of this and end up purchasing a laptop anyways.
Not that you'd want to be internet'ting, much, on a TV, either. For anything short of a quick search, weather, TV guide, you're going to want to cross the room to your laptop, IMO.
Which is probably what you'd have your HDMI connected up to, anyways. Although using the Glide as a remote in that situation is probably attractive. Or as an XBMC control sort of thing, but, again, likely the content would come off the computer rather than the glide, the glide just remotely controlling it.
You can easily test how you find this, either by using a bluetooth keyboard and playing (never mind the external screen for the moment), or by vnc'ing to it from a computer (pretend it's a bluetooth keyboard and it's an external monitor, for the moment).
Technically possible, not practically feasible.

Just get cheap laptop. It will serve you better and will be much easier to use

HDMI out is supported by the SoC, but to the best of our knowledge those pins aren't actually connected to anything in our phones. That said, there's a protocol for outputting to an HDMI device via a USB dongle that doesn't require any hardware infrastructure beyond USB OtG, which we have.
In theory, you could get a powered USB hub (it MUST be powered, no way in hell the phone can put out enough current to support all this), plug a keyboard and mouse into it along with one of those USB-to-HDMI dongles, then hook the phone up to it as a host using an OtG cable. At that point it's just a matter of ROM/kernel support of all the peripheral hardware. (Ask dman? Nah, I'm sure he's WAY too busy.)
If you are just using it for media as like an htpc, I'd reccomend skipping all the usbotg stuff and just connecting a net book or some other cheap PC to your display.
My current setup: old netbook with 1tb external hooked into TV, controlled by the glide (unified remote app) and the external drive is also network shared so my glide (and tablet) can read from it.
Its served me well for playing all of my local video files as well as flash video and light browsing. Depends what you're using it for though, I suppose.
The only time I've ever really used HDMI out with android is to play n64 emulators (or other games that support a bt controller) or if my girlfriend is watching desperate housewives or something on the main setup. It works well enough for that, but not enough that I would make a habit of it.
I have an acer aspire 7560, it does have an hdmi port, but I don't want to have to buy an adapter for something that I don't know would even work for video input. I want to know: is there some way that I can use a normal, oem supplied, usb cable for this and simply connect it to the computer, figure out some stuff on the ubuntu end, and just use my laptop as an external display?

Short answer: no
Explanation: your HDMI port is solely for outbound connections only, to a TV or monitor. There are very few laptops that have the ability to receive an HDMI input.
As for doing it with USB there are third party apps like BBQDroid and MirrorOp that will let you, but its nearly impractical for the Nexus. Trust me, I've been trying for over a year to get even the right ROM/kernel combo to maintain a reasonable lagfree experience using them and its hopeless. We don't have the power. Sure, you can do it. But don't expect to do anything without huge performance drops.
I have a new tv that supports hdmi, but it also has usb 2.0 in, and I do not have a hdmi mhl adapter. Would a normal oem cable work for that?

Nope. USB port on your TV is for connecting media devices with music/videos/pictures and does not support the feature your looking for.
I have had success using the Mirror for CM11 application by koush with Airserver on my PC. Info to get it here. You must join the community and beta before it shows up in Play Store.
It works over WiFi network so long as your PC has AirServer, which is an Apple app supposed to be for idevices but the app picks it up anyway. The free version of Airserver is only 7 day trial. It will slow your phone down somewhat, but not anywhere near as bad as other apps. I've used it some, and it works well. But it has limited use with only a trial for Airserver. Such a bummer there, but give it a shot for the 7 days and support it and koush if you it
Good luck
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.

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.
