[Q] usb otg gamepad question

I have an otg cable, yet none of my accessories work with it and my RAZR MAXX. My question is whether or not I need a powered hub when using the OTG cable. I have seen set ups of other android models using a SIXAXIS controller and otg cable, yet no hub. In this case, it the powered hub not needed since the controller itself is supplying its own power?
Thanks,
Neverused

USB controllers don't work?? I'm interested in this as well

When you open the app you should see 0 devices under Android and Linux tabs. Now connect just your OTG cable nothing plugged into it and hit refresh, something should show up, usually under the Linux tab that identifies the USB host. Even if the USB host doesn't supply power this will still work as I have tested it on my Touchpad which has no OTG power.
If you saw something appear when you connected the OTG cable, than OTG is in the Razr M. Now try connecting your gamepad and refresh the device list. If its not showing up then there is either something wrong with OTG or you need external power. This program will ID any USB device connected, even those which Android doesn't support since its just matching the device against a list it has. Try getting a USB keyboard/mouse working ad those are universally supported on Android and would confirm if USB host works.

Questions go in the question forum too...

Here's a dumb question. I just ordered a female USB to male micro USB. I wanted to be able to yank pics off my camera and drop them on my phone. Would I need an OTG adapter or does that plane adapter work?

An OTG cable has a extra pin in it that is tied to ground in a OTG cable which tells the hardware to switch to OTG mode. A regular USB cable will leave this pin open.

If I'm able to peel open this adapter that I got, and jump pin 4 to 5 should it work as an OTG cable?

Its possible, as shown here:

For me I'd rather just buy an OTG cable, but if you have regular microUSB cables laying around, go for it.

Bought an OTG cable
Bought a simple OTG adapter from newegg. So far....plugged in a mouse and my camera. Both work flawlessly, my camera gives me the choice of either either MTP (?) that goes straight to gallery and image import, or Storage which prompts to a new usb mount. Have not tried a gamepad yet, I have 2 floating around somewhere but not sure what game to try.

Usb otg on standard charger cable?

Hi there. Recently got nexus 7 there and I was not going to root or mess with it but the lack of otg cables around my area is
Doing my head in. But on my HTC one s I have a mental installed by a dev called zarboz. He got the standard USB cable that goes from the charger to the device working as an otg cable. Without having to buy a proper otg cable.
is there a kernel that supports this. I have been looking but have not found anything on it.

All kernels support otg. Even the stock. Some dont have automount for external drives, but I have yet to find one that didnt accept a kb or mouse immediately. Now, otg plus host mode charging is a different story.

OTG problems

Does the nexus 6p have OTG support? I have tried searching and didn't come up with anything definitive. Some say it works some say it doesn't. I currently have this OTG: Monster USBOM-0064-L 64GB USB 3.0 High Speed Mobile https://www.amazon.com/dp/B00S70GGKI/ref=cm_sw_r_other_awd_a92zwbV8J56A7
and this adapter

I can't get it to work. I am on Beanstown's Pure Nexus rom. Is it because of the pure nexus rom? Or is it my hardware?

I'm on Pure Nexus and OTG works fine for me. I'm not sure what your problem is but I don't think its the ROM.

What OTG device are you using? What adapter do you use?

I'm using a Kingston USBc 64gb jump drive.

Yea I am pretty sure the problem is my adapter but I think I am just going to buy a USBc OTG.

I picked up this http://www.amazon.com/gp/product/B00ZWN64RS and it works great!

OTG works but you need a USBc OTG adapter.
Using a USBc to MicroUSB adapter with a MicroUSB OTG cable does not seem to work.

I don't have write access as a user, only READ ONLY
I tried several known good USB drives. I tried several file managers. The system can write and reformat the USB drives. The Nexus 6P is not rooted. Is this normal? Any suggestions to get it to work? My head hurts from banging it against a wall.

Sorry to post dig, but ive got a working adapter but im seeing an issue:
- Sub 5mb per second transfer speeds
This is with es file explorer, but on other android devices with the same usb2 stick i cam easily get 14mb per second.
What speeds do you guys get?

I was able to get OTG working when I got this adapter ( https://www.amazon.com/gp/product/B017MP658G ). Not every device works on it, however. Several USB thumb drives have worked with no issues, one inexplicably does not. Also, and more disappointing, is that my USB to SATA adapter doesn't seem to be recognized. I have a 120gb SSD that I used this method with my LG G3 and it worked fine.
Maybe it's the adapter? Changing setting from "supply power" to "transfer files" does nothing to change it. It sees there's a USB attached, but doesn't read the format.

I've tried several USB to type C adapters with stock Nexus 6p. All of adapters had USB3.0 support, it's important. They all worked fine with USB2.0 flash drives and they all didn't with USB3.0 flash drive. I've ordered some adapters USB2.0 to type C to test.

UPD: I've tested six USB to USB type C adapters with both USB3.0 and USB2.0 support - they all not working with USB3.0 flash drives and work wine with USB2.0 flash drive. Also: the phone can recognize the drive but can't mount it.
I'm sure this is the phone issue - I've seen successful mount of my test flas drive with one of adapters on some Xiaomi phone.

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.

Has anyone tried the type c OTG and not the micro with the adapter?

I'm on stock B10 (A2017G) and have successfully used an OTG type C cable to transfer files to an external 3.0 HDD. It was fully powered by the phone.

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.
The USB-C to USB 3.0 Adapter I got is the one below:

USB OTG

Does anyone know if the US unlocked version supports usb OTG or not?

It works natively with my micro USB drive. I haven't tried plugging anything else in though.

I have the Amazon version of this, and I was able to use a USB ethernet dongle for networking (till I got my SIM). Splitter let me add a thumb drive, too.
Seems a decently implemented OTG, AFAICT.
