hi first i am a noob and learning meanings of terms used.
I have looked at threads with similar titles but they appear to be having a different issue.
Back ground history.
My SD card ext fried with all its data so I decided to go down the route of using an usb stick for storage. I am currently waiting to receive a usb 2.0 stick which can both be plugged directly into the phone or via my otg cable.
In the meantime my Problem has been experienced connecting a usb 3.0 stick to an otg cable. My phone does not recognise that the usb stick is connected. The otg cable is ok. I have used it to type on a keyboard. Previously.
When I plug the otg cable in the symbols come up at the top left corner of my phone showing that a usb connector is plugged in. I go to look at my storage and there is mo usb there. My usb debugging is ticked. if i have a look under usb tethering the option to tick is muted as it dirsnt recognise the usb is connected.
I did briefly see a suggestion somewhere that it could be a kernel problem but have been unable to locate the thread that this comment referred to.
I have a note 3
sm-n9005
a couple of days ago I managed to root it using towel root and downloading a link via this forum to revert the kernel to an earlier one so towel root would work. I then followed the link instructions to install the second kernel. The root appeared to work without too much problem. i ran root checker after and it said all was ok.
I am unsure whether the root has any relevance to the problem as when I google the usb stick is not recognised there are heaps of similar problems. Unfortunately though I have read many of the threads I still cant find an answer that helps me.
Could you nicely give me some advice. Thanking you
How was the USBstick formatted? Android can't use NTFS, you need to format it as FAT32 or ExFAT.
Well I was prepared to look extremely abashed on reading your question to me reformatting. luckily abashment could be deferred this time.
On looking at the usb stick it was formatted as a fat32. So I tried the other type of formatting you suggested. It still was not recognised.
The computer could recognise it.
My friend had a usb stick 2.0 which I then plugged in. a eureka moment was experienced. Mass storage message appeared.
So the problem appears to be with usb stick 3.0
I know the otg cable was originally designed for the 2.0, my understanding is that it is also supposed to work with 3.0
Any thoughts of why not?
Btw still havnt figuered out how to use the forums thank you process (where it is located?) Would love advice with that as well.
Thank you

USB 3.0 is actually USB2.0, the small addition on the side is the 3.0 part. It's completely backwards compatible.
It could also be an issue with the OTG cable itself. Do you have any other device to test the OTG cable with? (Tablet, etc)
Oh, the thanks button is located bottom left of a post, at the bottom underneath the poster information.
Thanks for the reply. I guess this will remain a mystery. I must admit to scratching my head about the possibility of it being an otg cable problem as the phone recognises when the cable has been plugged in and the cable works with both keyboard and usb stick 2.0
All I can think of is that elusive past post referenced on xda forum that referred to kernel issues.
Many thanks for your responses. (Still cant find thanks button) could be because I am using phobe as I dont have a p.c.

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.

Hey guys, quick question for those of you with the s5, and the usb 3.0 cable.
I am trying to transfer files from my windows 7 pc. with the usb 3.0 cable.
USB 2.0 works just fine, I switch over to usb 3.0, and the phone immediately dissapears from my pc.
Switch back to 2.0, and it reappears.
Is this happening to anyone else?
Maybe you have a faulty usb 3.0 cable. Try with a different usb 3.0 cable. If it's not the cable try on different computer. After that remains only one possibility: a faulty usb connector which means service. BTW you have usb 3.0 drivers installed on your w7?

Yeah i have a problem with the usb 3.0 too..
When i connect my phone via usb 2.0 it works fine but when i connect it via the usb 3,0 its still only shows up as a usb 2.0 device and the both only charge at 98ma :-/ brand new usb 3.0 cable. unistalled usb 3.0 drivers still no luck.

I've got this issue as well....
except when I attempt it on my work PC with W7 x64 it works in USB2.0 and USB3.0 mode. At home on my W7 x64 build it shows up under my computer in USB2.0 mode but disappears when switching to USB3.0 mode....
tried reinstalling drivers and all that jazz and no luck.
tried two USB3.0 cables and neither work on my home rig. i'm stumped
Plug in another USB 3.0 device such as a memory stick into your computer to determine whether the issue originates from the phone/USB cable or your computer. From what you described we cannot identify the root cause!

I had this issue too, then found it was my motherboard being the issue, i turned xHCI to on instead of auto (in the BIOS) and now when i connect my S5 with USB 3.0 cable the option for that mode will show on the phone.
Auto should work but it didn't seem to allow the S5 to trigger it, maybe because the S5 defaults to USB 2.0 and then you say to it to use USB 3.0
I do notice when switching modes the phone will vasish from the computer and then after a moment or 3 show up again
http://www.tonymacx86.com/lion-desk...te-uefi-motherboards-xhci-mode-explained.html
fiddled with bios settings on ASUS mobo... still no luck
a) Click on “Start” and Right Click on “Computer” and select “Manage”.
b) Now select “Device Manager” and Right Click on the individual “USB controller drivers” and select “Uninstall”.
c) Restart the computer and check if the issue persists.
if the cable is a cheap one that claimed to be usb 3.0 from eBay bin it and buy one from a decent retailer or Samsung
thanks for the ideas, tried device manager uninstall and reboot. still no luck. I"m using the provided samsung usb 3.0 cable so no issues there. very frustrating I cant use my phone connection to it's full potential

Old thread I know but here is what seems is the answer.
It seems when first connecting the usb it always defaults to usb2, but then can goto the usb settings on the phone afterwards and switch to media usb3 mode. I have not found a way to make it default to usb3 mode.

Appreciate the post but the issue wasnt actually switching into usb3 mode. That I knew how to do, it was that when I do switch the phone to USB3 mode it disappears from my file explorer and I cannot access the phone storage media unless I switch back to USB2 and then it pops up again in file explorer. I still havent found a solution and have come to the conclusion it is a hardware issue likely tied to my motherboard and have just accepted it and used it in it's limited form
I don't even see any option on my S5 to switch to USB3.....
Is this option device-specific?? I have the international version SM-G900H
Edit: never mind....the cable I had was a fake....
I tested my S5 with a cable from a USB 3.0 external hdd and it worked...

So are you saying that if the cable is faulty (or in other words, USB 3.0 is not achievable with the current connection) that the USB 3.0 option simply does not appear on the phone? That may explain why I am also only seeing MTP or PTP with a 3.0 cable and hub
Reading these replies and I still don't have a solution.
I have a Lenovo P50 ThinkPad and I normally connect my S5 via USB 2.0, but I'm wanting to transfer about 20gb of files off my microSD card to my machine. When I connect with 2.0, I can't even get the entire folder to show in the navigator window.
I tried to connect to the 3.0 ports, which I use with my external HDD with no problems. I'm even using the same cable.
And yes, it's a legit 3.0 cable.
Still no solution...
Did you find a solution?
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 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.

At the top of the screen from the notification area, it showed USB icon and you can click on it to see files.
I didn't found solution for my problem, and i think there is no need to open new topic, but if you know - help me!
From purchase my H870I had a problem with USB OTG.
When memory card micro SD is inserted and mounted, everything is working properly.
When I connect USB OTG USB adapter with USB flash drive, or USB OTG memory card reader, then in notification area is "Android System - Reading USB Drive" all time.
In System settings - storage
is the information about internal memory and and memory card capacity and usage, and "USB Drive - checking"
In that state a cannot access any file on memory card. For example I can see photos and albums, but after opening one of them there is icon, that file is corrupted.
I need to reboot phone to memory card work properly again.
To see files on USB OTG device i need to unmount memory card in settings, and then plug USB OTG. After unplugging USB OTG I must mount memory card again.
Did you have a similar problem? I must say, that back to factory state, and oreo update (also last ThinQ update) didn't resolve my problem. Do you have any solution? Can you give your ideas to resolve this problem?
I'd try a second usb flash drive. If you get the same hanging issue, I'd expect it's something bad with your usb otg adapter. Sometimes an adapter might work okay with one phone, but be kind of on the hairy edge and not work with a second phone.
I use the anker usb c to usb otg adapter a lot with my g6, since I first got it over a year ago. I do transfers to multiple flash drives.
Good luck!
I tried a different USB card reader, and it's working perfectly. Thanks for help!
Hi,
So I'm developing an app to communicate over serial with a HID and testing on the g6 is proving troublesome.
The scene:
-Hid/USB Permissions granted
-Device filter correct and working as intended
-Goal is to send a string over serial.
Allthough I'm 100% sure my test code is correct, the app cannot open a serial port.
Is it normal behaviour in recent versions of android for the device to recognise an otg cable as a power source? Even with no other device connected? Are there any known issues opening serial ports on the g6? (7.0)
The cable works as intended when I plug a mouse or keyboard in but refuses to open a serial connection when my takget device is plugged in. It recognises it as a HID an can pull the serial number etc.
The android serial library should not require root or any other hackery So I'm a bit confused. I've ordered a few other otg adapters just in case.
Anyone who knows what might be going on pleas pitch in.
I've had some issues getting a serial adaptor working as well. I'm on 870DS. Originally tried the wired version of this:
https://forum.xda-developers.com/an...odemu-connect-android-to-30pin-t3234840/page1
Thank God the developer changed to Bluetooth. I tried about 6 different otg cables. Worked fine on other non usb-c phones.
I suspect it is the adapter too...sucks so bad. The annoying thing is that I was so confident in android serial that I wrote a lot of code before I bothered testing the concept lol.
Does your OTG work on memory sticks OK? I have a G6 h870ds. My OTG only works for me with USB3 OTG adapters and USB3 memory sticks. I don't have a USB3 HID device to try. I now have a large collection of different OTG adapters and memory sticks. I opened up some of the adapters to buzz them through to make sure they were made correctly. They were! It took a while for the penny to drop why some things worked and some didn't!
I cant use USB2 OTG adapters or USB2 memory sticks, keyboards or cameras. Initial connection of the USB2 OTG adapter is recognized but no connected devices are detected. I used an app called USB Device Info that can give me details of detected devices and only USB3 devices are ever 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 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 and upgraded to Oreo too but alas that didn't help.
A friend of mine has a G6 H870S and all my adapters and memory stick combinations work fine on his phone so I find myself wondering if I'm just unlucky or whether the dual sim version is subtly different in some way.
I fully admit I know nothing about the inner workings of USB but as far as I can determine USB3 uses all of the USB2 connections and the additional connections only available on a USB3 port so the hardware should be OK. I'm guessing most HID devices are USB2 but if its a USB3 could you possible have a related problem but in reverse?
Every time I plug in any USB OTG adapter I get that same pop up screen that defaults to select as "power supply" even with no device connected whatever I have previously chosen.
What works for me is to plug in the OTG adapter, and only then plug in the memory stick to it. Otherwise I get the "Power supply" thing too.

Leaving just the OTG adapter connected for a few seconds then attaching the usb device does not help. USB2 devices are never detected but all my various USB3 memory sticks work reliably when using a USB3 spec adapter. I've given up worrying about it now and accepted that there is just something a bit iffy about my G6.
