Guys I have an S8 and I connected a USB Hub to it via OTG. It worked fine when I plugged a flash drive in it and a joystick. The next day, i tried the same thing but my phone couldn't read anything. It seems to give power, but I think is broken. Does any of you know how to fix it?

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.

I was writing some dodgy instructions from memory when I found this:

Hope it helps.
So I bought one of those cheap (sub $1) OTG adapters from Amazon, and up until today it worked. I was able to import photos from my digital camera and use a USB mouse. Today I can't get it to work at all. Not the mouse, not the camera, not anything else.
Regular USB (charging and PTP mode, I would have tested MTP as well, but it's not compatable with my laptop) works fine. I'm able to transfer files to and from the tablet, and it charges fine.
Is something wrong with the OTG cable or my tablet? Will I have to buy a new OTG cable to test?
If its only <$1 just get another one or two! Sounds like a cable problem if everything else is working
Christmas is coming, I see the shadows of Ebeneezer Scrooge !!
Are you using stick mount to load the OTG onto the N10? If so thats probably why. When i first installed my stickmount it worked but wouldn't see any of the files on the USB drive. Now after i've unlocked and rooted the device it won't even show the usb drive attached. I switched to Nexus media importer and it works fine, but i believe stickmount is having issues with 4.2.
However if the OTG cables did cost you less than a buck replacing them may be the solution too.
I installed it in my dash and removing it is a pita it was working perfectly fine but for some reason it wasnt showings charge or turning off or on with the car it just stays on i tried restart nothing happens i tried unplugging usb from powergen and plugging back in no result
Also if i go to usb rom under fixed installation i am able to check box and uncheck also did nothing
I am using nexus 7, timurs usb rom, otg cable, original charging cable and powergen usb charger
Please help thanks
Anyone???
I'm also using Timur's kernel with USB ROM for my car installation. I know that it can be very picky on the order the USB plugs are added (data and power). It may seem simple but remove the the OTG cable from the tablet and remove both the data and power legs from the OTG as well. The follow the order listed by Timur on his website:
To activate charging, you must first connect your external power supply to your OTG Y-adapter - then plug the OTG adapter into your Nexus 7 - and then connect any slave devices.

Hopefully that should get you back up and working. I completely understand how frustrating it is to have everything plugged in and see that tablet isn't charging, especially when its difficult to get to the Nexus itself.
does anyone have a easy charging solution these car chargers dont work
and a good otg y cable
You could try using a power inverter which will give you a standard US plug from the cigarette lighter. From here, you could plug in a regular outlet adapter. I found this to work pretty well with my own set up and managed to get one pretty cheap at Walmart. As for a good OTG y cable, your best bet is probably to go on Amazon and find one with a lot of good reviews. They can vary in quality and some of the cheap ones I've gotten from China have flaked out after a short time and little use.

Not seeing usb power
I had the same issue. I was using a 90 degree adapter into an OTG cable and my n7 wouldn't go into fixed install mode. Turns out my adapter cable was stopping the n7 from recognizing power. I removed the 90 degree adapter and plugged straight to otg and it worked as advertised. The issue was found during my bench testing on a 12v powersupply. I still have to find a 90 degree otg cable that will work.
So... try a different cable or if you have an adapter between the otg y cable, that may be the issue.
I can connect my V20 to a Windows PC via USB cable, and transfer files back and forth. I had to pick something on a menu the first time I plugged in the phone.
However, if I plug a USB stick directly into the V20, it does not recognize it, or respond at all. My friend plugs the same USB stick into his V10 and an app pops up and shows the folders.
I'm using a micro-USB to USB-C adapter on the stick to plug into the V20. I know the adapter works, because I tested it when connecting to the PC.
I have searched settings for "USB" and it only comes up with USB tethering.
This is an AT&T stock phone, using the stock launcher. No root or anything.
Any idea how to get the USB recognized on the V20? Thanks.
it might be that the USB host function doesn't work with those adapters. have you tried plugging in a USBC to USB adapter and plugging a flash drive into that?

I've tried the same thing without success. My note 3 & 4 worked fine. I also had a Note 7 and Nexus 6P and it didn't work with those either.
has there been any advancement on this issue?
Did anyone find the answer to this? My V20 used to boot up a USB stick but just stopped working one day.
Hello fellow OnePlus 5 owners,
One of the features I was looking forward to the most on my new phone is USB-C, since I always hated that to use any USB device on my previous phone I had to drain my battery. I purchased the Ableconn USBC-4APD USB-C hub from Amazon with pass-through power but I am having problems.
When I try to connect the hub, the phone only recognizes power and shows it's charging less than one in a dozen times, and if I then try to connect any USB device (USB flash drive, keyboard) the LED's on the peripheral just flash once and nothing else happens.
I have tried the same flash drive and keyboard with a regular OTG cable and they work fine. I had a co-worker with a Pixel phone try the hub and it passed through power every time (I did not have a flash drive along to test), it also works as a hub on my laptop (did not try passing through power on that).
My question is, has anyone else tried a USB-C hub, and did it work? Is there something wrong with the OnePlus 5 (hardware/software) in general or something wrong with mine in particular, or is there something wrong with the hub?
I'd appreciate any help in figuring this out.
Is the USB-C cable from the OP5 to the hub an USB-C OTG cable? If not, I suspect that is your issue especially as you indicated the OP5 is recognizing the input to be at least a trickle charge. To my understanding any data access and it would be restricted to read only, requires an OTG cable and the OOS OTG setting to be toggled to on (Settings->Advanced->OTG storage). If you gave TWRP recovery installed you can also check the OTG capability by mounting OTG in the Mount menu as a test access alternative to within OOS.

You misunderstand, the USB-C hub does not require a cable to interface with the phone since it has a USB-C cable attached. I didn't indicate that it at least trickle charges, I said that it rarely recognizes getting charged, as in there is no charging indicator on my phone most of the time.
The OTG setting for storage was enabled, however based on you mentioning the switch I disabled it, and it actually detects power every time I plug the hub in to it with OTG storage set to off. This gives me hope that it's a software issue and can be fixed with either patches in the future, or more likely a custom ROM. I was planning on installing TWRP once Lineage OS is available, but I may try it sooner just to give this a try.
Thank you for the reply!
