I've tried a couple of different micro usb OTG cables (from my Note 4) with the usb-c adapter I use with one of my chargers but I can't connect. The menu comes up asking what I want to do with the USB, I've tried MTP once or setting it as always but still nothing. With an NTFS pendrive it came up that the drive was faulty and I needed to reformat, so I figured, ok, it's not gonna work with the drive formatted in that way. But I then tried the micro sd card that was formerly in my V20 and is still formatted to FAT32 and all that happens is it connects and then ejects the drive. When I look on ES File Explorer, a drive shows up but I can't access it. The usb message continually comes up, moments after whatever I select.
I've tried reading up on this issue and the first thing people suggest is to change the otg cable (or go for a dedicated usb-c) but I've rarely seen that as a solution for this issue.
My H910 is fully stock, no root and running nougat.

I have already read through 40+ pages of verygreen's thread and purchased the microUSB to USB Female adapter he mentioned (bought the one he posted a link to) and yet i for the life of me cannot get my nook color to recognize any usb devices. I have the latest version of Nook Tweaks (1.4.3) and i have CM7 nightly 7-30-2011 which i was told already has the kernel required to enable usb host.
I have tried every combination possible using 5 different usb drives, 2 different usb keyboards, and a charged and uncharged usb hub but no luck. I am continually pressing refresh under the usb host settings in Nook Tweaks but the folder named usbdisk remains empty. Any help would be greatly appreciated.
Try the following in this order, set up your hub with the device you want to connect, get your cables set up to connect to the nook (do not connect yet), to to nook tweeness and turn on USB hosting, now connect the cable to the nook. Wait and allow the nook to detect the device (you should see a nook tweek icon in the messenger tray. Now go to root explorer and go to /mnt, then go to /usbdisk. You should be able to access flash drives or SD cards there.

@OP,
I don't remember who but most likely Moshe, had told us that you need a powered USB hub to work with. USB thumbdrive alone, may NOT work.
Some flash drives may work through an unpowered hub but I have found that a powered hub works best. I have found that the trick for me is to set everything up first and turn on host mode before I connect the cable to the nook. As soon as I connect the cable, the flash drive lights up and the nook checks the disk for errors then mounts it. Then use root explorer to go to /mnt and go to /usbdisk iff you have mounted the device, you will be able to perform operations there. Always ensure you go to mounts and storage and unmount the drive before you remove it. Doing otherwise can result in damage to the file system on the disk and make the contents unreadable.
Feel to PM me if you have any problems or issues I can help you with. The process is not too difficult but there are a few quirks to the system.

I did a wipe and flashed the latest nightly and now some devices work. Both the charged and uncharged hub work. Only one of my usb drives worked plugged directly into the nook but all of them work when combined with the hub.

I have only found 1 flash drive (a PNY 4 GB micro) that would work plugged directly into the nook with the adapter. I believe flash drives draw too much power at least more than can be supplied thru the usb port. That is why I prefer to use a powered hub. An unpowered hub will mask the excessive power requirements at times and allow some devices to work but a powered hub provides all the power you need to use almost any usb device you can think of. The only device I have been unable to use thus far is a webcam. The nook recognizes it and assigns an device ID to the cam but the cm7 kernel does not seem to know what to do with the cam. None of the web chat programs have worked (yahoo msg, tango, fringe,ooVoo, ect.

upgrading kernel worked for me
I was running cm_encore_full-155.zip and had no luck getting an external usb disk recognized and mounted. Also, when plugging in my powered hub, everything went kinda wonky, especially the virtual keyboard in terminal emulator.
Per this thread, I tried upgrading the kernel and it started working. Hours of frustration finally gone! (upgraded to cm_encore_full-176.zip from http://download.cyanogenmod.com/?device=encore for reference)
To upgrade, I followed the instructions at http://forum.xda-developers.com/showthread.php?t=1000957
The "How to update to a new build:" section, then the part about how to boot into recovery mode (I used the "hold down the "n" button while powering on method, and the installer took care of the rest)
I've only tried with a powered hub and SD reader so far, but at least it worked. Now to find the other hardware combinations that work...
I have a rooted nexus 7 ROM:[CM10.1-20130205-Nightly], 500gb exfat external drive with lots of data, and an OTG cable. I didnt research the apps needed to see the drive after plugging it in--thought it was pnp, like the mouse, keyboard, and famous 3.5 external floppy drive setup.
At first the nexus said it saw the usb device, and a second later it gave the choice to remove the usb device. I tapped remove, as there were no other options. I continued to try reconnecting the cables, even rebooting the nexus--it would not read the drive. i installed stickmount and Paragon NTFS&HFS+ (says it supports exfat,) but no success. I decided to add a powered usb hub to the setup in case there were power issues--still no notifications.
I quickly gave up. I then tried plugging the hard drive into my pc and mac and both failed to read anything on the drive--asking me if i want to format the drive. I dont know if it was the nexus or the Western Digital piece of crap. I am wondering if the nexus wrote something to the drive making it unusable. I have tried several recovery utilities and nothing has found the data. I dont want to waste another drive. Has anyone ran into this issue, know of a way to successfully mount an exfat drive, or possibly help me recover the drive?
Appreciate any help.

Using StickMount with my N10 (stock OTA), And I've had no issues when using a flash drive with an OTG cable. However, I just got an Elago micro SD USB adapter (which is awesome!), used with the same OTG cable, but I'm having problems writing to USB storage. I've been using Solid Explorer to move / copy (neither works).
Yes, I'm rooted, and I already tried fixing permissions using RomManager. Any ideas, guys? Error screen attached.

I had a similar problem (saying permission denied even though I was rooted) with only one external harddrive I have. My others work, my sd cards in usb readers work, my stand alone flash drives work, but that one drive won't mount correctly for whatever reason. I tried formatting it with no luck.
My theory is it's some driver issue with the way that perticular drive is communicating (or not communicating, in this case) with the device.
You may be expereincing the same issue... I don't think it's a permissions issue, I think it's a hardware driver issue.
I've had some problems mounting an external HD. The problems might be different from what you're having but I've found a workaround that works for me. Hook it up to a computer and click safely remove hardware. Try again. It usually solves my problem.
Hi
Somehow when i connect a 16GB USB stick to my note 3 via an OTG cable it shows
1. USB connector connected
2. USB mass storage connected
then immediately
3. USB mass storage removed safely
so i cannot see anything from my USB device connected via an OTG cable
for instance my 16GB sandisk USB stick is not mounted anymore
it used to work with 4.3.xxx but not with the latest update of 4.4.xxx
also Air Droid can't write anymore so it's useless
my USB stick is ntfs formatted, would that be an issue?
i have Paragon exFAT, NTFS & HFS+ installed but it says it has no root access, i have the stock rom and not rooted. it used to work with 4.3 but now with 4.4 it does not work any more
thank you

NTFS will not work on android. Format your usb to exFat or fat32, or read this
http://blogs.bu.edu/mhirsch/2013/12...r-sharing-usb-flash-thumb-drives-and-usb-hdd/
actually i cannot format my flash, it's full and i don't want to loose the data
thanks anyway
Erhm copy files to PC,format stick and copy back The files?
Respect!
thanks, that would work if i'd had a computer with me. i'm away from home and was hoping i can mount my usb stick. is there a solution that does not require root access?

Not that i know of.
You can try to install the USB Host Diagnostics and check what is happening, on this app the root is optional.
i have no doubt that the USB works but the ntfs file system cannot be mounted directly by the OS so it unmounts it immediately after connection.
so my question still remains, is there a way to mount an ntfs file system without having root access?
thanks
Hi!
I have some issues with USB OTG on my phone. I have CM13 nightly from 14th February.
I connect a USB-stick with my OTG-adapter and it shows up and I can browse it. However I can't write anything to it (which is what I want to do). I have tried like ten different apps for this and the one that comes the closes is Asus File Manager. However, it closes itself if I try to copy a file over to the USB. I first had it in exFat but then I saw that may cause some trouble. I reformatted it to Fat32.
Also, it doesn't show the proper size, it should say 14.9GB but it just says 0 http://i.imgur.com/U1gro0n.png
I have tried with a WD My Passport (exFat) as well and it is just the same, can browse files and copy from it to the phone but I can't write from the phone to the harddrive/USB.
