So this wasn't always a problem, and I can't say when it happened, but it has begun to annoy me more recently.
OTG storage used to work. Something like six months ago my Galaxy S7 Edge (Android 8.0.0, Verizon, Developer Options Enabled) stopped recognizing when I plugged OTG storage devices into the phone.
The two USB thumb drives I primarily use are:
SanDisk, 128 GB Ultra Dual USB Drive (USB 3.0 / Micro USB), formatted ExFat32
--> This is not detected when directly plugged into the micro USB on the phone, nor when connected by USB OTG cable
SanDisk, 32GB Ultra Dual USB-C Drive (USB 3.1 / USB-C), formatted Fat32
--> This I can only connect with an OTG cable, not detected
Both of the drives work on Samsung Galaxy Tab S2 and Tab S4 (I got the Tab S4 for Christmas).
The only way I can easily get files onto the S7 Edge is by connecting it by USB to a laptop.
I don't see any settings that would turn on or off OTG Storage in the settings. I don't want to reformat the drives, I've tried that many times.
Does anyone have any suggestions as to what might be keeping them from being detected? I have the pro versions of ES File Explorer and Solid Explorer both on the phone.
Thanks,
Joe
Hey Joe, I realize this is almost a year old but did you ever find a solution? I've just formatted my DUAL USB (128GB) to exFAT and it is no longer recognized by my Galaxy S7 Edge. Any hints greatly appreciated. Cheers, Scott
I have not been able to get the S7 Edge to recognize external storage / USB togo memory. I gave up trying; transfer files directly from pc to the phone now. I assumed it was a software update that killed usb memory access, but never was able to confirm.
Sorry,
Joe

Hey,
Does anyone here have the USB adapter for their Samsung Tab 10.1? Can you connect a USB hub to it (maybe a powered USB hub)?
I take lots of full resolution photos, and would like to use the Tab to transfer data from SD card to portable USB hard drive.
What I want to avoid is having to first copy the SD card contents to the Tablet, then connect the tablet to the portable HD to unload the photos. That seems like unnecessary wear/tear on the flash memory.
If the USB host on the Tab 10.1 can handle a hub, then I can connect both the SD card and portable HD at the same time...hopefully the Tab would make use of it's RAM (the 1GB spec) to transfer chunks of data at a time, without resorting to using the internal Flash memory.
Am I right about that? The Android OS doesn't use the flash memory as a page file for working memory the way desktop computers do with drives?
bump - hoping someone can answer. Thanks.
There is a thread in development about a homemade usb adapter, and it works successfully with a hub. The samsung adapter isn't available yet, but should work the same

pokey9000 figured out how to force the unit in host mode. All you need to do is put 20ohms of resistance (easiest way with two 10Ohm resisters in series) between pins 13 and 15.
He also tested using a powered hub and was able to connect to multiple items at once. A regular hub might work for a few thing that are low powered but if you plan to have two hard drives, it better be powered.
has anyone found a usb to sd card adapter for multiple sd cards?
Did you ever figure this out? I want to do the same thing.
I bought a 32gb SanDisk Cruzer Fit to store my music library on, and it worked initially with USBOTG and stickmount. However, it no longer works with Nexus 7, all other memory sticks are fine, and the SanDisk works on my PC, but not the Nexus 7. Anyway, I plugged it into a USB hub and it works again, but only through the USB hub. Anyone else noticed this kind of behavior? I'm guessing it's related to power draw, as the hub is mains powered, but I'm surprised it can't cope with a flash drive. I'm now wondering whether to buy another device, or whether the same thing will happen.
I had the something similar and a reboot fixed the issue for me. I tried plugging in my 250GB WD Passport but I guess there wasn't enough power for the external drive because it kinda just sat and clicked. I then tried plugging in my 16GB thumb drive that I know worked the day before but now matter what I did, I could not get it to mount through StickMount. I rebooted the Nexus7 and I was then able to use my thumb drive again. Not exactly the same but try a reboot if you haven't already.
I also have that problem with my Buffalo USB hard drive, where it sits and clicks, it's OK via the hub, but not direct. A reboot doesn't make any difference. I'm wondering if it's my USBOTG cable, as that's the only variable, I have read that others have got the SanDisk 32gb to work with the Nexus 7. I'll try another cable...
Got my new USBOTG cable, and the Sandisk 32gb now works. My external HDD still doesn't work (unless plugged into hub), but that's not too surprising. The new cable is this:-
Afunta(tm) USB 2.0 A Female to Micro B Male Adapter Cable (search on amazon.co.uk)
The old one works with most of my USB sticks, but is maybe not as solid in terms of build quality, as the new one is much tighter. The old cable is this:-
Brand New Micro USB Host Mode OTG Cable Flash Drive SD T-Flash Card Adapter FOR Samsung GT-i9100 i9100 Galaxy S II 2 GT-N7000 Galaxy Note (search on amazon.co.uk)
I am wondering whether anyone has connected a USB 3.0 hub to the Axon 7.
The reason I ask is that I am going on a trip soon and want to back up my camera SD card each day to a USB stick. I don't want to take a laptop. What I'd like to do is connect a USB card reader / hub to the phone to copy files from the SD card to the USB stick at USB 3 speeds. Devices like the Ravpower wd03 only do usb 2, which will take ages per file.
Will this work? Will I need a USB 3 otg?

Update - USB Hub Works - but.....
OK, so I took the plunge and bought an Aukey USB C to USB 3 adaptor and a USB hub - one of these. I did it that was as I don't have other USB C devices.
The USB hub works fine with USB memory sticks. Each time i insert it registers a new USB OTG drive and I can happily copy to and from it (and more than one
But every time I insert an SD card into the SD reader, the Axon 7 gives me an error "Unsupported USB Drive: This device doesn't support thus USB drive. Touch to set up in a supported format". When I try to format the card, it fails.
Any ideas?
Update 2
I should add that:
1. The same problem occurs even if I use the MicroSD card I use in the phone - so it is not a formatting issue.
2. I also have a Note 5. If I connect the USB hub to that via a USB OTG, the Note 5 can happily read the SD Card.
3. The SD slot USB Hub works fine when when plugged into a PC.
Do I need an additional USB OTG? Will that conflict with the phone?
Update 3!!!
This is getting ridiculous but I want it to work.
So I tried plugging a SD Card reader into the USB hub. Lo and behold it works!!!! I wonder whether the issue is just that the SD card reader in the hub is missing something which allows the Axon to read the SD card.
That was only USB 2 - I am going to invest in a USB 3 SD card reader (my camera produces large files!) So I am going to invest in a small USB card reader and will report back.
Update 4
So the card reader has arrived as has my USB 3 stick. Now I can copy all the files from the SD Card to the USB Stick.
The only issue is that Dropbox scans the cards and starts trying to upload them as Camera uploads so I've had to kill the process.
The other issue is that my file manager (File Manager HD) doesn;t allow copying and I have to use the System file Manager, which is awful. Am going to work on that process over the weekend. Any suggestions gratefully received on that front!!!
Rubbish. Rubbish. Rubbish
The connection just isn't stable enough. The phone keeps saying that the card(s) keeping g being disconnected / removed. There is nothing wrong with the hub or either the USB stick or the sync card / card reader.
Last chance - I will add a power supply to the USB hub. If that doesn't work I'm afraid my views will be confirmed - this is a great phone with a great DAC but other than that it is just a bit rubbish and cheap for a reason, with a manufacturer which doesn't want to develop for it. I'm the EU least.

Hi guys. I have bought a Patriot Stellar OTG USB 3.0 16GB flash drive. when I connect it to my Samsung S7 Edge I encounter the error that says "High-power USB device connected..." and it doesn't open. While my brother's Galaxy Note 4 has absolutely no problems opening it. I also have problems opening any USB 3.0 drives via OTG adapter or other OTG cables. Does anyone else have the same problem? Any solutions??

Can't open my 32GB Sandisk Ultra in a microUSB adapter on mine. 16GB works OK. Samsung appear to be a little excessively conservative on power allowances on the port for some unfathomable reason. This is running Nougat.
I got two S7 edge, one is ok with a samsung otg usb drive but the other is not, however, it's fine when using a otg cable. (dual connections, normal usb and otg usb drive)
same problem with my s6 edge, unable to connect to Pc
I have a LG G6 H873 and I'm trying to use an OTG adapter to read an SD card (Kodlix Type-C Reader) and I'm not getting any prompts for a USB device being detected (and the LED doesn't light up on the adapter).
I've tried the same adapter on my wife's LG G5 and it works fine (both os are at the same revision). I've also tried the "OTG Troubleshooter" app which seems to detect that a OTG device is plugged in. Plugging a USB cable from my PC to this device works fine and I can browse the files on my phone from the PC.
Any ideas?
Same here. OTG worked fine. Then one day stopped working.
My phone recognizes all my files in file folder but stock gallery and music app showes no pics or songs.When i flashed oreo update my sd card worked fine.on boot up it would show media scanning and then show a little sd card icon in the notifications but after 2 days my phone does not scan anymore.Is this related to your problem?
I have a G6 h870ds. After loads of mucking about I have discovered that my OTG only works with full USB3 OTG adapters and USB3 memory sticks.
I cant use USB2 wired OTG adapters or USB2 memory sticks. Initial connection of the USB2 OTG adapter is recognized but no connected devices are 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 the 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 but alas that didn't help!
No issues whatsoever if I plug in the OTG adapter first, then the drive. No matter if USB 1, 2 or 3 memory stick.
