USB OTG keeps ejecting

Hello, anybody here with an Idol 3 that keeps ejecting flash drives plugged into the micro usb using a USB OTG cable? I have used 2 flash drives and 3 OTG cables and it still keeps on ejecting by itself. Thanks.
Are those flash drives within spec? If they draw more than 500 mA @ 5V, then they are NOT in spec and hence why the drives keep dropping out. Typically that means a USB 2.0 drive should be used. Or a OTG USB drive (I have one) since those have to be in spec otherwise their OTG usefulness goes out the window).
The same flash drives and otg cables worked with all my other phones so I don't think there's any problem with them. I ended up returning the phone since I was also having problems with crappy photos in low light. I have a zenfone 2 which is pretty comparable to this phone and the photos are better in low light plus no noticeable lag unlike with the idol 3. The only thing I really liked with the idol 3 were the stereo speakers which I'm missing right now.
I dont think this phones kernel supports otg. Says USB host diagnostics. BUELLER?
I tried otg also, in 9 of 10 cases, phone reject usb, in one case connections was achieved, and i can copy files from usb. But, even in that case, after some time, connection brakes. Annoying.
5.5 idol 3 android 5.0.2 .. I have used this phones OTG with flash drive, copy move paste all work and other usb devices also work.

OTG USB mounts, then immediately unmounts virtually every time

Based on similar threads it would seem I'm not alone.
I've tried a Transcend USB 3 SD card reader; although 3.0, it works flawlessly on LG G Pad running KK so not a power draw issue; I've tried an OLD 512MB USB thumb drive to be sure, same; I've tried two different OTG cables (admittedly same cord brand purchased together, but again flawless on gPad).
Mount --> Unmount.
Do many of us just have OTG dud Idol 3s? It's always been this way. Wonder if Alcatel would give me a RMA, seems unlikely. :/

Samsung T3

The Samsung T3 external SSD is USB type C and is extremely fast. Using the stock cord that came with my phone I can make a twrp backup faster than to the internal storage.
Anyone else use one?

That's because your phone has to read and write from flash at the same time. My OTG cable and USB 3.0 drive i've had for 2 years os still faster than backing up internally also. But I agree, the T3 would probably super tots.
The T3 is also very fast with the computer. Transfers 5gb in seconds

I've tried hooking up my otg micro USB cable with flash drive. But 6p isn't reading. I figured it can't transmit data micro USB style. Is that why its not reading it? Have you tried that @Gytole?

I used micro usb otg cable, then micro USB to type c adapter, into 6p. Im saying I used a type c adapter and I think that's why it wasn't connecting to the flash drive but either way whatever happened it was not connecting and I tried numerous times I even tried apps like stickmount
Whether the nexus 6p works with exfat or NTFS formatted drive
Please confirm
3rd party app will mount exFAT-formatted T3

I just took another pass at getting my 6P to work with my exFAT-formatted T3, and this time around (Android 7.1.2) saw multiple paths to success.
Firstly, this time, when I plugged in my device, the system presented a notification, which led to a dialog asking if I wanted to "format the device for mobile data storage" – which would have meant reformatting to FAT32. Not what I wanted, but pretty cool that it was an option and I didn't have to go digging.
Secondly, a quick googling turned up a third-party app that will mount exFAT volumes. It's called Paragon exFAT/NTSF (I don't have permission to post urls here yet). I had to pay $5 for exFAT support, and it wanted Total Commander (free) to browse and operate on the files.

Can't use OTG-USB in TWRP on Grouper

Hello, I've flashed a couple of ROMs on a Nexus 7 (2012 - Grouper), using TWRP and a USB memory.
Now, when I tried to flash a new ROM, the USB OTG is no longer recognized.
I've tried two different OTG cables and a couple of double ended USB sticks, but they are not recognized.
I've also tried ADB sideload, but that didn't work either.
I've had a similar problem on other devices, so I just put the ROM on an SD card. But the Grouper doesn't have a slot for an SD card.
The same thing happened last week, but the OTG came back after navigating around in TWRP. Now it seems to have permanently gone.
Any ideas anyone?
Thanks
I'm wondering whether this could be a hardware fault, possibly due to using a faulty USB adapter some time in the pas.
Is it possible that a faulty adapter could produce a hardware fault in the tablet?
In that case, is there any way of getting a new ROM onto the tablet memory and so give the tablet (my wife's) a new lease of life? TWRP is working, but that's all. Maybe jumper leads onto the USB connector. That could work if it's just the connetor, not a softare prob. I don't suppose anyone's tried that.

otg adapters can you install apps too them?

So i need too upgrade my htc droid dna cause of a battery problem which you need too take everything apart too get too it... So i was looking at a used s6. Than i found out it doeisnt have a sd slot like the dna...
Than i saw the otg sd and usb adapters and i was wondering can you install apps too it instead of the internal?
