Won't recognize USB stick - LG V20 Questions & Answers

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.

[Q] USB connection to PC not working after root

Hi,
I've got a rooted stock 4.2.1 N10 here, the USB connection to any PC is no longer working. When I plug it in the charging icon on the tablet appears but nothing else happens.
Tried different cables, different ports, different computers. Have disabled/enabled debugging options and storage type of the tablet PTM/MTP.
I'm hopeful the port on the tablet is still working as OTG cable and pen drives work fine.
Any help or suggestions our there for me?
Cheers
I have similar problem. I cannot enter to nexus from windows after rooting.
Install the right drivers.
Or it could be in a couple incredibly rare circumstances that are not at all likely, that your USB cable is broken and the data pins are able to connect. But you probably have a driver problem.

I had the same problem as you, it was impossible to make any computer to recognize the phone. Moreover it charged very slow, the phone thought that it was always plugged to the computer even if it was connected to the wall charger.
I did a factory reset, but the problem persisted. I called Google and they sent my a new phone, which now works perfect.

Samsung Galaxy S5 USB 3.0 Not connecting

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

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?

Cannot connect to pc

Whenever I plug my G5 Plus to my computer (Windows 10) the phone starts charging but I cannot see it as an external hard drive on my computer. When I slide down the notification's bar there's nothing there for me to choose from regarding usb functionality. I've tried out 4 different usb ports and the same happens all the time. Any thoughts?
Just "fixed" it. I was using a regular usb cable. When I plugged the usb cable that came with the G5 it worked. I plugged it back with a regular usb cable and the issue reappeared. Does anyone know what type of usb cable does the G5 plus come with so I can get more?

LG G6 Otg doesn't work

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.
