I am currently having a problem with my Oneplus Device so that when I plug it in, I get a "USB Device not recognized" notification, then the device defaults to charging mode. All I am trying to do is connect my computer to my phone's hotspot, but this error is getting in my way. I had this problem a while back, but it fixed itself when I was playing around with the USB devices on my computer, and disabling them. Since the problem has returned I have not been able to replicate the fix. Through experimentation, I have been able to somewhat find the problem. By enabling USB debugging and playing around with the USB Configuration settings, I have found that my computer only shows the error on all of the options except Charging and Audio Source. As soon as I change the mode to MTP or PTP or even MIDI, I get an error. I have tried disabling, removing, uninstalling my USB devices. I have tried multiple configurations of restarting, and trying to update the drivers of the device, and nothing seems to work. Oh, and I have tried three different cables, two of which have worked in the past but the error still remains. I don't have any other computers to test this on, but I am pretty sure it is a problem with the computer, not the device.

Hey guys i have a very strange problem.
My DHD has worked since launch perfect but For some reason now when i connect my phone to PC it charges but does not give me any options for disk drive.
I have tried several USB cables (including official) and several USB ports and none of them work, i have also tried reseting the phone taking out battery sim and SD card several times , nothing works
i have also checked the setting and the notify me is ticked for USB options.
Any idea?
Try re-installing htc sync 3.0
go into cmd and type: adb devices
1 should pop up. if not, you need to install the usb drivers (Again)
Check the sdcard, I had a similar experience.
Sent from my Desire HD using XDA App
Try this:
settings >> Connect to PC >> mark "Ask Me"
You can also change the 'Default connection type' in the same screen
Hope this is your solution.
Done all this and still nothing
Just tried it another PC and it works. Still wont work in mine even though it use to. Any ideas on where to go?

Did you try all your USB-ports on your own computer? I only have one USB working on my laptop.
First I would try all the different USB ports.
If that doesn't work, the USB drivers might have been corrupted, and needs a re-install. This happened to me once, and after several hours of fidgeting and getting nowhere, a re-install of the USB drivers did the trick.
First off I have searched repeatedly and cannot find someone with the same problem as me. So if there is point me in the right direction.
My Nexus 4 won't connect to a computer via USB, it will charge, but it treats it as if it were plugged into a AC adapter. my computer also does not recognize that there is something connected to it (no errors, no trying to install drivers, and no unknown devices in computer management).
I have tried:
Multiple USB cords
Multiple Computers
Multiple OS's
Multiple ROMs (it has an unlocked bootloader from when it worked)
Does anyone have any idea what's wrong with it? Or how it could possibly be fixed?
Thanks,
Matt

i had the exact same issue and was able to get it fixed by using a usb 2 into 1 cable. like the ones that come with an external portable cd writer. once it got recognized, i wiped completely and went back to stock and locked bootloader. problem has not come back since. it was probably a bad flash that caused the issue.
once you get it going again, get it rma exchanged just in case.

Still no luck with the cable, it does not recognize that it is plugged into a computer and the computer doesn't see anything plugged in
i had same problem but my problem was on windows xp. when i try windows 8 it receognise it and than i install driver on my xp pc.
on your problem it can be because of the micro usb jack of the phone. if it gets charged it should get connected also.
I am having the same problem. My Nexus 4 used to connect to computers just fine, but now it only charges from them. Like the OP I have tried many things:
Multiple USB cables
Multiple Ports on...
Multiple PCs running...
Windows 8 and 7
Debugging On or Off
MTP or PTP
Multiple versions of CyanogenMod
Factory Data Reset
Absolutely nothing lets my N4 connect to a computer (besides charge)
When I go to Settings>More...>Tethering, the USB Tethering option is grayed out and it says "USB not connected)
If anyone has the solution, please help.
Hello all. I've got a problem with my N4 in that when I connect it to a PC via USB, the PC does not recognize any connection at all. It's not even saying "unknown device", just nothing. I've tried connecting it to multiple PC's (win 7, Win 8, Win 10) and with multiple USB cables, but I don't get anything. The only time I get something at all is if I turn on USB debugging on the N4. In this case, the PC recognised that a device has been connected, but doesn't seem to know what it is as it can't find the correct drivers to install.
This used to work fine on my Win7 machine, so I'm not sure what's changed. Anyone got any ideas what I can try to fix it?
Thanks for any help.
What I noticed before I replaced my USB port was that the port was worn out. It would charge/work with a brand new high quality cable, but wouldn't work right with an older cable.
As cables vary in quality and the data pins are different than the power pins, try cleaning the lint out of your USB port and try connecting with a brand new cable.
Just thinking out loud.
I am just going to toss this out there as one thing to check, as I know it affected me on Win8, and I think MS may have pushed out to the other versions if you did not revert the driver update yourself. http://www.eightforums.com/drivers-...usb-issue-since-last-windows-8-1-updates.html
Thanks for the link. that solved the problem. Once I set the connection to MTP. all PC's now recognise the device again. Many thanks!

Awesome, glad that worked for you. That URL is a godsend, and should be a sticky, because that USB situation will have you pulling your hair out.

Looks like the drivers in your PCs are not compatible. Get the correct drivers and try.
When some other drivers get installed, sometimes the existing drivers cease to work. I have faced this issue and solved it by installing correct drivers again.
You can also use NRT for this.
Hey guys,
I recently bought this phone second hand and started having issues. First of all I was getting the infamous 'moisture in charger port' problem which I managed to solve by cleaning the port a bit, spraying a bit of WD40 in it and putting the charger cable in with the smooth side pointing upwards (still displays error with the joined side pointing upwards).
Ok so now I can at least use the phone right? Well now I want to bootloader unlock it to root it, the problem is now whenever I connect to my laptop (Windows 10 x64) it just charges the phone and I get a popup saying 'slowly charging device, unplug to save power' but no option to change to MTP mode on drop down menu.
Anyone know how to sort this problematic device out?
Things I have tried:
Two different USB C cables, both operate fine in terms of charging multiple devices but both only work with the smooth side of the connector facing upwards
Reinstalling LG Drivers (4.2.0) from their website, cleaned installation RevoUninstaller.
Restarting the phone (initially I had tried the force stop fix on the LG app).
Disabling the moisture detector through the *#546368#*870# command (didn't work at all).
Disabling USB selective power settings through Windows power settings.
Connecting with and without USB Debugging enabled.
The fix mentioned here, exactly as its written for issues involving device descriptor failed messages, followed by a PC restart.
Tried sfc /scannow
Uninstalled drivers through device manager, restart PC and let Windows install.
Forcefully tried to use LG Drivers through manually setting it in 'Have Disk', tried all options available.
Edit:
Just found the option for forcing MTP mode on USB connection through developer options, doesn't change anything, still device descriptor failed code 43.
Edit 2:
I just noticed my cables are not certified for USB 3.0, can anyone please confirm that 3.0 is required to connect to a laptop/PC? I have ordered another cable anyway to try it but clarification before hand would be nice.
Using Windows 10. My Galaxy s8 used to work fine and I was able to use MTP and transfer files and everything. But then one day it suddenly stopped working and I'm not sure why. The only thing that works now is the USB charging. I've tried it on multiple computers and operating systems, and also multiple cables, and it still won't work.
There are no notifications that appear on my PC when I plug in my phone, and on the phone itself, when I plug it in, all that appears is a "settings: cable charging" notification in the status bar.
There used to be an "MTP" option on my phone under USB default configuration, but now all it says is "transfer files" with no mention of MTP.
I've also tried updating all drivers and stuff on my PC but I have a feeling this is a phone issue since it doesn't work with multiple computers.
Any suggestions?
Have you tried rebooting phone,
normally for data transfers you need a cable specifically for data transfer if you have the original samsung cable that it came with and try that.
Alot of the cheaper cables are charging only and will not allow you to transfer.

Is your phone charging slowly as well?
