[Q] USB Device not recognized

Hi everybody,
I installed the drivers manually but still I get the pop up of "USB Device not recognized".
I installed the drivers named as "LGUnitedMobileDriver_S498CA21_WHQL_ML_Ver_2.1".
Help please...

Change USB port? Do not connect to fron panel USB's?

You aren't mention what version of MS Wind0w$ you're using, and what ROM you used on your phone.

And same as mgregor, don't use front panel to connect USB.

Used drivers must be obsolete. Use 3.2.1 or 3.5 and be sure android platform modem is activated to be recognized by b2c

Try LG United Mobile Driver, there is a link on knzo's CWM recovery thread. And yes try a direct port on motherboard behind your cpu case.
Also try another usb cable.

at this problem.... in my opinion is to check your usb cable or the usb port of your mobile...
if you cannot open the mobile,you can go to a mobile technician and tell him to resolder the usb port of your LG optimus....

My pc is a notebook.

Firstly thanks a lot.

I use 3.2.1 version of drivers. LG PC Suite IV or B2C can't recognize my phone.

It seems a bit risky my friend... I don't know what to do. Can I root my device without connecting to pc?? I want nova. Previously I rooted my wildfire with CM7. It was very different!

Be sure platform modem is activated in peripherals manager. This is what makes the phone being recognized by pc suite and b2c

It is activated but when I try to update driver it can not find any. Which driver should I use at that point? Maybe there is a problem in the connection point on the phone?? I am not use about taking my optimus to a mechanic.

Do you have another computer to test? Perhaps the problem was related to your Wind0w$ system...

Use WiFi, open forum and search GingerBreak, download and install it.
If your ROM are V10A, then it should work..
CMIIW.

I tried to connect my phone to an other XP result is the same "USB device not recognized". I tried Windows 7, Windows 7 did not even pop-up! Nothing happened! Only my phone was charging.
I am looking for gingerbreak but this problem is very annoying for transfering files. Each time I have to remove the SD card... Or myphoneexplorer(connected by wireless)...
Any advice?

Hi guys,
I finally managed to connect my phone to my pc. The problem was about the cables that I tried. Another original lg cable solved my problem.
But now I have an other problem. The brightness of my screen. It is usually at the minimum brightness and I can't change it. It does not change anything when I change the brightness settings. I tried other firmwares from http://luivit.altervista.org/firmwareP970/index.php but did not work still the same!
Help please...

Phone in USB Host Mode

Hello!,
I got my phone into a weird situation, every time I try to connect to my PC, it's saying "Phone is in USB host mode", the PC tries to recognizes and nothing happens, after that the phone won't charge and stays like that until I rebooted, I can charge it with the original charger after this.
My device:
HTC One AT&T 32GB
ROM: ARHD 41.0
I also tried this method with no results: http://forum.xda-developers.com/showthread.php?t=2481211
Anyone with this situation too?

You mean it's showing up as QHSUSB_DLOAD in Device Manager?
Unfortunately that would indicate a hard brick, no fix, as far as I am aware of.

Welcome to the group of unfortunate people.
I guess the best option would be to send it back for warranty repairs, mine is the same and I'm 99.99% sure it has to do with the charging port.
Unfortunately for me I'm out of the US so warranty shipping is not an option at the moment.
There are other threads about this problem, but so far the only ones I heard that solved this problem was by repair or replace.

No, it's not bricked it works ok but only charges through wall charger and if you plug it up to a pc it gets into "USB Host Mode" and then you have to reboot to be able to charge from the wall charger.

My HTC showed the same message. Saying it can not charge into host mode.
HTC only charges powered off.

Indeed man, same situation here, I'm actually in Colombia, so not an option to send it, as I can't go back to factory settings without connecting it to the PC.
@nkk71 The device is fully functional, it's just not getting detected on my pc.

What Windows version you running?
but be careful, QHSUSB_DLOAD mode is a brick... sooner or later
maybe best to get yourself an ubuntu live usb, and check adb and fastboot connections there. you can use this guide by @tobesedated to create a Live USB http://forum.xda-developers.com/showthread.php?t=2606577
maybe it's just bad/outdated windows drivers.

Steps 8-15 of my guide show how to set up adb/fastboot in Ubuntu 32bit and to check if your device is recognized. You don't have to install Ubuntu just select to try it. I think that's what scares everyone off, is thinking they have to install the OS...It seems like a lot of work but it really isn't and compared to what you've gone through, it can't hurt....good luck

Win 7 and XP are pretty much OK with any drivers & hboot & firmware/rom, but what is it exactly showing you when you say "USB Host Mode"?
Have you considered uninstalling everything with HTC.... in control panel, and installing newer version: http://forum.xda-developers.com/showthread.php?t=2089508
then see if you get MTP (Media Transfer Protocol) working again.
USB Host Mode (as in Qualcomm High Speed USB Download Mode) is NOT a good sign! it's a brick about to happen.
maybe try changing the cable you are using to your PC!!!
EDIT: and make sure you're phone's USB port is not dirty or similar

1. "Phone is in USB mode" appears as a notification on the phone when plugged to the computer.
2. Installed 3 different ROMs with the same result, uninstall everything, and nothing.
3. Don't know how to get back MTP.
4. Brick??
5. I try to charge it, but same thing happens.
6. Clean the port, and nothing.

let's take this down a notch, we dont care what your phone says, we care what shows up in Windows 7 Device Manager (or XP, maybe even Win8):
for example

I really haven't explored what steps are needed to get it back to stock, but mine connects to the pc as long as it's in bootloader so I can flash stuff like Fw but nothing that need to get into the sd card. (as far as I know).

I'm thinking this a port issue, is damage somehow, however, I hope to find a software solution.

New Firmware
Phone that was purchased was not recognized by my computer in recovery and was locked with no S-Off and did not have a Super CID, but assuming that you have all of those things already and are developing these issues then I would try updating the firmware. For some reason, after flashing the 5.11.1540.9 firmware from http://forum.xda-developers.com/showthread.php?t=2485651 and updating to ARHD 71.1 the charging issue all has seemed to disappear. If anyone wants the full run down of how I got from my original non-functioning and unrecognized phone to where it is now I can put in details, but as far as I can tell the issue is just with the firmware if you find yourself being able to intermittently charge in different scenarios when it is off.

Loading New Firmware
Also, for some reason, computer would not recognize phone with TWRP recovery yet I could push files through adb when using CWM recovery. So what happened for me was loading up CWM and pushing the files that I needed into the data folder and flashing TWRP to then install it or rebooting the phone as normal and finding the file with something like a root file explorer. I feel like I may not be very clear with this so post if there needs to be more clarification.

it's a strange issue ,i think it is a hardware problem,happen to me and i try everything possible,without success,than i charge phone when power of and it was the only way ,but led was flashing so it was intermittent charging,i was able to charge only to 97%..i use my phone and somehow next day i was able to charge phone,but then problem occur again...and wired thing is that fastboot devices list is not empty but adb devices list is empty,so phone is not fully recognized by computer,and i forgot to say that day when i was able to charge phone,adb command worked...that day i flashed firmware recovery and rom again ,because i thought it will resolve the problem...

Well i also had the same problem...but i did factory reset on the phone and flashed it to completly stock ...and since then no problem..

[Q] Very puzzling USB phone issue-please help

I have the sprint htc one m7, I have been connecting it to my PC widows 7 64bit for the past year without any issues. I have the proper drivers installed on the pc. Now when I plug in via usb I get an immediate error message= on the pc it says DEVICE DRIVER SOFTWARE NOT SUCCESSFULLY INSTALLED, on the phone it says USB HOST CABLE IS PLUGGED IN UNABLE TO CHARGE.
I think the problem is with the phone because I have tried two computers different usb ports and cables and get the same. I also tried my wife’s phone and it works as it should. She has the same phone only difference is mine is rooted (stock4.4.2) and hers is not rooted.
I have tried uninstalling the drivers and reinstalling and get the same thing.
This is really bugging me because I don’t know what changed on my phone to cause this.
Please Please help if you can. I have searched for the solution without any luck
THANKS
Doug
Quick note=Under the driver software was not successfully installed message on my pc it says MTP USB DEVICE then has a red X with DEVICE UNPLUGGED next to it?
It is however able to see the phone when i put it in Fastboot= Fastbootusb.
What the heck is going on???
another note= after plugging it into the computer and getting the errors, when i plug it in to the wall charger it will not charge. Unless i reboot it then it will charge.
Anybody got an idea?

This is probably the most drastic method to fix it but the most likely way to fix it. Flash a RUU it reverts EVERYTHING to stock and deletes everything you had in the phone.
Since the computer recongizes it in fastboot RUU will work. Make a backup and if you are S-On then you have to relock bootloader first

Thanks for the reply, i thought about RUU and will probably have to attempt it. Im just not sure if its a software or a hardware issue? Everything else on the phone seems to be working fine. It just will not show up on any computer, i have tried 3 different computers and even installed HTC sync software on one and I still get the same error message.
Does this sound like a software issue or a hardware?

What do you think?

PLEASE HElp RUU failed to fix???????
ok as stated in the OP my HTC one wont connect to my pc. The only time is connected was in fastboot, so i did an RUU to attempt to fix the problem. After a successful RUU I still have the same problem= usb debugging is on i plug it in, it says installing drivers. Then I get the red X and the error message says =HTC MTP DEVICE IS UNPLUGGED & HTC MTP DEVICE FAILED.
I know everything else is working because my wife's phone connects no problem- so its not the usb port or cable my setting are the same.
ANYBODY GOT A SOLUTION?

N900A Can't Connect To PC After Update to 5.0; Lost Root Access

I have a Note 3 which I rooted October 2015. I installed Android 5.0 using safestrap, was on 4.4.2. I had some trouble with getting 5.0 on the phone, but finally managed. Since then I don't have root access as well as no computer will recognize my phone. I have tried updating all the drivers in the world, installing them from kies, samsung website, 3rd party sites. I am convinced that I messed with something when I put 5.0 on the phone and now it no longer is talking to the computer correctly. I saw a thread that mentioned it might be the radio/modem firmware. (I can't seem to find that particular thread) I feel like I'm stuck. I can't flash the modem firmware via the computer because the computer can't see it(tried using odin/minimal adb and fastboot), and I cant flash on phone because it's not rooted. I can't root because the phone the computer doesn't recognize the phone. I've tried several one-click roots to no avail.
To summarize things tried:
Factory Reset
Attempted Root via Computer
Attempted Root via Phone(towelroot,framaroot,kingoroot)
Download any and all drivers that might work(Kies, samsung, 3rd party)
Changing the USB Settings to be AP MTP + ADB
Yelled at it
It's not my first rodeo, but I can't seem to figure this one out. Please help.

The phone does charge. It doesn't seem like it is allowing the fast charge, though.

I've tried different computers, cables and ports. That is part of the reason I narrowed it down to the phone having issues. I'm leaning toward software, but do you have any suggestions for testing the usb port?

Sorry, I don't know of any way to test the port. Replacement USB ports can be had for a low price from ebay.

Hi, firts of all sorry for my english.
My sister give to me a BLU R1 HD 2GB RAM/16 ROM, it come without Amazon ads (so i think its OEM version). Its running BLU_R001UU_V21_GENERIC.
She told me that one day just not was recognized by PC to transfer files,photos, music. I make a wipe from recovery and still the problem no USB detection at all just charging, no sounds like new USB device was conected, no device on Device Manager.( i do this on diferents PC Windows 10, Windows 8, and Linux Elementary OS , Deeping OS)
I enable Developer Options and change MTP/PTP/Only Charge option and nothing happened; I opened the device to check the pins on the USB connector and check continuity and all seem like be perfect.
I thing that may be when was update to the last software something happen and lost USB recoginition, I want to Root the device and change Recovery but i see that the steps need connect the R1 HD to PC and make some things throw ADB console.
My question is: can i downgrade the original rom from SDcard in the actual Recovery.. to try recover the USB functions. or may be its something wrong on any internal chip that no make the USB conection.

But more bad news for your plans. If you have official v21 update, then you are not rootable anyway.

I have the exact same issue... and it happened just after an OTA Update. After that it showed it was charging only when the phone was shut down.
No USB recognition whatsoever. PC/Mac. Tried several cables.... All USB modes... Factory Reset... Nothing made it work.
I contacted BLU with the issue. As soon as I have an answer (If ever) I will let you know.
If any of you know anything about this please share it here.
Oddly enough, After a cache wipe and factory reset, I have no ads on the lock screen. The app is running on the background but nothing shows up.

I think if we can downgrade to a official rom under the actual recovery maybe that fix the USB. But all methods are under USB connection to PC.

As far as I know downgrading is not possible without making the phone unusable. If by any chance that is possible maybe an update from an SD Card can work.
