[need help] usb device not recognized!!!

hey guys,
I don't know if this still a problem with people. but I'm on win7 64bit and I can't seem to connect my nexus s, to my computer. I always have to upload from computer to dropbox then download the file from DB on my phone... usb plug doesn't work. I tried the same cable with my wifes Samsung vibrant and it recognizes it, but when i plug in my nexus s the debug icon shows up on my phones status bar for like 1 second and disappears. then window on my compter says "USB Device Not Recognized"
need help please.

What does it say in device manager (in windows)? Maybe the driver is wrong...

do u have a right drivers installed
have a look here and check Google USB Driver

I'm having the same problem. I have tried both my computers and multiple cables but I continue to get the error. When I try to update the drivers or reinstall them Windows says the drivers are up to date. I've tried every USB port on both computers as well.
I even took the phone into a repair place to see if perhaps the USB port on the phone was malfunctioning and they couldn't find anything wrong with it.

Try installing pdanet, I had a similar issue when I rooted my ns and installing the pdanet drivers solved the problem.

I've been having the problem also and none of the fixes worked. Not even PDA net. You'd think that the more people have this problem so one would have found a real fix by now.

I can't get the PDAnet drivers to install - during the installation process, my phone has to plugged in, which of course the installation program can't see.
Weird thing is if I remove the battery and then plug the usb in and start the phone, the drivers show up in the device manager but they always disappear before I can unlock the phone - appears the USB connection on my Nexus S is broken...can;t think of anything else.

PC no longer recognizes Nexus 4: USB driver failure

Problem: USB driver failure for Nexus 4. The android composite USB driver loads. Portable device driver (MTP) does not.
I have the latest v7 Google USB drivers in the extras 4.2.2 SDK folder, and pointing the driver install to this folder has worked in the past. Now, I never get the portable device MTP to install. I have both windows 7 and windows 8 machines that used to recognize the phone. I suspect my phone USB firmware is corrupted ( or something else software related?), but don't know how to find or make a zip file I can flash via custom recovery to test my theory.
I've tried multiple USB cables, all which have worked in the past. Simultaneously, I can only charge at USB rate. This all started occurring a week ago.
Any recommendations?
LG-E960

A different Nexus 4 connects fine, mine has no response to USB. It will charge off the PC, but no adb device found, no fastboot device found, no portable device MTP. I think something is wrong with my USB firmware on the phone.

Are you sure usb fast charge is not on?

User failure in this case, install these drivers from here http://forum.xda-developers.com/showthread.php?t=1998650. Delete all excisting usb drivers and then reconnect to usb and prevent/stop windows from installing drivers. Open device manager in windows and select the N4 and install the 0.72 drivers and you`re done.

I'm having the same problem, ADB, MTP none of it works, I've tried every method including yours. Worst part of it is that nothing happens in the device manager when i plug in Nexus 4 so i can't update drivers manually too. It used to work great with both MTP, ADB etc. Stopped working all of a sudden...Help please anyone. The phone is pretty much useless without MTP or ADB for me.

I too,, have tried to clear all old drivers and use the universal driver, but nothing works. I went through the tedious windows 8 advanced startup to allow unsigned drivers.

This sucks. I still cant resolve this, and 4.3 is coming. Maybe I'll try Ubuntu.

Problem with Nexus 4
Any updates about this?
I'm going through the same thing with my Nexus 4.
No response to USB, except charging.
No ADB, No Fastboot, No MTP nothing at all, it's as if the system detects only a device that uses power from the USB port and nothing else.

It was the same with my phone. Wasn't detected on other computers too.
Here's what led to the problem resolution (kinda):
1. Formatted /system, /data, /cache, and flashed CM 10.1.2: http://get.cm/get/jenkins/34261/cm-10.1.2-mako.zip
2. Restarted the phone, then I came upon this forum post which mentioned that Trickster MOD Kernel Settings should be used to test for fast charge.
3. To install Trickster Mod I had to have Play Store (and thus the GApps package), so I rebooted into recovery.
4. After flashing the GApps package and rebooting the phone got detected and I was back in business.
5. Immediately flashed the factory image JDQ39 (it was the one I had available at the time.
6. Received the 4.3 OTA update about an hour ago and the phone is again back to not functioning on USB.
(Worth mentioning here that before this fiasco started, I was on CM 10.1.2, linked above.)
-- Update --
Rebooted a few times, phone appears on USB now and is there consistently, I'm beginning to think this is a hardware issue but I cannot apply for a warranty claim until the problem is consistent enough.

I've been having the same problem the last few weeks. I am on v4.3 stock. The phone is not being detected in any computer i've tried. I've used several USB cords and none of them work. The phone can be charged, but only in USB mode, so charging is slow, even when using AC charger.
I think this problem was triggered by charging on a cheap car charger. The Nexus 7 also can get into this state from what i've been reading.
I haven't come across a fix yet, so I think I'm going to RMA it before the warranty runs out.. its to bad though, I think this is a software problem related to 4.3. I used a lot of cheap chargers without this problem coming up before upgrading to 4.3.

Just go to storage settings and just try uncheck and re check the option of USB connection . It worked !! for me

Tried that. I also replaced the USB flexible circuit card ($25 amazon) and nothing changed. I'm glad their are people like xDA member, enfrant, that provides zip files for updating the phone, else I'd be stuck with a non- updateable nexus 4, which would be a nightmare for a flash junkie.

Very basic step but I've seen it being missed before:
- Go to Settings
- Storage
- Menu > USB computer Connection
- Check Media Device(MTP)
If this was not checked, checking it will make your computer download the necessary drivers if not present already.

[Q] Bricked Updating to CM11

Hey guys any help or suggestions will be greatly appreciated on this matter. I will try to be as detailed as possible but I'm trying to fix this phone for a friend and he isn't very phone savvy. From what I understand, he was previously on CM10 and tried updating to CM11 using the cmupdater. For some reason it failed and he was stuck in TWRP. When he tried to reboot it kept kicking him back to recovery. He took his phone to a phone repair shop who then wiped his device. At this point he gave me the phone to try to fix.
First of all I have working fastboot and adb drivers for my Nexus 5 so I don't think this is a driver issue but I'm no expert on the Nexus 4 so I could be wrong. I'm also running Windows 8.1 if this is any relevance.
I can still access the devices bootloader (ver MAKOZ20i)
I can still access TWRP (ver 2.6.0.0)
When plugging the device into my USB 2.0 ports, nothing shows up in my device manager in bootloader, TWRP, or TWRP ADB sideload.
When plugging the device into my USB 3.0 ports, I see 'Unknown USB Device (Device Descriptor Request Failed)' and the Device Instance Path is 'USB\VID_0000&PID_0002\7&20F39B9B&0&2' in bootloader, TWRP, or TWRP ADB sideload.
I've never heard of a device not being seen at all in by USB 2.0 ports but showing using USB 3.0 ports so I attempted to give extra juice to the phone using a powered USB OTG cable. Still nothing shows up.
I've tried running 'fastboot device' and 'adb devices' with no luck.
I think I've covered all the bases... can anyone think of anything that could help me re-install a new rom or factory reset or his he out of luck?

I think it may be a Win8 problem. You have access to another machine with Win7 or WinXP?

Install "universal driver.exe" in win7, than connect phone while power off, I think it'll install driver...than push any custom ROM to phone via adb or just flash any official IMG..

Well I can tell you WHY it didn't work. That version of TWRP is not able to install 4.4 (CM11). if you manage to successfully push via adb and get it started again, make sure to flash the newest version of TWRP before trying that again.

Thanks for the reply guys. I kind of guessed that the version of TWRP was not compatible as I installed CM11 on my old Nook Tablet and had to update my recovery before installing it. Unfortunately the guys who wiped the phone prevented me from installing an old version of CM10 that my friend probably had from the cmupdater.
As for Windows 8 being the issue.. I attempted to try to use my laptop which runs Windows 7 but was unable to get anything to happen. Since the laptop only had USB 2.0 ports, plugging in the device to any of the ports did the exact same thing as what it did on my desktop (Windows doesn't even recognize anything is connected). I still get the charge animation on the phone but yea... nothing in device manager. I'm thinking of running Linux from a live installation to see if anything different happens, unfortunately its been ages since I've touched Linux so this is kind of a last ditch effort here.
Any other thoughts?

One more, when you plug into usb 3.0 you can see unknown device Right ??
If yes, download driver files from here Here.
It's a zip contains .inf files, Now click on unknown device and select update drivers then give the path to these drivers manually.
Hope this will help you out.

I'm pretty convinced at this point that the phone can't be fixed by me. Running it through Ubuntu I can't see the device at all (USB 2 & 3) when running the lsusb command but it sees my nexus 5 just fine. I even tried modifying drivers to match vendor id product id and class id as reported by windows. Thanks for the suggestions. Does anyone know of a reputable service to get this phone repaired? How much does a JTAG repair usually cost?

Awesome! Didn't realize this was an option. It didn't work using the USB 3.0 ports but the USB 2.0 actually worked for this method. Thank you!

[Q] Nexus 4 gone stealth

... and is no longer recognized when connected to a computer via USB, meaning I can't return to stock to get ready for the Lollipop OTA.
Got a rooted Nexus 4 running the latest PA beta.
What happens when connecting to PC:
- On two different Windows machines: systray popup saying "USB device not recognized. The last USB device you connected to this computer malfunctioned etc.". In device manager it says "Unknown USB device (device descriptor request failed)"
- On elementary OS, based on Ubuntu 12.04: nothing, besides charging.
No USB debugging connection notification on the Nexus 4 either when plugging in.
What I've tried (USB debugging enabled, all relevant drivers installed):
- Settings > Storage > USB computer connection > check Camera PTP (used to be required in order to get an RSA key prompt when connecting to a computer, now it does nothing)
- Flashing latest stable CM to see if PA was to blame. Made no difference.
- Uninstalling device through device manager in Windows and reconnecting. No effect. Driver update doesn't work either, finds nothing.
- Using Wugfresh's Nexus toolkit to see if that worked, but that obviously doesn't work either when the device isn't recognized, same with the Universal Nexus Linux Toolkit on Linux.
- Scouring the net for solutions and coming up with nothing
I have flashed factory images before on this phone without problems. Should I consider it a hardware failure by now, or is this a known issue with a fix?

Try a new wire, different usb port on computer, finally look into cleaning your charging port on the phone/replacing it.

Tried three different cables, every port on two laptops, no joy - my girlfriend's phone connects normally.
Wouldn't replace the charging port, then I'd just get a new phone since it's a 2 years old Nexus 4. If only there was a way to flash the factory image using only TWRP.

Thanks jd1639, that seemed to be exactly what I was looking for -
- but then I had an extremely blonde moment and formatted everything in TWRP, wiping the ROM I was gonna flash in the process, on a device where USB file transfer doesn't work anymore
My phone is now a paper weight.

Have you tried the file manager in twrp yet? I've found it connects when nothing else will...

6P not recognized by any computer

I have a 6P running on android 8.1 SuperXE rom. And when i tried to run Substratum and it asked me to download the Andromeda app to make it work so I did. Then i went on my Desktop downloaded the script for that followed all the instructions. Now after running the script a couple times my phone no longer works with adb. It is not a computer problem because I have tried to plug it in on multiple computers that have the right drivers installed and none of them work. It seems to be a problem with my phone.
I have tried factory resetting my phone uninstalling and reinstalling drivers. Nothing seems to work.
Has anyone ever run into a similar situation?
Also the error that shows up is USB device not recognized, "the last USB device you connected to this computer malfunctioned and Windows does not recognize it." It says this on both my windows computers, and my Linux laptop. So I know it has nothing to do with the phone cord or the computer.

It's probably the chord try another one. And if you root your phone with magisk you won't need Andromeda and Android pay still works. I'm on SuperXe also and don't have any issues. It's pure stock with some add-ons and customization.

Check with another cable or clean flash a stock rom via fastboot to see if the issue still persists, mm,n or o, it doesn't matter.
Edit: first go to Dev options and reenable USB debbuging and set USB configuration to mtp, may a phone reboot is required.
Edit: to reset the USB debugging authorization is worth a try too.

The first time I installed 8.1 it said it required Andromeda to run, but after I wiped my phone and re installed 8.1 it worked without it. Which was weird.

I went out and got a new cord and now it is working thanks for the advice. It's weird though because nothing was wrong with the cord before this incident.
But thanks for the advice it was the cord I have a new one and no problems thus far.

Not to hijack this thread but I am having a similar issue. My nexus 6p and an old Nexus 6 will not connect to any computer. I have used different cables and still no dice. I have a Nexus 9 that connects fine. Both Nexus 6 and 6p charge on the cables but will not connect to computer. Any thoughts or suggestions. Again have tried different usb ports in same computer 3 different computers and multiple cables.

May start from scratch with the drivers, download usbdeview (simple Google search) and get rid of all nexus and or android installed drivers. Reset USB debugging and authorization on the phones, set to mtp, do a reboot and do a fresh connect.

Neither my Nexus 6p nor the 6 show up in usbdeview. Only the Nexus 9. Tried revoking. Have done factory reset set to mtp turned debugging off then on restarted phone different cables still doesn't show up in usbdeview.
Also the point of all this was to try to get this to work with my Mavic Pro drone. Which also does not recognize my 6p and thinking about this now my car also does not auto launch Android auto like it used to and in fact does not work at all. Phone charges from usb but does not seem to communicate.
Faulty phone maybe?
Is there a way to get off Oreo without having usb access? Not currently rooted and the apk's I have tried seem not to work.

It's strange that your n6 and n6p both don't communicate.
If you got TWRP installed you can root and flash what ever you want with flashfire. Or with TWRP itself. But never ever flash bootloader and radio with flashfire, it isn't necessary all the time anyway.
Or is your n6p completely stock ???
Uhh, I do miss my Nexus 6
