no usb connection!

I have a problem with usb connection with PC. When i plug the cable, usb debug is active, but my pc doesn't recognize the phone...I tried to uninstall drivers and htc sync program and install them again, but still don't work..
any ideas? the only way seems to be restart tattoo with cable plugged, and pc recognize tattoo, but not always..

maybe solved, I put pc sync into taskiller ignore list. now seems to work

this usb device can perform faster if you connect it to a Hi-speed USB 2.0 port

My problem is little weird so i try to explain it as best as I can...
until today there was no problem to connect phone with USB but now when i connect the phone windows said "This device can peform faster this usb device can perform faster if you connect it to a Hi-speed USB 2.0 port. And another problem is when i turn phone into download mode start odin and connect the phone it said... usb device not recognized. I didnt flash any rom yet and i try different cables.
I am running on windows 7 ultimate 64-bit. I try two different PC and its look it the same problem.
But the weird part is that on third PC which has also win 7 ult 64-bit it works just fine.
So i try reinstall operation system but the same problem. The computer is max 3 years old so its has for sure usb 2.0
So i am little desperate because i am not sure if its problem with computers or with the phone.
Thank you for any advice!

I always had this problem with the i9100 actually, I blame crappy usb drivers.

Kies installed? Did you also try different usb ports? Chipset and USB Drivers of mainboard installed?

yes kies installed and also try back and front usb... but same result...
and usb drivers are installed manually by windows as far as i know... or?

Standard Windows message for USB connections just means what it says .
And another problem is when i turn phone into download mode start odin and connect the phone it said... usb device not recognized.
Download mode how and whats on the phone in download window
Connection must be to a mainboard usb port .
If your PC has Kies make sure its not running make sure USB debugging is off on phone .
Power phone off restart start Kies connect phone does Kies see phone .
If yes turn Kies off remove cable connect phone in USB mass storage mode wait for windows to install drivers . Does PC see phone in Windows Explorer .

yes windows explorer works
and kies also but still in usb 1.0 mode...
as I said I tried back usb and also front usb... same problem...
debugging is also off...
I try a little experiment... removed external grahics card and plug graphics on mainboard... and for a few seconds its works!
I try copy some video and speed was usb 2.0 but after few seconds its get error cannot copy bla bla and windows popup : this device can run faster and it change back to USB 1... weird...
and also i try again downloading mode but the same error... usb device not recognized...

Have you always used the same USB-port?
On some pc's, they only have one or two high speed ports and the other ones are "slow".
So yeah, try an other USB port on your pc
Sent from my GT-I9100 using XDA App

OP, I am confident it is a problem with your PC, and this XDA forum won't be able to help.
Try using another USB 2 device (like an MP3 player), see if you get the same message.
Use a different computers with the SGS2, see if you get the same message.

Thats your PC port USB 1

USB port not getting enough power .
Its PC not the phone explore sees phone and Kies sees phone = USB drivers ok
USB ports are not all usb 2 check your manual .
You can try factory reset on phone this will wipe all data .

JIAYU S3 - Windows 7 64b drivers?!? WTF HOW?????

This is about the hardest phone i got to install some windows drivers! This piece of **** drives me nuts!!
I'm about 5 secs away from smashing it onto my desk and trow it out of the window!!
Damm...
For about 2 weeks or so it worked just fine, i could connect usb to my pc and access all my files. Internal as external sd.
Now i just can't anymore... made a bunch of pictures today and wanted to transferr them to my desktop. NOPE!
When i open explorer and browse to my phone it shows 2 or three maps and then the green progress bar coms up and
the **** hangs! It takes about an hour (if i let is go on) to find some more maps.. but very slooooooooooow!
If i click on a map nothing happens... internal as external can't acces... everytime i try i see 2 or 3 maps and then the **** hangs.
Tried to restart pc serveral times, makes no difference
Tried delete S3 in device manager and reinstall, makes no difference
Tried to install a bunch of other usb drivers, makes no difference except that my pc did not like that at a certain point
Tried to uninstall all the usb drivers and restart desktop, hopefully do it with a clean install, makes no difference
I just don't know what to do, or what driver to install!?! I came from a samsung and that was sooooooo easy to install..
Plug it in, install drivers, root, flash and ****.
Jiayu... NOOO!! Preloader, ADB driver, MTK driver MTP driver... arrrgh... WTF!?!
HELP!!!!

do you have USB debugging ON (Developer options) ? If so, perhaps try with USB debugging OFF.

I really don't see whats the problem with drivers
Using, Win7 i've been using the same mtk drivers for the past 2+ years
Disable UAC, check firewall, etc

Your problem is that you never installed the driver package properly.
Anyway. When i remember right you have Win7.
Download the All MTK USB Driver_.9.2+PDanet+Adb Installer.
Go to folder Universal Android USB Driver and install
UniversalAdbDriverSetup6.msi.
This will give full access to phone memory and SD.

you should be able to access MTP or USB storage without the drivers if you previously used MTP on your Samsung phone. i have found installing MTK drivers fairly easy, be it on windows 7,8 or 10. BTW what ROM are you using?

@Dior DNA
Yes, tried it on and off, same result. Even tried mass storage or media-device..
@superdragonpt
I'm on admin account. Why firewall check? If i access usb it doesn't go trough firewall..
It did work before, and nothing realy changed.
@1testi
I downloaden loads of packages and tried them all. The one you named i just installed again and the first attempt to
browse external sd worked! So i tried internal sd and the same as before.. shows about 4 maps and then the green
progress bar slowly loading.... takes about forever! When i try entering a map my explorer hangs and does not react
anymore. Tried external sd again and shows all maps, but when i click on any of them the green loading bar appears..
@adilrenzu
I use TF Extreme ROM with lolipop 5.1

And now it even conflicts with my mouse... after a while on usb suddenly i hear the disconnect sound and my mouse is not moving anymore. When i unplug my phone, the mouse is working after a few seconds. And i see an Unknown Device in devicemanager with exclamation mark.

Most probably ROM issue.

lol.....throw away that phone :v kidding xD Try backing up data then factory reset or reinstall a rom or use a different one. If that does not work. Reinstall win 7.

Do you have USB3 ports on that pc?

Yes i have..

Most probably a cable problem. Dont use the Jiayu cable !!

Win 7 needs USB-3.0-Host-Controller-Driver. Did you installed them?

I use the white cable probably from Jiayu, but when i first had the phone i used another cable and that gave me troubles installing the drivers. So i used the white one and then the device was reconized and i could install drivers. I just ordered a proffesional platina cable, so i hope thats the problem! But i don't think so, because my Samsung Tab 4 works like a charme on that cable, so why not my Jiayu?
USB 3.0 installed correctly, see attachemend.

Something is blocking the driver during installation, that´s why you have the unknown device. Go to the "software" section and delete everything from former installations, eg ADB.
This is from a Win7 Ultimate, only with Universaladbdriver for access to phone and sd memory. The S3 is there as full_h560!

When the phone WAS working a few days ago, there was a "S3" under portable device. I guess thats the same as full_h560?
And under "YunOS" there was an ADB device, but the YunOS is gone now and i can't get it back??

Jap its the same. S3 or full_h560 or... depends on the driver you are using.
Back to your screenshot. Was the S3 switched off or on when you took it? I dont understand it. The preloader/Media Tek
driver should be only visible with switched off S3. The unknown device in the USB section is the S3 without driver. That
should be visible only with switched on S3. In your screenshot there are both at the same time...very strange.
I´m running out of ideas. As said, try to delete everything related to S3 and Drivers, ADB and PDA drivers and install them
again.
The YunOS was in the device manager of a Win 8.1 machine with optional Windows Update package Ayun.

The S3 was on. Those mediatek drivers i installed when my phone was bricked 3 weeks ago.
But that did not matter last week wen the phone was still working..
BUT... today the new cable came in and i just tried it. Works like a charme!! It was never this quick before!? :laugh:
So a good quality cable does a lot!!
Thanx again for the ideas!

Windows 10 Not Finding My Phone

Hello, I am having a rather strange problem. My PC did the dreaded auto upgrade to windows 10 the other day and I also got a new Nexus 6P. It seems my computer won't recognize my phone, at all, when I plug it in via USB. It's not even showing up in the device manager as a problem, it's like nothing happens at all.
I have
- downloaded and installed the latest google usb driver (right click install)
- downloaded the latest mtp drivers
- downloaded official nexus package from Huawei
- installed ADB and android SDK and also reinstalled the drivers from the SDK manager.
- downloaded some update for windows media player as someone mentioned that could be the problem
- tried different cables
- tried different ports (usb 3 too)
I am really at a loss. My work computer works just fine with it so I know the phone and the cable are okay and other things work on those ports on my home computer. By the way the computer is Windows 10 pro - 64bit

Have you installed Google USB Driver for nexus 6p? If not, download Google USB Driver, extract it and save it in your any name folder that you can locate it later, plug n6p in your pc or laptop and it should pop up with USB option to select either file transfer or picture transfer, click one of them, Windows should be able to find n6p driver, if not, go to setting on your pc, device manager, then look at highlighted USB of your nexus 6p whether it is properly installed, if not, then install it by finding the driver that you extracted in that specific folder... Hoping this works for you.

Thanks for the response, but yea I already got the new usb drivers and installed them via right click install. The thing is though that in device manager the phone doesnt show up, at all, not even as a problem device. Its like its not there. The phone shows that its charging, but it doesn't recognize that its plugged into a usb port. Im really unsure what to do about this.

Did you install x64 driver from Google USB Driver? Check to see to make sure your USB android debugging is checked. It is kind of odd, try to reboot your pc and nexus 6p, then plug your phone in different USB port if your pc has extra USB port..

Should be on top of the folder that your extracted...​

Ah I see what you are referring to. Well, here is the thing, how do I install those drivers? Remember I cant find it device manager to update the drivers. The only way I could find to install them was to right click the android_winusb.inf file and choose install. It said it installed okay, but of course its not working. Any idea?

By the way, I also have usb debugging on and usb configuration WAS set to MTP, but I just changed it to try the different variations, but now its stuck on charging and wont change to MTP, but I think its because the phone isnt being recognized by the computer because this morning at the office I was able to change the usb type to mtp and the others, but that computer recognized the phone... AGHHHH WTF

By the way, if your Android debugging on or check? Just turn "developer options" on your phone and then check Android Debugging. To install x64 USB Driver, on your pc, control panel, device Manager, look for phone USB Driver to see it has some kind of yellow triangle, if so update x64 driver from your extracted folder...

Hey Lucky, I really appreciate you helping me out here, but just so you know I am no newb with this kinda stuff. I have went through this process on a couple other computers with no problem, so when I say its not showing up in device manager I mean its literally not there. Its not there and just under some other name or with a problem icon, its literally not in the device list. Also, I do have usb debugging on

Please go to YouTube and type "install usb driver on nexus 6p" search and then follow instructions from the video... Good luck.

WAIT! I got it... Wow I would of never thought this, but apprently my Wacom was the problem. As soon as I unplogged my wacom tablet the phone picked right up... Strange... Anyways, case closed... freaking conflicts!

Okay hold on, still having problems. Well, now the computer dings when I plug it in, but it still doesnt show up. However when I change the phone usb to PTP the phone becomes visible on the pc in windows explorer (but still not in device manager) and when I put it to MTP it disconnects and I cant see it in windows explorer anymore, and still cant find it in device manager... Ugh...

Okay sorry for all the messages, but i did get the MTP working. I had to uninstall the reinstall the drivers a couple times... very strange, but whatever its working... yay!

Did you figure out the problem? I'm having the exact same problem with mine and with USB mode not switching from Charging and the PC not even recognizing a USB device was plugged in.

I found using a different cable solved my problem. Don't really know why cause the first one I used seemed fine and worked to charge it, but by using a different one, Win 10 recognized it and got me in the game.

OP6T computer connection

When I plug my 6T into the computer (runs windows 10) it comes up what to do with OnePlus device. I install the drivers and nothing happens. I've uninstalled all possible drivers connected to the device and reinstalled, I've installed drivers from various sources but nothing is working.
I can't access the storage on my device from the computer and click and drag from the phone to the computer and vice versa. I've went into developer options and clicked file transfer as well but every time I connect to the computer it just prompts me to install drivers which never work.
Any help will be great thanks.
