Use a shorter USB Cable.

Or try another USB port. Back panel USB ports may work better than front panel ports.

You will never know if you don't try.
Anyway, another idea: try to reinstall the drivers.

Have you checked in "active sync" on the connections tab that the "allow usb connections" box is ticked? If so then get a magnifiying glass and check the connections are ok you did.

yes mate i have done that.
That can mean just one thing - your USB is improperly connected to the board.

Hi enigma,
You beat me to it, I was about to say that the socket and /or pcb tracks may be damaged under the socket.

phone won't connect to windows 7

Hey,
Just bought a (used) One S. Trying to go through the process of root/unlock but hit a snag very early on.
The phone will not connect to my computer. I plug in the cord to the computer, then the other end to the phone. It just keeps connecting and disconnecting. Windows 7 recognised thephone as the One S before d/cing
I have tried front and rear usb ports on my computer. I have tried usb 3 ports, i have tried my usb/esata combo ports. Same damn thing.
I factory reset the phone, no luck. I have installed sdk manager. Phone charges normally. EDIT: Phone currently DOES NOT have SIM card inserted.
Any more info needed? Just ask.
Have you tried a different cable?
Or installing the drivers.

Since he described the error as "constant connect/disconnect" the drivers wont help.
It indicates that something is wrong with the connection between the PC and device, such as faulty cable, faulty USB port etc.

Thanks for your help. Drivers were installed. I guess it turns out the usb port on the phone is a bit finicky. I have to plug the cord and secure it on just the right angle or it will not stay connected. Thanks for all the suggestions!!! Now i have a new problem....BUSYBOX will not install feel free to hop over to that thread if you are feeling EXTRA helpful today

s8+ not connecting to pc via sync cable

Recently had to get my S8+ changed through insurance and now every time i plug it into my win10 PC it isn't recognized. it will charge from the PC but will not display in the my computer section as a device. I've tried a new cable various USB ports turned on USB debugging and downloading drivers. ive also downloaded the smart switch app to PC but it doesn't recognize it either.
any ideas would be much appreciated
thanks

Have you tried to change the the "usb mtp" from notification area?
Change it to "File Transfer" or "Picture" to force PC connection.

Doesn't give me the option when plugged into pc. The notification area just displays the charging message. When I press on it it takes me tothe battery settings of device maintenance

Sounds like you're using a power-only cable. Might try other USB cables, especially the one the phone came with.

I used the original cable and purchased anew cable but I believe it may not be an official Samsung one I will have to try a new cable and see

Could also be the PC is not recognizing as a USB device. I forget how to get Win10 to start looking for USB devices again, but recommend you Google variants of "windows 10 does not recognize my USB device". (Shortest: "windows 10" and USB and autodetect")
I fixed this once, forget how.

Of coarse I am going to ask all the same obvious stuff So you have tried different cables have you tried to make sure there is no trach in the usb type c ends? Also try booting to safe mode and a factory reset of coarse back up with sammy cloud first it does good about restoring most stuff.....
Only other things is drivers again and try other usb ports as well as a different PC.
My be defective device also
By chance does anything come up in device manager?

I would contact the insurance company and let them know they sent you a defective one Sounds like you have tried just about everything

That could also be if the S8+ has its USB setting to be (for example) Power only.

PC not recognizing my phone thru usb

I recently bought a Google Pixel it's all working fine
But when I plug it on my PC it doesn't get recognized even though the phone is charging I don't get any notification that the phone is plugged through USB I have all the drivers installed
Here are the errors I'm getting: "Unknown USB Device (Device Descriptor Request Failed)" and "Windows has stopped this device because it has reported problems. (Code 43)" please help I've moved from iOS recently I don't want to refund I freaking love this phone! and i'm starting to get desperate.
Thanks
Not for the Pixel 2 but I thought it'd be the same case plus I need help ASAP cause I'm leaving country soon!
Are you connecting it using the cable that it came with? If you are, try a different port or reboot your phone and see if that helps. You can also get into the developer settings and tell it to MTP rather than USB Charging. Sometimes that helps. You can also try different cables, (if desktop) use the usb ports on the back of the computer rather than the front.

Yeah I did it all. It just doesn't wanna work
The cable it comes with is garbage. Use that only for charging and go buy a good USB C or USB A to C cable (for transfer, adb, etc. I've had better luck with the A to C cables).

Make sure you are plugging into a USB 2.0 port. If all you have are 3.X ports you need to enable USB debugging in Developer options. If you are plugging into a desktop use the ports on the back of the machine.

It's too late for that now mate
I don't bother connecting with a cable. I use the free app 'Airdroid'. It gives you a url to use on your computer and as long as both your phone and computer are on the same network you can see all your files, photos, messages etc. on your computer screen. Very easy to move files either way and do all sorts of other things. Very slick.
BTW, you don't need to setup an Airdroid account just skip that bit.

Nah I'm doing this so I can root n stuff
You don't need pc to recognize device as a drive via USB for file recognition to root and stuff. Just use adb push and pull. That's of course if it is recognized by adb. Mine is that way as not recognize mtp drivers but adb is fine

I had the same issue when I first got my phone. Initially, the only way I was able to get it to work was plugging directly into a USB port on the PC....it wouldn't work on any USB hub. I ordered a Anker Powerline II cable (my hub was Anker so I figured it would have the best luck) and it worked. No other cable would work...not sure why. Also, I didn't have to enable debugging (I had tried that before and it still didn't work)...I was able to go into Settings and change USB from charge only to file transfer.

I've had the same issue - it ended up being a bad cable.
I know you probably checked this, but... did you update the Google drivers on your PC? My phone wan't recognized until I installed the latest from Google.
Just use an a to c cable. If you're using the adapter that came with your pixel, it won't work. And yeah everyone else is right, use the 2.0 port
Apparently 8.1 fcuked up usb 3.x connections such that you can't even use them for data, only usb 2.0 for now, it's super annoying. There's an issue tracker for it if you want to star it.
I use Solid Explorer and the ftp server to connect to Win 10 for file transfers atm
I had the same problem. After I finally switched to my one USB 2.0 port, I was subsequently able to use my 3.0 ports again. It was a while ago, so I don't remember the details, but I think I updated the driver for the device that was reporting as active in Windows Device Manager while I was connected via the 2.0 port.

Problem with connecting Kingston USB DTDU03C via USB-C / OTG

When I leave this USB flash disk connected to phone during rebooting / switching on, everything is OK, I can see this disk in "My Files". But when I connect it simply when the phone is switched on, phone do'nt recognized it. This applies to connections both directly via USB-C and via OTG reduction to USB-A.

Yea not that long. Out of curiosity the port isn't dirty or anything is it? Only other thing I could say is maybe a firmware update

Thank you for your answer! I think USB-C port is OK, connections to USB-DAC, computer etc. are OK, also after rebooting phone with connected USB flash is disk visible everytime OK. So I will continue to look for a solution.
I have the same issue. Has anyone found a solution?
