Hello I have a strange problem I can not connect my p8 lite up to a computer or any laptop. It charges but does not detect for moving files over or anything else other than charging up. It detects when it wants to not when I need it to lol.
I have also tried the following
USB mass storage device
shows mounted but does not detect.
Tried new usb cable no joy
Have also gone into service menu using *#*#2846579#*#*
Then going into background services usb port settings and using manufacture mode als tried google mode and hisuite mode and still not working.
Any advise to fix and resolve this would be greatly appreciated as I need to update my phone and put new rom on but can not due to the above.

Hey all,
I have tried to google and figure this out but my phone doesn't show up in device manager in windows or in android file transfer on mac EXCEPT when in download mode or when the phone is off/charging via my computers USB port.
So when in download mode, the phone shows up in device manager....
When my device is off and charging via USB port, it shows up in device manager...
I have tried USB debugging mode no change...
Charges just fine. No usb port issues because it connects during download mode etc...
During these times, i obviously can't access the SDcard.... but as soon as the device boots, it disconnects and disappears from device manager even though its still charging etc...
This only happened after the last OTA update.
I assume i will have to restore to defaults as its probably an issue with the kernel and usb protocol but I dont have the phone rooted and i don't want to root it at this time... I am hoping there might be a quick fix and/or setting i am missing.
Thanks!

You do have to have USB debugging mode checked. If you don't have the developer option enabled in settings, go to about phone, find your build number and tap on it rapidly until it says your developer option is enabled. Back out and you should see a developer tab. Click it and make sure USB debugging is checked. If that doesn't work you might reinstall the latest USB drivers.
i did both of those. the odd part is when in download mode windows chimes that my device it attached.. no problems right? but anytime the android OS is running no chimes at all no recognition at all on any computer... its almost like back in my linux days when the kernal had a usb module failed to load... i swear its as if the kernal turned off usb data communication... power is fine... just wont communicate unless in download mode or in a power off state.... totally weird...
When you plug it into the computer, pull down your notification drawer, make sure USB setting is set to MTP. It usually is set to installer, or charge only by default.
Also I'd say completely wipe out your phone drivers on the computer, and reinstall all new ones.
Possibly reinstall ADB as well.

Hi Basically plugged my S4 i9505 in via usb. Nothing shows in my computer, but phone remains charging. I have tried uninstalling and reinstalling all samsung usb drivers but it does nothing. Tried installing kies/older usb drivers, still no luck. Regardless of if there are drivers or not on my pc, there is no detection what so ever. My pc is detecting my second S4 I9505 perfectly. Anyone know the solution to this?

Tap 5 times buildnumber in settings menu under: about phone to open developer settings. Enable USB debugging. Now you can choose what to do when phone is plugged in pc.

USB debugging is Enable still nothing happen
USB debugging is not required in order to have the phone recognized by the computer.
Have you tried different USB cables and USB ports? Is the phone detected on other computers?
i had the same problem.... and we found out that the pins or the usb connection sh1t from the phone doesn`t make good contact. si try to push a little but or force up and down the usb cable to the usb from phone maybe you will manage to find a stable connection or something.
when i connect to phone to the pc i have to hold the usb cable connected to the phone in a weird position. that works for me
Hello guys,
after trying everything I could imagine and find on the net, I still didn't get my PC to recognize my S6 edge plus.
Hopefully someone od you has got some more ideas.
The Problem:
Connected Phone shows "Unknown USB Device (Device Descriptor Request Failed)" in the device manager. No MTP connection and no ADB possible so far.
Done so far:
Samsung USB Mobile Drivers
Kies
Smart Switch (with reinstall of drivers)
6 different cables with 4 PCs (2 Win10, 1 Win7, 1 Linux)
USB-Debugging on / off
*#0808# switched through every mode
USB-Hub drivers
Factory Reset
More Info:
5 of the 6 cables are working just fine for data connection with my S3
There is no infobar tooltip to change USB mode at all, just telling me it's loading
In Download Mode the phone doesn't get recognized by Odin (with same cord and USB Port the S3 does)
In Stock Recovery Sideload Mode the Device does not show up in adb devices (with same cord and USB Port the S3 does)
Regards
up
I'm guessing you have downloaded and installed the Samsung drivers?
New Infos on this case:
Local tech support inspected the phone. They suspect the mainboard to be defective due to corrosion signs.
Of course the repair cost would be ridiculous.
I'm gonna repair it myself, but I'm not quite sure if it's really a faulty mainboard.
I rather think of changing the USB board first, because it's like a 10th of the mainboard and more likely to get wet if that's the reason for the damaged phone.
Any ideas??
Regards
You didn't mention if it charges via USB?
Im in the same situation..
charge via usb but is not able to recognize the phone in any computer (a lot of different cables with 3 PCs)
My unit was wet and i think that something is wrong for this reason.

Hi Cento50. Have You managed to get the phone to work? At first my phone was showing up in "This PC" on Win 10. but after trying Samsung usb drivers to get Odin3 working now it is the same as Yours. Shows in Device Manager as: Unknown USB Device (Device Descriptor Request Failed). A strange Conundrum.
Hello @Photobil2012 yes fix habe worked!
One little wire have replaced 2ohm resistor.
And have fix fast charger and data comunication with PC!
We i have repaced first one diode.
Phone a this time work complete.
First this problem i have connected one hard disk to otg cable with phone battery low!
My suggestion Please caution to use otg interface with high current if have low battery in the phone.
This cause high current drain and possibile burn diode and resistor.
Hi Cento50,
Alright! Thank you very much for the most timely reply and tech info on the successful fix. This is very good news to receive. I just replaced the battery so it is brand new and that works fine now. However, if it is necessary I can apply the same type of fix that you applied. Great work, and thanks again for your help.
my nexus 6 will only charge no data transfer and pc wont recognize it. When i connect it to the pc it goes staright to charge mode and the usb trident symbol doesnt ever appear. In developer options usb configure is stuck in "charge mode" only. Ive tried different roms from pie to mm . i reinstalled bootloader and radio, tried twrp back ups and still the same. Had new charging port put in phone thinking that was the problem but didnt help. Ive searched google but couldnt find anything. Any Ideas, really appreciate it thx
When I installed stock rom which was android 7.1 it changed phone back to encrypted. Now i have to format internal drive in order to install a pie rom. Does anyone think that formatting internal drive might fix problem with not being able to do anything but charge phone from usb port, because if that doesnt fix it there would be no way for me to put any rom on my internal drive to install it.. Does anyone have any suggestions

Just to double check that adb devices shows your serial #. If not, it may be a driver issue.
Computer doesn’t see it, when I enter adb devices it doesn’t show up. Nothing shows up in device manager either: Also when I enter fast boot on the phone “power lower volume button” it says “connect usb data cable” I’ve trued numerous cables that work fine on my other phone. So it’s not the cable. After I plug them into phone it still says connect usb data cable.
I also have a thumb drive with a micro usb connecter that used to work on the phone. Now the phone doesn’t see it when you plug it in to the phone. But it works on my other phone so it’s not the thumb drive

It sounds like a driver problem. Is it a windows PC? Have you tried installing the Google USB driver? I've had similar issues, and reinstalling the driver(s) has worked for me.
It’s windows 10 and I reinstalled driver, other thing is in my car when I plug it in to the usb slot for android auto, it doesn’t show up in my car either and it used too.
It’s like the phone is stuck in charge only mode and I can’t get it out of that

When you connect your other phone to your PC, does its serial # show up in adb devices? If so, I'm out of suggestions.
1 more thing.. Have you enabled USB debugging in Developer Options?
Other phones shows up and in devolpers options in “usb configuration” you can set it to mtp but when you hit enter it goes back to charge only. I was on” aiop 14.0 rom” when it happened but it was working fine on that rom , then one day android auto kept saying connect usb, so when I got home I tried to plug it into pc and nothing. So I replaced charging port thinking that was problem but it didn’t help. Flashed other roms and even went back to stock, reflashed bootloader nothing helped. I was hoping someone here had seen this before cause I googled it and nothing like this could I find

Forget USB configuration for a minute. In developer options, under debugging, USB debugging needs to be enabled.
usb debugging is enable also. even tried turning it off and back on again, didnt help.
you know when you connect phone to pc and you normally see the usb trident symbol on your phone, well when i connect it to the pc i dont see that symbol it just goes straight to charging but even charging i should still see the usb symbol and i dont,
So I have this strange issue, when i connect my phone windows says "Usb device not recognized" and my phone is just charging without any notification for file transfer option. even tried usb debugging no results. When connected in fastboot mode windows doesnt even show usb device not recognized. no action in windows. I have tried almost all basic fixes and also have replaced the entire charging board. The bootloader is locked.... and i wanted to mod the phone but unfortunately it doesnt connect to pc.
