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

I tried turning on The MTP option in developer options , still no luck.

I really hope you found a solution. Ive been looking an answer for this annoying problem for 6 months!
Ive read almost 50 threads in differents forums about this problem but no solution at all.
- Tried changing charging port. Cost me a few dollars but no solution.
- Tried USB debugging on and off from developers menu.
- Did MTP+ADB option in *#*#0808#* menu.
- Turned Low Battery Dump "on" in *#*#0808#* menu.
- Tried 10 or more different original Samsung cables.
- Upgraded PC USB drivers.
None of them worked for me.
Hope you have made a progress.
I just upgraded to Android Oreo via OTA. When I go to plug in the phone to my computer, it doesn't show up. In the Device Manager is has "Unknown USB Device (Device Descriptor Request Failed)".
When i swipe down, I don't even get the option to change it from Charging to PTP
Is there an updated driver that I need for the new update?
I'm running Windows 10

You can try to reset and setup the USB debugging settings and configuration in the developer options.

No there are no new drivers to install. Try a different cable/port. If you are using USB-C to USB-C, try a USB-A cable. As mentioned revoking/enabling USB debugging might help. If you are unlocked you can install TWRP and use MTP to take off any files you need before factory resetting.
None of this worked. I've reset the phone twice.
I had this problem. Try plugging it on a different computer and see if it shows your files and reads the phone. If that happens. The drivers in your pc is the problem. I would try to uninstall and re install google drivers.

Okay, but resetting the phone is not addressing the different PC/port/cable possibilities. It could also be the USB port on your device but it sounds like a PC driver issue or cable. Try a different PC and see what happens.
So yesterday I tried installing the bancontact app and it said that i needed to disable developer options so i did,
this also disabled my OEM unlock what i didn't know.
This night i went to sleep and plugged in my phone and the charger became incredibly hot so i unplugged my phone and it went empty.
This morning I try to start my phone and get a message that my custom binary is blocked by FRP lock so i start my pc and start Odin.
But the problem is my pc sees that a device is plugged in but it gives an error message that says "USB-Device is not recognized" so i tried to install the Samsung USB drivers which didn't help.
The device is listed in device manager as an "unrecognized USB Device"'
Now I'm starting to think that my port is burned out but it's strange because the phone does charge and does pop on when i plug it in the charger.
I tried different USB ports, different cables, different drivers and different PCs, nothing worked.
I tried searching for drivers to install manually but didn't find them
Can someone please help me?
Thanks in advance

Okay so now I tried one more time with a broken USB cable (it disconnects when i move a bit) and this one worked for some reason so my problem is resolved.
