None of my computers recognize any of my phones. - Android Q&A, Help & Troubleshooting

What is going on? None of my computers are even seeing any of my phones.
I have two android phones (Samsung Note 5 and S8+) and three windows computers. One using Windows 10 and two using Windows 8.1. I have tried every cable I have with every computer and every phone. They don't even show up in device manager. There's absolutely no recognition that anything has plugged into the computer. But the phones are receiving charge. The USB ports are working fine. They work perfectly well for flash drives and other peripherals like my printer. I've got developer mode turned on for both phones. I've activated USB debugging, and I've tried it without USB debugging. I tried revoking USB debugging authorization and restarting USB debugging. I tried MTP and PTP. Obviously everything is fully updated. AND I reinstalled the android driver! I can't think of anything else to try!
WHAT IS GOING ON? I've never seen anything like it!

[Q] Can't connect to Moto Phone Portal when using USB

I can't connect the Atrix to the Moto Phone Portal using the USB. Just curious if there is a fix to this? Once the browser is launched (it doesn't matter which browser, IE, Firefox, Chrome) it doesn't connect. USB connection is set to 'Motorola Phone Portal' and Moto Phone Portal app says its 'running on on USB..."
Not sure what is going on- connects fine using Wi-Fi... just annoying that it won't connect with USB. Any help is appreciated?
Thanks,
M
are you on a mac? I think it requires the MotoHelper app on a pc - part of the PC drivers.
I had the same issue but I also couldn't connect via wifi. So... I turned off the debug under applications and then it worked fine. But haven't had time to try it with the usb but it may help.
I am on a PC and have the MotoHelper installed, but it still didn't work. Also I didn't see a debug under applications, haven't done any modifications to my phone (not sure if you need to modify to debug or not, but I couldn't find it).
Maybe its a driver issue with my dell...

Not a Dell issue. I have Dell running Win7 64bit and it works fine. Try to manually reinstall Motohelper. Also, under you Windows Start button you should have:
START>ALL PROGRAMS>MOTOROLA>Motorola Drivers>Motorola Driver Reinstaller.exe.
Run this CLEAN and REINSTALL and Selct START - see my attached. This will reinstall everything associated with the drivers and Motohelper. Reboot Phone and PC and then replug phone into PC and select USB with Motorola Portal.
Same Problem
I've tried all these things and mine keeps switching back to USb Mass Storage. If I switch it back to Motorola Phone Portal, it will give me the address for my browser and it will actually pull up the Portal on my computer but then the phone will switch back to USB storage and I can't go any further on the computer. I've rebooted the computer and the phone and nothing helps. Any help
I tried all those things as well, but still no luck. However, my phone stays on Moto Phone Portal as USB connection, but just won't connect/load the phone portal in the browser(s) when using the USB cable.

You should uninstall the Motorola Media Sync from the PC. I kinda like the software, but it does it's own thing to much with out giving me control. I have spoken to Motorola 2nd level support, but the were no help. They told me to ignore it or uninstall it. I uninstalled it. I left the Motorola drivers installed. If you reinstall the drivers it'll ask you to reinstall the Media Sync - say NO.
Once the Media Sync is gone, then the Portal will not auto load and you can have control of the USB settings from the taskbar.
I had a similar issues
....First, Moto Phone portal does not work on Chrome (insert IP address into IE or Firefox)
If you still have problems...
On phone, from home screen
select Apps drawer
select Phone Portal
select menu
select Settings
select Secure login
uncheck Enable login
did anyone come up with a fix for this? i have tried everything in this thread with no success.
USB Cable
I had this problem as well, just happened to have a few extra Micro USB Cables around. I found that the phone will work with some Cables and have problems with others. If you can try a different USB cable give it a shot.
It works just fine with Chrome.
The USB cable that came with my phone does not work.

Different USB modes

When plugging in a USB cord to my phone and computer, i get 3 different options (not counting none) for how the phone should handle it. Can anyone explain what the difference is between them (usb mass storage is obvious and can be ignored).
Thanks
Phone portal gives you some sync options, none gives you... nothing except a device connected to a computer. None is useful for ADB.... Windows Media Sync is useful for syncing media with WMP11

Unable to recognize device USB.

I have tried to connect with the device through USB with fastboot, adb, and just through Windows. It does not show up in the Device Manager at all.
Is this a hardware issue with the device? Seems odd as it was working fine and now it isn't and it has only been sitting on my desk as this isn't my main phone.
By the way I have tried this on 2 different Windows 8.1 computers and one Windows 7 PC.
Try removing all drivers for the phone and reinstalling them and see if it works. Also are there any other phone drivers installed for a different device you may have recently installed? They may be conflicting.

It should still show up in Device Manager regardless of drivers though. Just tested on a computer that has never had a single phone plugged into it and Device Manager still does not detect and devices.
Windows 8.1 has driver issues for the DNA. Though it should have worked fine in Windows 7. But I believe for a device to show up the drivers need to be installed.

try a different cable
The device should still show up without drivers as an unknown device. You can't really mess with the drivers for the device until it shows up. Also on a Windows 7 computer that has never been used before the computer should automatically pickup the device so you can transfer files to/from through Windows Explorer.
I have tried a different cable.
I am starting to think it's a hardware issue with the device itself.
what happens when you connect an OTG cable and a flash drive? Does the activity light on the drive activate?
I have not tried that and I do not believe I have an micro OTG cable. I will have to check when I am back at my place later.
Try installing HTC sync and update it and see if that installs ur correct drivers

Appreciate the replies. It should still detect a device plugged in without drivers/HTC Sync, but I have tried installing HTC Sync and all that anyhow. The PC's can detect other Android devices just fine(HTC One M8 & EVO 4G).

If you KNOW the cable is "good", the port may not be "GOOD". Does the cable work with another device?
The cable is definitely good(tried multiple and they work with other devices). I have been thinking it's the port in the device from the beginning, but was hoping maybe there was something else going on.

Problems connecting to PC

Hey guys. I'm sorry if this has already been posted, but I've searched everywhere on the internet and could not find this same problem. No troubleshooting tips helped either.
I own a Lenovo P2 and until recently I could connect to the PC via USB without any problems. Now, my PC doesn't recognize the phone at all. I mean that it doesn't even show up as faulty device or searching for drivers.
With no computer does my phone connect anymore.
The USB cable is not faulty either, nor the PC USB ports and the phone's jack, and the option for MTP is selected. Despite all this it only charges.
Here is the catchy part as the USB configuration setting seems bugged out for me. No matter which option I choose, MTP will show up as selected, yet the phone will only charge.

Question Couldn't connect my device to computer.

I am using usb cable to connect my phone to laptop but the phone doesn't show any transfer notifications. My device only charges.
I tried uninstalling usb drivers and reinstalling them on laptop which didn't work.
I used the same cable on other laptop and it worked fine.
Is this the fault of my laptop or my device? Can someone provide solution to it?
If it works on a different laptop it sounds like your laptop is the issue. What make and model is it, and running what OS?
