Ever since going back to (downgrading in my opinion) from an AOSP ROM to a Samsung-based ROM, my USB connection to PC doesn't work reliably. The phone detects it is plugged in, USB debugging is turned on and I have the correct Samsung drivers installed.
But it's a crapshoot whether or not the computer detects the phone being connected. Sometimes it will work, sometimes it'll take a couple of minutes, sometimes it will require me to plug & unplug the cable multiple times.
It's highly annoying, especially since I had no issues with it whatsoever when I was on an AOSP ROM.
Any ideas?

Ok.
So at some point I soft bricked my phone and I got the Phone -- ! -- Computer screen.
Managed to get it back into download mode, and then unbricked it by getting it flashed to EB01 as instructed in this thread
http://forum.xda-developers.com/showthread.php?t=1026746
So now I have EB01, which is working, however there is a new problem.
When I try to plug the phone into a computer, it is not recognized (Says the device has malfunctioned).
I have tried 3 different computers. I made sure I used the cable that came with the phone.
I brought it into the Verizon store, and they were unable to get any of their computers to recognize the phone either (we tried a few other cables there as well)
This is both in download mode and within the OS itself.
They told me to try downloading Vcast however that didn't work either.
So now I'm wondering if there is something I can do to get it to recognize it properly again.
Has anyone run into this situation before and managed to fix it?
I did twice have the phone plugged in via usb to my car, and walked out the car (was talking on the phone), and the USB yanked out, so that could have potentially damaged it (though it still charges, so I don't know)
Yanking it out could have very well done it. Only thing I would suggest is reformatting the drivers and attempting again this time leaving it plugged in and rebooting the computer. If that doesn't work, replacement time.
Do you have "usb debugging" turned on?
Did you activate the connection from the phone after connecting to computer? (mine shows a green screen with a button to activate the connection for mass storage)
beyond that... idk.
redownload the samsung drivers
based on the fact that so many PC's have been unable to connect and the info on yanking the USB charger in the car (I think we have all likely done that - though for me it has happened at work with the laptop<->network cable...) you may have damaged the plug/receptor (not sure what would be proper...).
I would do a visual inspection for kicks, though I am sure there could be damage you cannot see.
I believe that these USB connections are a minimum of 4 conductors (some devices are more proprietary and use more pins to ensure you are using an official cable so they can get you to buy more of their stuff - though some of those pins are not actually wired through the cable, but rather short to each other...). If you damaged only one, that could likely be the reason that you can get a charge but no data comm - and since it seems likely that one of the two data pins would be tx and the other rx, then I could see why teh PC would report the device had malfunctioned...
I am guessing here - logic, please don't fail me...
I have an un-rooted, bootloader unlocked, stock att rom that will not charge or be recognized by the computer while turned on. With the phone completely powered off, it will charge. In the bootloader, fastboot connects via USB with no problems. When I go to TWRP recovery, a USB device is connected for about 10 seconds, then it disconnects. With the phone loaded and running, I plug in the usb cable from the computer and nothing happens. The computer does not make the sound of a device connected, device manager doesn't show anything is connected nor will it charge. If I plug it into a normal wall charger, it still won't charge. My other HTC One works with these same cables. I already reflashed the stock RUU with no luck.
Any ideas what could be causing this?
Looks like an rma on that one boss...imo or try another computer possibly
I'm asking for a solution to get my phone to charge via PC when phone is on. I've been troubleshooting this for days. I have a Sony Zperia Z Ultra, so the battery cannot be removed. This is what I've determined:
Phone charges when OFF and connected to PC.
Phone charges when plugged into wall.
Phone shows USB debugging is active when plugged into PC.
-If USB debugging is disabled, phone will not show any indication of being plugged in.
Phone's battery status is "not charging" when plugged into PC.
PC shows phone in device manager.
-Device manager shows yellow triangle next to phone name regardless of the PC I use (all of which previously worked fine).
-Have tried uninstalling and reinstalling drivers but all PC refuse to recognize the Sony drivers for some reason. I'm also at a loss on how to get the drivers installed properly, or how they got messed up in the first place. This happens for all PCs however. But regardless of drivers, the phone should still be able to charge once plugged in. It does not.
-If USB debugging is disabled, phone will not show up in device manager.
PC makes USB connection sound/notification when plugged in.
-If USB debugging is disabled, PC will make no sound/notification when plugged in.
PC will NOT show phone in Explorer (SD Card does not show up, nor can you navigate phone directories).
Have tried 3 different computers and laptops.
Have tried 4 different USB cables, both third-party and branded.
Have uninstalled recently installed programs (from both PC and phone).
Have tried resetting, rebooting, and hard rebooting phone.
Have tried cleaning the mini-USB port on the phone, it's nice and shiny.
Have used phone for about 6 months, problem just started happening about 2 days ago for no apparent reason, no changes were made on PCs (tried several) and especially not the phone itself.
Any ideas? I can only assume it's a phone issue from using above factors to narrow it down, however which phone factor should I focus on?
I've tried everything I can find on the web to repair this sm-n920a. Any time I plug it into a computer it comes up with a usb error.
I've even replaced the charging port, with no luck. It charges fine, doesn't appear to be any damage, tried 5 different usb cords that are working fine with other phones.
The ultimate goal for me is to update it to nougat, but the ota won't push on it from at&t, and obviously I can't force it to update plugged into the computer.
This even happens in download mode.
This happened to a lot of these phones, the ultimate real fix it seems to be replacing the mobo, but would like to know if anyone has any real fix, or a way to work around it to install nougat. I've tried a dozen things to get it to try to push nougat too with no luck.
Since these phones dont even have an sd card I can't even load files onto it unless maybe by bluetooth?
I wonder if I moved nougat over to it by bluetooth could I then get it to install somehow?
I just verified it's definitely something wrong with the phone cause I can insert a usb dongle that I have and a usb drive which comes up fine on my note 4, but doesn't appear on the note 5...although the light on the usb drive turns on, but it just doesnt see it...so there must be something wrong with the drivers on the phone, or something on the phone end...any help would be appreciated.
usb host check shows usb host not enabled on the phone. Can only "fix" it it appears with root, can't root without usb access.....daaaammmnnn
So as the title states. I am having problems with getting MTP options while plugged into a computer. It sometimes works and others doesn't but it seems to work once on a first try on a new system and then the next connection it is only charging.
I was thinking maybe faulty port or cord. As I have tried several cords which also work on other phones I ruled the cord out. The port I have tried unplugging and replugging several times with no success, also jiggling the cord a bit while plugged in. No luck. It just randomly works fine once in a blue moon and then does not.
I have made sure my phone was unlocked, switching options in USB configuration setting though not the notification option because it is not there while it is not working, USB debugging on/off, restarting the phone, simulating a battery removal reboot, installing windows drivers, removing the sim card.
The phone is rooted with a custom rom for marshmellow. Can't really reset it or flash it without a computer to my knowledge. Was considering trying out Nougat but with the current situation I am not really able. Any help, ideas or insight would be greatly appreciated!
