I noticed that recently, the phone will charge via USB but will show up as an unrecognized device. No option to activate "mass storage" to connect like it asked before. Tried both with/without Debug mode. Also tried to *#7284# USB PDA->Modem->PDA like i've read somewhere. Didn't fix the issue.
Any ideas?
Thanks!

I just tried. I inserted a toothpick under the usb lid, it did push it up a little and is now centered but it is still not working :/

not the lid, theres tabs within the usb slot on the phone that u have to fiddle with, if thats what u did then maybe u need a repair shop unless its still under warranty

Yeah sorry, I think that I used the wrong term. English being my second language, I some times mix up some terms.
Inside the usb assembly, there is the connector with the 5 pins. Pretty much nothing else is there. I lifted the whole connector to make it vertically centered.
Would the issue be coming from a badly soldered connector?

anyone else have this problem?
I have the latest HTC Driver.
When I first got my phone it was perfectly normal until I rooted my phone. I would have to try plugging and unplugging the Stock HTC USB multiple times for my computer to recognize my phone. It is getting pretty annoying. I was wondering if anyone else has this problem as well. (doesnt matter which ROM I use, problem continues.)

You sure it's not the cable ?
Or, perhaps the usb port connector on the phone, or the one you're trying to plug into could have loose/damaged contacts?
Obviously, somethings changed or different. Try to replicate as many of the conditions that you had when it did work, as you can.

I'm talking about the cable itself, and maybe that's what you are talking about when you say "htc phone charger."
As far as "something wrong with your phone inside," you perhaps are missing or not understanding what I'm referring to.
Look at your phone up close at the part where you plug it in. Real close. You should see 4 little metal strips... Contacts. I was trying to suggest for you to check if there was a physical issue, loose, bent connector on the cable or on that part of the phone.
Or, on the connector of the port on the computer you were trying to connect it to.
The fact that you have to do it several times for it to recognize, but that it at least DOES eventually recognize it, made me suspect it's something intermittent, like a bad/loose connector, or a cable that has one of the wires inside it broken.
I don't know what other than something having to do with the usb connector on the phone, possibly where it's soldered to the PCB, that would cause it to intermittently give you problems.
Here is my case, I am now on stock 4.1.1
When I connect my nexus to my PC, it only charges. I can neither mount USB storage nor attaching to debug mode. What even worse is that, I can't even run fastboot command in bootloader, so basically I can't flash a custom recovery.
As a result, I am now stuck on stock ROM.
Can anyone please give me an idea to get my USB driver work, or at least to flash a recovery?
EDIT: I have used fast charge before, so will it screwed up or disable the USB driver? Any way to restore it in my case?
EDIT: Solved. The two USB line charges only
Can anyone help me?
I have tried two USB lines with two PCs, so I do think there is a problem of my phone.

Hello barrielui,
would you describe more information how you solved that issue? What do you exactly mean by last line? It's working only for "charging" or for data transfer (mass_storage) too? You've found new type of USB cabel or what?
Unfortunately have the exactly same issue few days after upgrade to JLB 4.1.1 stock Rom. It works properly few days and than from some reason something happen, but don't know what&why and how to fix it.
Think maybe it's a hardware problem, but how it happened is mystery
I had issues with my usb for a while myself, it just kept getting worse until I would not get a charge at all. Your issue may be different than mine, but I had my nexus s the first week it came out. I had already planned to have my phone sent in for repair on my usb, so I figured I could tinker with it. It turns out that the little tab in my charge port was pushed down (away from the screen when holding in hand) just enough that it would barely make contact with my micro usb cables. I used a tac and slipped it in between and carefully pried up a little.
Caution, this may not be your problem, look at other options, or compare your usb port to another phone to determine if it is it. My tab was just barely gaped from the bottom.
Solution
Try cleaning the Nexus port pins with something pointy...deposits on pins inside cellphone port prevents the usb contact..clean it one by one with a pin and tell me if it worked

It was a hardware issue with USB connector on motherboard on my case, but strange is that it was occurred when flashing to newer system.
Hello everyone,
A couple of weeks ago my USB data connection on my OnePlus One has stopped working.
This means that no connection is even detected on any computer.
This is not a driver issue as the computer doesn't even notice anything has plugged in.
I think it's not a software/ROM issue because the same applies to fastboot mode and recovery mode - no data connection, no "usb plugged in" sound on any computer, no device showing up.
It's also not a cable issue, as the same cable works on other OnePlus One's and I've tried many different known-to-be-working cables.
More facts:
1) When plugging to a computer USB port - the battery icon shows the charging (lightning) symbol for a half a second and disappears and it won't charge. The computer, of course, doesn't see a usb device plugged.
2) When connecting to an AC charger - it charges just fine.
3) I already tried replacing the dock connector and flat cable unit with a new one - did not solve the issue, which means the dock connector is fine.
Any insight on this will be greatly appreciated!
Thanks!

By dock connector, you mean the USB port? Typically, this issue arises when the pins in the USB port get damaged. I don't know how the rest works out, but if that particular section of pins have to communicate throughout the rest of the motherboard, perhaps the trail responsible for that may have somehow gotten damaged. This is a clueless theory, someone with more electrical/motherboard experience can verify this.
What I do know is that once the micro USB port has been replaced on the phone, the issue should be fixed. It happened to an S3 I still have and I got it replaced by a friend. Sadly, it happened to me at the wrong time since i had wiped the entire OS and internal storage and was relying on my USB OTG cable and a flash drive which contained a rare rom called Sonic Open Kang Project (SOKP).
DO NOTE that this has also been an issue with me on the software side of certain devices. I uave had practically every flagship device out there and have come across a point where this happens on both stock and custom roms. My Optimus G did it on custom roms, and my Nexus 7 2012 occasionally on stock. There were other devices I cannot remember but sometimes factory resets or replacing the rom helps. However, you did state that the result is still the same on fastboot/recovery, so this seems to be more on the hardware side.
I replaced the USB connector (including it's flex cable) entirely. Did not solve the issue.
What else could be wrong?
try again

Try another computer. See if you can get any response from adb.

I tried a lot of different computers and cables. None of them detect a USB connection.
Again, to clarify - they don't even SEE a usb device has been plugged in.
recovery?

You running a custom recovery? If so, see if you can toggle the mtp on/off reboot with each back to recovery. Use the tools to check the filesystem, permissions, etc.
Could pins have damaged?
Well, I did replace the USB connector with a new one, so if pins are damaged it's gotta be on the motherboard side, and I can think of no reason why that would ever happen.
As for recovery, I'm running TWRP and I'm not sure I understand what you meant I should try. Can you elaborate?
Thanks
Hi! My mother's S7 is not recognized by any PC right now. Before I order a new USB PCB I'd like to ask for some help here. The symptoms are:
- Charge and fast charge fully working
- Everything inside the phone is workin, not a single scratch
- When I plug in to any PC, no data mode transfer appears, neither under quick settings, just charging.
- Windows doesnt recognize anything when the phone plugged in, seen on device manager.
Did you install the Samsung USB drivers?
9 times out of 10 it is the USB port. This can be replaced by dismantling the phone and connection a new USB ribbon.
If you have tried this and ruled out the port, I had one where a dodgy charger had fried some components between the USB ribbon connector and the multiplexer IC. I had to replace components ZD8008, ZD8008, R8019 and R8020. These serve as input protection on the USB data lines.
Someone with microsoldering repair experience will be able to replace these for you. You be no more than 75 Euro. It does involve dismantling so may void warranty/water resistance.

I guessed so. Where can I find this components? Are they smds resistors, capacitors? I know microsoldering but does it deserve the effort? I mean, can I found a USB pcb replacement and just replace the whole piece?
Thank you very much!
EDIT: Like this one
EDIT2: I missunderstood your first line...I haven't already tried to replace the usb pcb. I think I'll try and if it doesn't work, well... I hope not -.-"
I draughted this reply before I saw your edit; sounds like you know what to do though: :good:
Sorry, it never occurred to me that you hadn't tried a new USB port flex yet. 9 times out of 10 it is that. Get one to try; fitting it is a pain because you have to separate the screen from the mid frame for the back/app button backlights but you can test it without removing the old one. They are very cheap and available on eBay etc.
If the new USB doesn't help, the fix is probably the microsolder repair I described above. Those components are in the main PCB so a USB daughterboard swap won't help.

Hi Guys,
You may have seen me complaining about the op6 here before, but now it has become a paperweight.
It all starts when no computer I use recognizes the OP6 (USB device not recognized) anymore, this happened after I asked for technical assistance to change my usb input from him that was having problems. But so far so good, because I'm not much of a copy data from my cell phone to my computer via USB.
Then came the problem, it presents the CrashDumpMode error that we have seen a lot here in this forum regarding this device. And then, as my computers don't recognize my cell phone anymore, I can't use MSMDownload to make the system recovery and the cell phone back to normal. This is about 2 weeks ago
I opened my cell phone yesterday, to remove the flat from the usb input, and try to clean, clean contact, etc... Soon after I reassembled the entire cell with all the flats as they were before and the cell didn't even give any sign of life.
What do you think might have happened? Did his motherboard take its last breath and die for good?
Hugs
You may have damaged the connector contacts.

Any you removed. They are easily damaged if misaligned. Best to use a very fine pair of tweezers and visual aid if needed. Pull and inspect for damage.
ESD protocols/procedures should be followed as well. The out of circuit subassemblies can be damaged by static electricity.
