I can charge my phone through USB when connecting to my laptop, but it does show up as a device, anywhere. I've tried ADB, Fastboot, and Device Manager. It doesn't even show up in Device Manager as an unknown device (e.g. yellow exclamation point). I've enabled USB debugging, changed the USB configuration to File Transfers, used multiple cables (including the OOB red one), multiple machines (Windows 10 and 7), but I see nothing. No storage drive, no errors, no Windows sound indicating a device has been connected. But still it charges. I thought about wiping to factory settings, but given I'm not connecting via Fastboot or ADB, is that even worth trying?
I'm on OOS 3.5.6 unrooted and bootloader is still locked, although I've previously had other builds and TWRP on it (so USB used to work for data). I figure that OnePlus won't support me because the screen is cracked in the bottom corner, but I don't see how that could have broken just the data pins and not the charging ones. I think I had this problem before I dropped the phone, but I can't be 100%.
Same problem
I too have the same problem , I too have never rooted it ...Never dropped , never rooted but still suffering from the same problem...
There is an option in the develiper options...
That has these issues sorted with
Try it out there or just let me know
Try changing the cable too. The pins might have worn out
P. S I do not have the issue. Suggestions only

Hello every one,
When I plug my Omnia 7 with my laptop, it appears the message "USB Device Not Recognized. Unknown Device (Code 43)." I have tried different ways posted in this forum but non of those worked. I tried to restart my pc, plug off battery, hard format my phone, tried in different laptops, and the other methods, but non of those worked.
I need help please if anyone could tell me what to do I would appreciate.
Try reinstalling zune, maybe even reinstalling sammy usb drivers.
Sent from my OMNIA7 using XDA Windows Phone 7 App
I have to say .... we can spend hours understanding these windows phone
I do not know why a windows phone cannot be synced with a windows computer. Am having the same problem. My device appears as unknown device in Device Manager. I tried to update the drivers from Zune folder, but it does not find the correct drivers there. Any help would be so appreciated.
Thanks a lot.

I think I can help - it may be the BATTERY!
Hi - I stumbled on this thread by accident but had a very similar problem - I will look up the Whirlpool thread where I wrote about it as it was a while ago - but similar symtoms all fixed by replacing battery. _ i dropped my Ominia briefly into water.
Here's what I wrote in Whirlpool forum on 2011-Oct-31 (can't post link as new member) Thread Title "Samsung Omnia 7 i8700 - Part 2"
My beloved Omnia 7 took a very quick dip in the pool on the weekend. Life lesson learnt: "Do not put phone in top pocket as it will fall out."
Anyhow I grabbed it straight away and turned it off – dried it off etc – I was amazed it booted and runs BUT things are not good.
� Phone works normally (all functions, wifi, apps, OS etc.) on external charge either AC or PC USB
� Phone works normally on battery, but it keeps playing an alert chime, will not sleep, and in Settings / Battery Saver it flashes on this screen � and it does not sleep as whatever it�s alerting on prevents idle.
� Goes to sleep when on AC/USB charge.
� After plugging into AC/USB, and unplugging from AC/USB, phone runs normally, believes it is being charged, does not play alert chime, but does not sleep
� Does not interface with PC via USB � plug into USB causes �USB Device not recognised� (tried different cables/PC�s)
� Does enter download mode, but USB not available.
At a long shot, it may be the battery. I know I could buy online (risk it won't be the issue). All I need to do is a quick battery swap test but need a spare battery.
WHAT A MESS. Let me know if you are a Brisso and wouldn't mind sharing your battery for 5 mins....
If replacing battery fixes the problem then GOD knows what Engineering Samsung/Microsoft is upto

I had the same prob here and windows can not recognize my Omnia 7 any more after it caught rain.
I had the same problem on my Windows 7 (64 Bit)
Unknown usb Device , lot of posts have found and at the end it was USB-Cable !!!
The problem was in the length of the cable, with long (1m cable) i can flash but no connection over Zune, after i take cable from my Nokia 15 cm short cable it works without any problems.

What Windows are you using, do you have original ROM on your Omnia ?
For example if you are using some other rom than original , that there you have changed settings for USB port (In Diagnose Mode you can check this)
I am on original German T-Mobile ROM, exact same issue, no cure for now. Looks like an end of life for old good Omnia ...
But I did force update both 8112 and 8773 yet before ZUNE actually suggested the update .So not really in a position to complain.
But if anybody here did a "fully legal" ZUNE update (no flash no forced) then it means that the update itself is a problem and MS / SAMSUNG are responsible (not that it ever changed). Did anyone on OEM ROM with the issue upgrade in a fully clean way ?
Just now noticed - this is similar to the problems mentioned in another 2 threads hot here - just in another case people experienced only annoying "alert ringing". Looks like some of us get hit more severe, others less. XDA gurus - PLEASE spend time on this ! This looks as a massive desease case, last hope is XDA.

UPDATE : after all, this was not software related issue. USB port got rust, 70$ to replace it - all troubles gone, connects to PC and no alarm.

Hi.
Last week I noticed that my I9000 running CM9 has no charging symbol on the indicator. Then I tried to shut down the phone and just charge it turned off, but it immediately booted itself to OS when I connected the cable. When I connected it to computer it just charged without charging symbol and nothing happened. Computer didn't detect it, and the phone also did not detect the computer.
Then I tried to wipe everything (data, cache, dalvik cache) and flashing a new CM10 rom (I had to transfer .zip to phone via bluetooth ) . I also cleaned the connector with alcohol and checked the leads on PCB and everything seems fine. But it still doesn't work.
This morning when I connected it to computer it recognized it and phone asked me to choose USB mass storage. But after few seconds the computer reported malfunctioning USB device. After I disconnected the cable charging symbol remained on like it's still connected. Then I rebooted the phone and again there is no charging symbol and no communication with computer. I also tried few other USB cables (another samsung, SE, nokia...)
Is there anything else I can try or should I start saving the money for a new phone?

If you connect it to your pc in download mode, does Odin recognize it?

No. Nothing happens. I also can't find it in device manager.
Sounds like it might be borked alright. Though if it's still charging then at least you won't have to rush out and by a new phone. Try removing your microsd card and formatting your internal storage, before you connect it. Long shot, but it might work :-/
I haven't connected the phone to pc in quite a while tbh, I usually just download the latest version of Cyanogenmod straight from the browser to update, and use dropbox to send any files I need from my PC. e.g. new songs, videos etc. Though obviously if I was reloading all my music/videos I'd need the usb connection to work.
So I came back from vacation (with a new Nexus 7) and wanted to throw 4.3 on to my N4. I had formatted my computer a while back, so I installed all the SDK stuff, usb drivers, etc... I did a factory image ADB install of 4.3 on my old N7 (to let the wife try) and went to try to do the same on my N4.
No matter what I do, the device is "not recognized" by windows when connecting via USB. In device manager it simply says "Unknown device" with an exclamation mark. I have tried unistalling/updating drivers (says proper drivers already installed), unistalling/updating drivers via SDK manager, nothing...
Sometimes it will get recognized as a USB device (in general, but the same errors) and sometimes nothing will happen with my computer at all when it's connected (i.e. no sound or anything). I have obviously rebooted the phone and computer multiple times, used multiple USB ports and cables. Just to make sure things were working with ANY device I did the uninstall/reinstall of the USB drivers, hooked up the N7 and it was recognized immediately (the new N7, first time I plugged it in via USB). I have tried with debugging on/off, with MTP/camera, everything I can think of.
The only consistent thing is that the device does charge every time it is plugged in to the computer.
I'm on a stock rooted 4.2.2 with Franco 165. I have never enabled USB fast charging, nor is it currently enabled. I also don't generally hook my devices up to the computer, so this is probably the first time since 4.2.2 came out. I also have not installed any new apps in a long time (and I have very few outside of stock to begin with).
The only things that have changed recently...
- I used a T-Mobile sim when I was on vacation (not my normal provider), and I'm back on my normal provider now. I assume that that is not the issue
- I used a car charger extensively while I was away (I don't normally use it at all). By extensively I mean it was plugged in for hours at a time (GPS). It did appear to have issues charging at times, did get VERY warm at times, and toward the end of a long session of charging it did shut off (and had issues rebooting/with the battery after). It is probably a cheaper made "chinese" charger if that matters
- Liteflow also appears not to be clearing notifications properly since the T-Mobile sim was in. I don't know why...
- Battery life in general seems to be decreasing since I've been home. It notably goes down, especially when not in use.
- I still have the system update icon in my tray (I'd like to do it via ADB)
Would the car charger do this? Again, outside of the battery life seeming to die faster, the liteflow issue, and the USB issue, everything else seems to be working normally.
I'm just out of ideas on why the USB isn't being recognised on my computer with the N4.
Wow you have just described exactly the problem I've been having for the past few days! I am in the exact same boat. Bump for exposure and possibly a fix!
Hey guys, I'm really at a loss here. I have a Dev edition Note 4. It is rooted with a custom rom running. Randomly, the phone stopped connecting to computers via MTP to transfer files, I could not transfer any data between the phone and any computer via USB. I tried different cables and different computers. The phone still charged, but did not connect via USB. Then, the phone also stopped charging via USB, I was just getting a blinking gray battery icon when the phone was completely powered off and plugged in to the wall. I read online something about holding Volume Up, Power and Home when the gray battery icon appears and it will start charging again. This worked! However still no Data, but at least it would charge. I read something else online about holding this same combination of keys in Download/Odin mode which I tried, and this disabled charging again! WTF! Now I cannot get it to re-enable. I am at a loss here, is sending the phone back to Samsung really my only option?
I've tried: Different Cables, Different Computers, going in to USB Service Menu with *#0808# and selecting MTP and MTP+ADB, nothing works. I am positive something can affect USB settings in Download mode, but I am at my wits end trying to figure it out.
Any ideas?

Why not try wiping data/cache from recovery and install an official ROM from Samsung)either 4.4.4 or lollipop)
Bad USB port

That is what I am thinking too.
My son has an SM N910F note 4. Completely stock. It suddenly stopped charging after a long international flight and now when connected to the charger the battery charging image appears, but then after a brief pause disappears, and the vibrator motor vibrates continuously at 1 sec intervals after that. The phone boots into stock rom OK and also into recovery and fastboot mode.
I have tried different cables (several), 4 different chargers , cleaned the connector on the phone (and cable connectors) with air and alcohol. Contacts seem to be OK on visual inspection. Cables and chargers work fine on other devices including a stock rooted Galaxy S4. Also, purchased a new battery but it did not change any of the above symptoms. When I tried to access the Note 4 from my Linux PC, MTP showed nothing and adb devices and fastboot devices saw nothing lsusb didn't see anything either. Different cables didn't alter this.
One odd thing is that when I boot into recovery I do not see the recovery menu but it immediately reports that it is installing an update and after a minute stops with the "failed to find command " error message. We are unaware of any recent uninstalled OTA updates though. Then the recovery menu reappears.
Can someone suggest for me what might account for these symptoms. I have no idea, but when the device was not visible in my Linux machine I began to suspect a faulty USB/charging port. Trouble is we are running out of battery charge to test anything now and no way of recharging

Can you boot to download (odin ) mode ?
HW failure
Unfutunately, it is a HW problem. You should the USB connector panel.

Yes, I can boot into Odin mode or recovery, but not recognised by laptop. Also, when charger is plugged in the Note 4 will not boot from power button. But as soon as I remove USB cable it will boot. Also, since posting I tried a factory reset and formatted data and cache from recovery. No change though. Still vibrates every 2 secs and will not boot. Battery does not charge at all during this process.
It's still under warranty so I don't want to try the eBay path suggested by Balint320 for repairing it myself at this stage.
Fixed?
Did you get this resolved? Mine is doing the exact same thing since a t-mobile security update. Have tried the master reset twice and clearing the cache. Tried the original charger and several others.
i am having the same problem on n910g, it just stopped charging.I tried everything, from different chargers to a new battery, but no avail.it just vibrates at 1 sec continuously and does not charge at all.
I still have 1 month warranty left but It was rooted and everything so..if there is a way to migrate to fully stock ROM please guide me, so that I can take it to service center.

The only thing I can suggest is, of you are able to get into download mode, is downloading the stock ROM and reinstalling with Odin. Some suggest holding the power button down for a few seconds after removing the battery to make sure that all charge to components is drained before restarting.
Have you tried installing Smartswitch on your PC to see if it detects a problem and is willing to correct it? At least, it will install the correct USB drivers to ensure Odin works fine. Sometimes I think Samsung need a kick in the butt for their slack approach to software reliability and utilities for maintainence and repair. Try just sending it back under warranty anyway if you can't get it to work. Maybe hardware failure. Good luck.
