usb problem - Galaxy S6 Q&A, Help & Troubleshooting

hello
i have a galaxy s6 root and run xsterolite rom. when i plug my phone to my windows 10 pc or macbook nether one of them recognize my galaxy. it say charging but nothing else. i update the driver and so on but nothing helps. even putting it in download mode and starting odin nothing? also google it and there was nothing. any ideas what to do?

What kernel are you using? It seems like the phone is in a charge only "state"?. You don't say what S6 you have? 920F? If so, try to flash Hacker kernel from here . See if that will help.

I have the same problem.. no recognition on pc only charging.. slow charging...
When i connect a usb otg hub then no recognition for the hub.. only thing pops up in the notification bar is: usb controller connected and then nothing.. tried everything.. secret codes for usb.. all seems right.. but no recognition only verry slow changing.. and damn i realy want to connect with odin for fixing but.. you can fill the rest for your self in..

Try download Shortcut master lite from playstore, run secret code explorer in it, then code 0808, and set AP and MTP+ADB to see phone as disk in windows, this helped me, hope it will help you.
Offcourse you can also try dial *#0808# and see if that works (rom dependant)

Thank you for answering!
To bad that i already tried it.. and still nothing happens

Send it back to Samsung for a warranty repair. Seems like your usb-board and/or mainboard has a problem. I had exactly the same problem, only slow charging. Got it back with a swapped mainboard and new USB-board.

Thank you! Now i know it for sure! I go to samsung with the device! Thx

I have the same problem. I send it in for repair under warranty but Samsung told me that "every change of the original software (it doesn't matter if the problem occurred because of the software change) leads to loss of the warranty." They wanted to charge me 490$ to fix the problem. I denied and changed my daughterboard by myself but the error is still there.
I think somehow we f*cked our Mainboards up.

Any possibilityto flash soft SPL(REverting back) from MicroSD???

Hi All,
I am havin Orange branded Kaiser.
All of sudden Sync not workin, so cant connect to computer, so I have decided to send it for repair.
But now problem is cant revertin back to soft SPL, Guys any Idea I can flash SPL through the MicroSD.
I am really stucked pls help me, will really appreciate
Thank you
sounds like your **** out of luck did you read the sticky on the top that explains how to do so? and maybe the rom you flashed was causing active sync not to work? was the phone charging? did you have the settings set correct seems like a strange thing to send a phone in for repair for to me
Can't sync is usaly a setting issue. Hard-Reset device first. If it still does not sync, send it back.

I completely agree, try other USB ports and try another computer.....
Thank you 4 yr responses Guys
I already have tried with diff. sync cables and diff. computers. I tried diff ROMs(includin HTC original shipped) as well but nothing happen.
It does charge the device perfectly but One thing is bit weired it is when you enter in bootloader mode(Camera+Power+Reset) on the top in tri color screen it shows the info abt SPL version and at the bottom it shows "Serial" and when you connect to PC with sync cable it shows "USB" and if you connect with power cable only it stays with "Serial" so at least device itself recognise connection type which is normal but doesnt connect with PC, there must be something blocking the connection in the device, what I think there could be a virus.
I am really in trouble, I desperately need original SPL to revert back 4 warranty
Pls help me
Thanx

yeh i've checked everything. i even use the different port. and cable. also tried on the other two laptop, which is the same thing T____T, i can't even charge my phone from the computer, which is the saddest.
anyone know how to fix it? i tried some way, which is from the windowsXP help and support center. i've done everything but still the same. i took it to some stalls and asked if they can fix it,and they have no clue D:
HELP HELP T_T
Ummm, I guess you tried soft reset?
And / or hard reset?
So its not recoginised at all then. Um try going to device manager and then uninstalling the driver and then press scan for new hardware and see it will reinstall correctly.
Before this reboot the computer and phone and try again as Bodisson said, that normally does it tbh
Ummmm.... maybe you could also try reinstalling ActiveSync on PC.... before SR/HR...
I have the exact same problem. I can charge but no data connection.
Tried on different computers and OSes. No luck.
I'll try to check if any pin got damaged.
where can i get the drivers for it?
If problem is only on your PC, try following:
Uninstall ActiveSync. Reboot PC. Reinstall ActiveSync (ver 4.5 - do NOT keep any previous settings for it).
That should normally be enough.
Also be careful: Similar thing can occur if you're syncing with more than one PC!
Device is sometimes recognized, but you can't sync at any time.
If problem occurs on other PCs too, then I'm afraid you have to go trough hard reset procedure.
If even that does not help, I'm afraid it's repair center time...
I had this problem, the only way for me to solve it was to have it sent to the repair centre, they changed the mainboard, and since you say that you have flashed it you havn't got any Warranty left.
I have an official Windows 7 PRO, and I use it since july with Win 7 RC and I don't know why but I have the exact same problem for 2 days now !!!
It worked fine and then, out of nowhere, now i got usb connection problem !!!
I did at least 10 hard reset, and it's the same problem on the lab top of my wife!!

[Q] Hero trackball/pc connection problems

Hai people,
Im new here and i got a problem with my HTC Hero. Ive got it rooted to FroydVillain through this site and it worked fine for quite a while. But since thursday my phone flipped.
My trackball keeps lighted on, whatever i do. My battery runs low in like 6 hours...normally i did a whole day with it.
When i plug the usb cable it doesnt connect to my computer, it only starts powering up the battery. If its connected with my usb cable and i remove the battery the trackball starts flickering instead off burning all the time.
I didnt know what was going on, so i tried to do a nand restore in the root menu. After that i still had problems with the trackball and it still doesnt connect to my pc. Then i tried a factory reset in the root menu, but the problems are still there.
It doesnt let me get into the mobile network settings either. It doesnt find my provider and cant change it, so at the moment my whole phone is useless
Im quite new with this whole rooting thing, so i might have messed it up now? I hope some people know a solution for this. Please dont throw to geeky stuff to me, because i might not understand it
My software settings are this according to the phone:
Firmwareversion: 2.1 update1
Smallbandversion: 63.18.55.06PU_6.35.15.11
Kernel-version: 2.6.29-063c4d24 htc-kernel(at)and18-2 #1
Build number: 3.32.405.2 CL 191507 release-keys
Softwarenumber: 3.32.405.2
Browserversion: webkit 3.1
Any help is welcome! Thanks in advance
I have tried to fix it myself cause i didnt get any responds yet, but without succes. I got it to restart again in the original htc version, and get the setup menu where u can set your country, wifi connection etc...
It doesnt recognize my sim card though, and doesnt find a provider because of that. When its finished with the setup menu its at the 'normal' home screen. But as soon as it turns black as the screen saver i cant get the screen on again.
The trackball also still keeps burning.
I went to my local phone repair point, but they dont do androids :S its for nerds he said -_-
Im getting hopeless...plx could some1 tell me what to do. I want a whole reset off the phone...i dont care losing information on it. But because i cant connect it with my computer i have no idea how to flash a rom on it

[Q] Screen On with "USB Device Disconnected"

My Galaxy Tab 7.7 turns on every few minutes and displays a message for a moment in the lower right corner. The message is "USB Device Disconnected".
The device is not connected to any USB device.
This has been happening for many weeks now.
I've tried to turn the USB Debug option on but that didn't change anything.
I have not rooted the device.
I have not flashed the device.
I am running only stock applications from the market.
Does anyone else have this issue?
It's maddening because the device constantly turns itself on. At night I either remove it from my bedroom (the display lights up the room when it comes on) or turn the device upside down on the table so I can't see it when it comes on.
yes, i have the same issue
no idea what the reason is
Same issue.
One Added Note
One item to add...
It appears that if the unit is charging it does not have this problem. This makes logical sense as the USB is connected, albeit to the wall outlet.
I'm going to wait until ICS - which is due here in Thailand at the end of this month. If that doesn't fix it I will contact Samsung.
Living here in Asia makes taking things back for repair very difficult as the many small but authorized vendors aren't set up for this, the language barrier adds heavily to the issue, and finding an English speaking official Samsung office is quite difficult.
I will monitor the forum to see if a fix arrives before my software update.
Thanks everyone!
Same problem here. When this happen for me the mobile network disconnects, I am thinking that it may be some problem with the mobile network card...
When connected to wifi this is not visible although i might get the usb message.
But on 3g i loose all connection sometimes only for a second but sometimes for up to a couple of minutes...

Update
I wanted to add some more information...
I happened to remove my carrier's SIM a week ago and the "USB device disconnect" error continues at the same rate.
I guess my next question is how do you contact Samsung support?
Do they have a Tablet support phone number?
I don't care which country the support line is located within, as long as it's English-speaker focused.
bump
very annoying to lose mobile network all the time
I changed Galaxy Tab 7.7 (3G Version) three times, all three tablets had same problem.... any idea to fix it?
I think the problem gets worse if the tablets not been rebooted for a while.
But after reboot I think mine is a bit more stable.
How is it for the rest of you?
---------- Post added at 10:50 PM ---------- Previous post was at 10:49 PM ----------
I also find it weird that you have the same problem with three tablets, but at the same time it seems that very few of us are affected???
I called Samsung and they said they never have complaints on this issue.... anyway, i got three devices from different stores have the same problem.. I think the issue is the rom. That problem hopefully can be solved after ICS upgrade...
Same problem; not so often but it happens once in a while.
I don't know if it is causing the instability that I have noticed with this device but it is kinda weird.
Do you have micro SD card plugged into the device? I read some other forums and some people removed the micro SD card, the issue resolved afterward.
I just removed the micro SD card, I will let you guys know if the issue can be fixed or not soon...

Solved
I think all this happens because of Kies software. It's a monster, I will never use it any more. Even uninstlling may not help. Better use MobilEdit instead.
Anyway, I found solution in registry. So, try this:
Before starting, disconnect all usb devices from PC
1. Open Windows registry editor
2. Open key HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Enum\USB
3. Press CTRL+F and search in data value your device name (egz. Samsung)
4. Delete all key branches with name started: Vid_*** where your device will be found (You may have to enable permissions first).
Reconnect device. That's all
i have the same 'problem' but..., never used Kies software
Anyway, solution is in the registry. Evidently some usb drivers are conflicting.
Deleting those Vid_*** keys simply resets usb drivers on particular port.
You can check your phone on another computer without driver

I don't see how this has anything to do with the problem.
The USB device issue is happening on the tablet, not on the PC. How does removing USB drivers from my PC fix the tablet issue?

Sorry, I didn't notice, that device is disconnected
Same problem with GSM version. Could someone try log at the logs when/after it have happend? Dmesg and logcat. Will also try to do it myself.
same issue here. Never used kies before. I'm not sure if it has something to do with interfering gadgets near the tab.
Strange thing some (or most) people dont notice that bug(?). I tried several 7.7's now and can confirm that this looks like rom issue as every 7.7 has that problem. It really annoys me, escpecially combined with the battery status screen-on bug. When battery is lower than 10% screen turns on like every 2 minutes or so... Good thing to save remaining battery
Oh and I never used Kies too. Didn't even install it yet.

Android File Transfer (Mac) not working?

Anyone having issues with AFT and the GS7? When I plug in the GS7, AFT launches but I get an error that the device is locked, even though it isn't (screen is on and it's unlocked). I've tried removing security just to eliminate that, doesn't help.
Other Android 6.0 devices work fine with AFT so it's clearly GS7 related.
Particularly annoying because you can't yet write directly to the External SD card

When you connect S7 to the MAC, it says cannot connected, but a popup appears on your phone. Allow it, and don't disconnect the USB cabel. Once again, start Android File Transfer App. This is how it works. Each time when you plug S7 in, you have to allow the connection on the phone, after that it works until you disconnect S7.
When I plug mine in and change the setting to media transfer on the phone AFT pops up and says "try reconnecting or restarting your device" then closes. Every time

Please don't assume we're rookies. It does not work. Even after clicking "allow" for permissions, it fails every time.
Also don't assume every variant is the same.
For anyone who seems to be hitting a dead end, this completely solved my problem...

You mean after allowing and not pulling USB cable out? After allowing just open Android File Transfer app again. DO NOT REMOVE the cable!

Your solution didn't work for me, I still have to allow access for the computer each time I connect the S7. After allowing it works flawlessly.

Yes, that's true. I couldn't get it to connect no matter what, without uninstalling Kies. That was my OP.

OK, I found a real solution: install Samsung Smart Switch and update it. When phone is connected (don't have to allow) there is a small arrow on the right side of the name of your device, expand it, and a small folder icon opens a file manager like AFT. By the way it has also a backup/restore/update/syncMAC function without root.
If you have been getting a response when plugging in a Galaxy S7 or Galaxy S7 edge, do the following:
Go the the Kies website and download Kies for Mac.
Next, openKiesMacSetup.dmg which you've just downloaded.
Click Uninstall. Your Mac will ask you to open the app, so you'll need to open it.
Once it's done uninstalling Kies you probably had on your computer from a while back and no longer use, once you plug in your new GS7 or GS7 edge, and open the AFT application on your Mac, it should still give you a weird response, but on your phone, this time it'll ask you if you're ready to connect your phone and open it up to see files on your computer. Select that you do, and it'll work.
A Finder window opens, and the model number will appear in the center of the Finder window with the requisite files.
Actually, unless I missed it, nobody touched on the solution, which is incredibly simple. I found it on accident. The default setting for the GS7 is to CHARGE when plugged into a Mac (maybe PC too?). Swipe the top notification area, tap "charging" and switch it to file transfer, or photo, or whatever else you want. Good luck!!!
Fixed it for me just now
I was having all of the above issues. What worked for me was completely removing all traces of Android File Transfer (including other mobile sync applications) with AppDelete. Then I reinstalled Android file transfer, plugged my phone in, tapped "Allow", and it worked!

I struggled with this, as well. I even uninstalled all KIES drivers form my Mac and AFT still didn't work with my S7 until I did the following:
(1) Plug the S7 USB into the Mac.
(2) Down swipe the status bar at the top and you should see a "USB Charging" status.
(3) Tap on the "USB Charging" status and a menu with radio buttons should pop up.
(4) Choose the "File Transfer" option.
After doing that, AFT worked properly and it didn't even require me to click "Allow" or anything else. It just worked.
mickliq's solution worked for me as well (hadn't been able to connect an s7 or s6 to a mac air osx 10.11.4 until downloading and uninstalling Kies). Thanks!

I succeed to solve it by removing SideSync on Mac
I had the same problem and discover that it was SideSync that make Android File Transfer not working.
I remove SideSync on my Mac and then it works !
