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?

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.

been flashing roms for a while now and everything was great until recently. i have this annoying video pop up problem that i cant seem to figure out if its the phone or what. what happens is randomly the tv/video out pops up and the screen turns to landscape mode. then all sound is lost. ive flashed original stock rom but the problem still happens even running stock. i cant figure out if its the phone and i need to do a warrenty exchange or if its something else. i am hard spld and security unlocked. if anybody else has this problem or had this problem and know of a solution id greatly appreciate it. i dont think its the way i flash roms. i flash with sd card thats formatted fat 32. sim card out and hard reset after first boot.
Sounds like you are describing the TVOUTPopup feature.
Usually, the TVOUTPopup only appears when the A/V Cable (extra cable) is physically connected to the device.
At first guess, I would be inclined towards a faulty USB connector.
yes it is the tv out pop feature. whats wierd is that its the new look from a different rom build. whatever rom i run (right now stock). when the screen comes up it turns landscape and has 4 colorful icons to choose from. internet,youtube,photos,and powerpoint office. once i hit the x button or hit close then it will keep repeating and keep the screen in landscape even though i havent slid out the keyboard. after multiple times closing the app it will stop doing it for a bit but then do it again few hours later.
Since you've tried different ROMs and are seeing the same behavior, I'm inclined to think it's hardware related. Assuming you have nothing connected to the device at the moment except for the SIM, examine the USB connector very closely for signs of damage.
If all looks ok, perform a hard reset and flash the Official HTC 5.05.405.1 ROM/Radio (should eliminate possibility of garbage in ROM) to the device and confirm that the behavior still occurs. If the problem persists, that would confirm it to be hardware.
HTH,
well i flashed the new att fuze rom. so far so good. no popup yet. this happened before though when i thought i fixed the problem. but after running a new rom for about 4 days it came back. if it is a hardware issue then my fuze needs to be exchanged right? thanks for all your help.
I have same issue with my FUZE (constant "Video Out" pop-up message, often switches to landscape mode, sound is off). Have you found any solution to this?
P.S. ...
I have HTC MOZART, NODO Build, unbranded in indonesia.
Now my question is, once every 2-3 weeks, I got his kind of error. Basically The internet connection is gone when this happens, and I cannot update anything, unless of course I connect to zune in my laptop and use usb for internet connection shared from the laptop.
The only way to fix this AFAIK is by restarting the device (or remove the battery, and put back in)... hold the on button until off and turn on again is suffice though....
I dont mind restarting the phone within that interval, it is just weird and I tried to google and looked it up everywhere, I have not got the right explanation. Restarting the phone WORKS every time btw.
Anybody knows what this error is?
UPDATE:
I see that many others experience this and still no answer

There are hundreds of threads around the web about this bluetooth issue but none of them seems to answer questions. So, here it goes;
The solution is so simple you won't believe it. (actually you will) The problem is PC not the phone.
Just keep installing the device. I had to remove/add device at least 20 times. At last it just gave up and some "installing driver software" box appeared. When you see this popup it means you've successfully beaten the computer.
It may happen again if you try to send files to your phone without enabling bluetooth.
You might also want to change your phones bluetooth name. This could be just a superstition of myself. I won't try it again just to test it
Ok, so I have been having a very annoying issue(s) recently with my SGH-I997R, ( Firmware version 2.3.3, Baseband version I997RUXKG3, Kernel Ver: 2.6.32.7-I997RUXKG3-CL366622)
This all started out of the blue about a month ago, I used to connect my phone to my PC all the time for transferring items via Mass Storage, and then on day when I went to connect it to my same PC, I got " USB Device Not Recognized". It will charge the phone but will not connect or show any option on the phone to connect. I have tried 2 Samsung cables and a generic Micro USB cable, No change. I tried connecting to my laptop, same issue. I re-downloaded the drivers from Samsung onto both my usual PC and Laptop, no change. Very very frustrating.
Other issues, I don't know if their related in any way but they all started at the same time.
a) if I place my phone in airplane mode i cannot get it out of that mode without rebooting my phone
b) if i shut my phone down (doesn't matter if battery shows 100% or 25%) I cannot get the phone to turn on without plugging in the USB cable.
c) When I leave my phone charging overnight and look at it in the morning, battery shows 100% but also shows "NO SERVICE" , I reboot the phone with the cable still connected, service restored.
IF anyone has had these issues Especially the connecting to PC issue, Please PLEASE help. I am going nuts. And of course this all happened 3 months after the warranty expired, so both Rogers and Samsung will not help without $$$$$.
have you tried to back up your data, take out any micro sd card and perform a factory reset under /settings/privacy/reset ?
or open it up and look inside for any problems like corrosion?

I have done a factory reset numerous times from both the /settings/privacy/reset, and from booting it up holding the volume keys and doing a reset that way.
And I have had my phone since day one in a Ballistic Hard Core Series case, I take it out once a week to ensure its clean and free of dust/moisture (I work in construction so I try to keep it a clean as possible.) and my phone still looks like its brand new.
Thanks for the response though,
Update:
So just as an update for anyone out there who may be able to assist me with this very annoying issue, the Phone is still doing the same things, and since the last post i've also replaced the battery to see if for some strange reason it might help.
But to no avail.
As well I dont think i mentioned that this phone is rooted. I want to try unrooting it to see if that will correct the issue, but with not being able to connect the phone via usb to the computer, I have NO IDEA on how I can accomplish this. Any help???
Hey guys, let me just start off by saying I have spent almost 8 hours straight today trying to figure this out and dig myself out of a hole I've created for myself, that being said, I'm going to try and be as detailed as possible so you guys know EXACTLY where I am and what I've tried. This post looks long but that's because it is. It's pretty much my entire day's worth of trouble typed out. So just bare with me and see if you guys can help me out here!
I have a T-Mobile Galaxy S4 model: SGH-M919 it has Android 4.4.2. Now on to the problem: I've had this phone for almost a year now and a few months ago I rooted it. Did a simple Youtube tutorial and used Odin to do the work and everything worked out fine. A couple months down the road (yesterday), after using the phone like a teenager, downloading apps and cluttering it up it started to slow down and not run some apps. After thinking about it I decided to factory reset it. All of my contacts, photos, and videos were backed up on Google so I thought "why not?" Well, this is where $#!% hit the fan.. being rooted then factory reset, right before the phone came online it had me answer two questions about the root. Something to the effect of "Do you want to keep root? (This option is not reversible)" I thought since I wasn't using the features I originally rooted the phone for I figured nah just get rid of the root. So the phone did its T-Mobile boot up and started the Initial setup.
Everything up to to this point was fine until I wanted to log in to my Google account during the setup. Please understand that where I am I have full 4G LTE coverage and have access to a pretty fast and sturdy wifi connection. Well, when it came to the google sign in I entered my email and password and it came up with a message reading "Can't Sign in - Can't establish a reliable connection to the server" (believe me i wish that was the only issue) so after reading that, I thought I'd try with my wifi.. nope. Same thing. Since neither my 4g or wifi worked I thought it was Google's servers so I tried again this morning, same thing. (keep in mind at this point i think my phone isn't rooted anymore.) I call the t mobile store and they give me a technical support number, so I call it and I tell them i cant sign into Google. The gentleman told me he cant do anything because he can tell my phones been rooted. Only thing he suggests is to contact Google, well, the customer care number just tells you go to google.com/support and there's nothing there about my problem.
This is where I dig my hole even deeper. I tried another factory reset and up in the top left corner i still see that root text. Even the rooted android symbol pops up before the Samsung logo or t mobile. Since I saw that I thought "ohh it just didn't get unrooted all the way." I look up ways to completely remove a root and a lot of them require plugin your phone into the computer and using Odin to flash a stock firmware on to the device. I went to plug my phone into the usb port but my computer didn't recognize the usb device, having experienced this a long time ago I searched around for the latest Samsung usb drivers and I installed those. Device still isn't recognized. Let me just note before people tell me to use MTP mode or Developer tools> usb debugging or connection mode.. The only thing that happens when plugging my phone via usb is the phone starts charging and my computer makes the trumpet noise like something is plugged in. Other than that, there is NO notification of it being plugged in. The reason i stress this is because I called Samsung technical support at this point and the guy (not gentleman) treated me like a 5 year old and ran me through all of these options after i told him I already did everything he was suggesting, including downloading Samsung Kies 3 and having it install the drivers. It does not pick up the device either.. at this point I looked up ways to remove the root without the computer. I found out you can just go into the root app "SU" or something and theres a remove root option. I jumped on that opportunity and had it removed. I restarted the phone and all the problems still persist, it even still has the root text on the top left when you factory reset it again. However now, even if you factory reset and select the option "keep root," thinking it would bring back the"SU" app it does NOT.
So lets recap. I have a phone that thinks its rooted and even appears rooted to t mobile but doesn't have any of the root apps or privileges or capabilities to fix my Google log in issue (like the host file in filemanager). And I can't re-root to get that app back because none of my 3 usb ports, 3 different usb cables (one being the cord that came with the phone), or any of the ports/cables on someone else's computer will recognize the darn thing to work on that way! I have all these issues that are supposed to fix each other but I can't do any fixing because they cancel each other out too... I'm at a dead end.
In case this isn't the right forum/website/thread/post area etc.. I have this whole message saved in Microsoft Word document so I can repost it anywhere you guys might suggest better results. Any help/advice will be much appreciated.
