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.

Does anyone know why the Found New Hardware Wizard keeps popping up every time I connect my Tipo with USB?
~~~~
Windows XP is always looking for some other driver and I have no idea where to get it.
* I am running Service Pack 3.
* I am using a standard MicroUSB cable that works fine with other phones; nothing fancy.
* I have tried various things I won't bore you with. I am looking for a real solution now.
I have never been this frustrated for drivers before.
Device Manager
Device manager's Other Devices heading simply shows Android underneath it, with an exclamation mark next to it. Obviously can't find the driver for something in the phone.
I would have thought Sony PC Companion would fix the driver issue, but that seems to logical; it doesn't.
Yet the phone works fine in PC Companion (detected perfectly).
Yet still this Found New Hardware Wizard keeps popping up every time I connect it.
I have seen other references to this on Google but haven't been able to find a real solution.
Help?
I found out the problem:
It only happens when USB debugging is enabled on the phone.
Weird thing is I tried the Android SDK drivers and it would still be looking for something it can't find.
I turned USB debugging off and all is good again.
But that's still annoying when it's enabled.
If anyone has any other insights, I'm all ears.
finally rooted
OK, just writing this down in case it helps someone.
Because I almost got admitted to the insane asylum figuring how to root my Sony Tipo Dual.
Say you want to root your phone and you don't know what's going on with drivers, like I didn't above.
And say PC Companion is not helping at all, like happened to me above.
PC Companion will detect the phone but the annoying Found New Hardware thing would always come up when you had USB debugging enabled in the phone.
And say you don't know a thing about ADB drivers or where to get them, like I didn't above. And say you literally spent days trying different drivers from the net and from the Android SDK, none of which worked for the rooting task, all the while trying to root the phone with various versions of Bin4ry's tool on and off over the last few months.
And say you've gone through hundreds of searches to find the answer to basic questions about rooting and all you've done so far is unlocked the bootloader, like I already did. Which in itself needed some extra help due to poor instructions.
The fix
Well, what I did was this, and I'm still not sure which one triggered the fix...that's how dazed and confused and surprised I am.
I installed Sony Update Service (free download on their website).
This did't seem to fix my "Found New Hardware" pain. At least not yet. PC Companion would still detect the phone normally and outside of this I would get no action with Bin4ry's rooting tool.
Then I disconnected my phone from the PC. This time I tried to uninstall some stuff.
I uninstalled PC Companion. Rebooting after uninstallation.
Then I reinstalled PC Companion with no phone connected. Rebooting after installation.
Then I connected the phone while PC Companion was running. Traditionally I'd close PC Companion down entirely before running Bin4ry's rooting tool and I'd get nowhere.
This time I started Bin4ry's rooting batch file (version 18) while PC Companion was running. Now it was working! So PC Companion needs to be running when I do this? I thought I would just get the driver loaded automagically and I'd be on my way. But apparently it needs to be running?
My god, some new green text that never showed up before while using Bin4ry's batch file!
My god, a message on my phone to respond to, coming from Bin4ry's rooting tool!
The rooting process was working!
Just like that. The phone was rooted. Just a bit past midnight.
I was on the edge of insanity wondering how to root the thing and then it all happened.
Last night was spent grabbing an app to help me delete so many services (nearly all Google apps/services deleted, and Facebook, and Sony's fluff, etc) from the phone. The phone is finally being cleansed of corporate spyware and I can finally run apps that only work on rooted phones like Droidwall and others I've yet to try.
What a great feeling!
Hooray. I finally rooted the thing.
Hope it helps someone.
Hello everyone,
First and foremost, please forgive me if an answer to this has already been posted somewhere; I have searched several different forums extensively, and while I have found several similar problems, I have tried their solutions and come up empty-handed. Here's my dilemma:
1. My phone simply refuses to be detected/recognized by my PC via USB connection, through Kies/Odin/Windows Explorer, though I can be detected and connect through AirDroid.
2. I have updated my Samsung USB Drivers for Mobile Phones, and reinstalled those drivers multiple times.
3. I have tried multiple different USB cords, as well as multiple different USB ports.
4. I have been successful in connecting my wife's Note 1 to my PC.
5. I have tried dialing the "*#0808#" code into the dialer, and it always tells me that the signal is weak.
6. I have done a factory reset, both through the settings menu and through the recovery mode.
7. After having done the factory reset, I have been able to get the phone to download updates, but when the phone tries to install them, it only gets to 25% every time and then shows "Error", after which it tells me that the firmware was unable to update.
8. I have downloaded, installed, and tried every app I can find that claims to be able to root a phone without a PC, and they have all failed.
9. I am simply unable to find the "USB Connections" menu, the one where the MTP or PTP modes are, and have only been able to access it through Samsung's "Smart Care" app.
10. I have also tried to get Odin to recognize my phone by resetting my SIM card, and by using the battery removal trick: neither worked for me.
I think that pretty much covers everything right now.... I am COMPLETELY dumbfounded, and have NO idea what to do, NOR do I have any idea if this is a hardware or software problem. ANY help would be MOST appreciated.
Hi,
You have already made a post here on same topic. Please do not make multiple posts of same topic. kindly wait for the experts to answer your question.
Thread Closed.
Ok, so I have someone's Kyocera Kona S2151 flip phone. Now when I plug it into my pc in device manager there shows two "modems" and a serial port without a driver. Even after installing the specific driver for this phone from the Kyocera website it still says there is no driver. I tried to manually select the driver from the folder that was created during the install, not a single one of the 6 worked. Now all of this might even be a moot point as I don't even know if this device will allow me to pull the pictures off of it using a USB cable attached to a pc and everything on the web says I should be able to but there's also a Kona android smart version. I also can't find anything that says I can't either lol. Now I would Bluetooth but there are no options for sending photos via Bluetooth and whats worse is the antennae for the cell service is going out so it won't stay connected to the tower (I assume its the antennae, I'm not gonna try and fix something this old, also its sprint which just got absorbed by Tmobile which could also be the issue bc its pre sim card).
So, in summary, I am trying to retrieve the photos. You can't Bluetooth them, there's no SD card slot, I can't text or email them due to lack of wifi and cell service issues, Which leads to the only option left, PC USB transfer but I can't get that working either due to what I am hoping is simply driver issues. If I need to use an older Operating system that's fine I have another pc here I can mess with to my heart's desire.
I know this isn't android, rooting, modding, custom os, related but this forum is home to some of the smartest people, it's where I come to get all my instructions and files for phones. if anyone could help I'm hoping it's the community here.
Oops, just saw the "don't post questions here" my bad... sry
Update, I installed xp on an older pc I had sitting around. ALL drivers worked fine BUT it appears the only functionality this phone would have for a pc is to act as a modem. There doesn't seem to be ANY functionality in the way of file browsing or retrieving media. Furthermore, this specific phone lacks media sharing over any other connection aside from the mobile network. So if anyone has one of these old phones and it no longer has service/can no longer connect to towers your only option is going to be a data retrieval company.
Bummer, some older phones are very limited when it comes to retrieval. cheers

It seems that now the only way is to have the driver work and then use PC USB transfer. In addition to the driver from the Kyocera website, have you tried the Google Android USB Driver for Windows? It's available on the Android Developer website. Have a try. Good luck to you.
Flip phone, not an anroid
