Theres a setting for usb conn that will let you use it as an ext drive and other options. I doins id i change the default to external drive or mass storage i think they call it you can uae the phone while charging.
You can set thay as default or have it make you select eaxh time

Good to know. I ended up plugging the charger to the wall and did it that way today, because of this.
Although I just looked through settings, and can't find it. Must be buried somewhere.

Helpful Help
Hey there...to better help you with this problem (as I had the exact same problem and it really pissed me off):
1. Go to "Settings"
2. Go to "Applications"
3. Got to "USB Settings"
4. Select "Ask on Connection"
I have no idea what "Samsung Kies" does other than drive a person crazy...anyone out there know what that does?
I have a feeling AT&T are gonna get calls about this...

ummm, that'd prolly clear my problem up, but would take too much time getting everything reinstalled and reconfigured. Phone's fully functional as far as I can tell, just USB Debugging setting is greyed out. Any ideas other than a factory reset?

heh, figured it out. Thanks, XDA...
anyhoo, seems USB Debugging is greyed out *if* USB is set to Ask on Connect. Set to Mass Storage and USB Debugging is available...

I just got a replacement handset and now I am unable to enter into usb debugging mode. I can select it but as soon as I exit the screen it becomes unselected. I have also tried to select mass storage instead Ask on Connect but it won't let me do that either. Every time I try to select another option I am bumped of the screen. What is going on here?
By the way I have a Samsung Galaxy S 4G. This doesn't make any sense other than T-Mobile disabled this feature.

It would make more sense to ask at the SGS4G forum.

[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?

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.

USB to PC - Folder availability changed

Sorry if this is a stupid question, most of my search resulted in threads about mass storage protocol vs. media transfer protocol, which isn't my issue.
When I first bought my TF300T, I was able to access most, if not all, the folders on the TF300T from my computer when connected by USB. This was not mass storage protocol, it was media transfer protocol as well, but I had full access.
After a hard reset, my PC only recognizes the tablet as if it was a camera (or an iPhone), as in I can only access the DCIM folder and only to download the pictures.
Something changed either in the TF300T settings from the reset (never upgrade to 4.2, I am still at JB 4.1), or I changed the drivers on the computer.
Anybody knows what I am talking about?

you're on stock now right? and what OS are you using on your pc?

In Settings -> Storage -> USB Computer Connection, just change the connection type from PTP to MTP.

I've been looking in there several times before and never saw the option but since you told me it's there, I went to look and stare at it... until I saw the 3 little square on the top right corner, completely out of the way
Thanks!
But next time, specify that it isn't right in front of you when opening settings - Storage

To be honest, the TF300T is my first android, which I owned for 4 months, out of which 2 months it was broken (waited a month before getting around to order a digitizer and took a month to receive), and the 2 first months I gave it to my son since he was going on a long long travel trip.
I only got to know the device for a few hours, and get "intimate" with it when I had to swap the digitizer

[Q] "Allow USB Debugging?" Keeps Popping Up!

After upgrading to 4.3 on my i535 GS3, I'm now faced with a very annoying new problem. I use easytether pro to tether to my macbook, and now when I plug in the usb it pops up with "Allow USB Debugging?" followed by my computer's RSA key fingerprint, and then a checkbox for "Always allow from this computer".
It doesn't matter if I check the "always allow" because the next time I plug it in, it pops up with the same message again. For some reason it's not recognizing my computer, even though the RSA key fingerprint is exactly the same every time. Even worse, I have to go through this process twice every single time I plug in my usb - once for the usb connected as an installer, and twice when it switches from installer to media device.
I use tethering quite a bit, so this is kind of grinding my gears! Does anybody know what might be going on here? Is it possibly just a mac thing? Perhaps something wrong with my settings?

Try this, In developer options ->root access - allow apps and adb also USB debugging notify is unchecked.

I don't seem to have any "root access" options in my developer options. Is it hidden or something?

Sorry I must be half sleeping and thinking about custom ROM. You don't have that option, anyway do you still have the messag after untick the notify option?

You mean leave the "Always allow from this computer" unticked? I've tried both ways...it always comes back. It wouldn't be a big deal if it wasn't for the face that the connection is blocked until I hit the ok button, twice around.

Still having the issue. It's starting to grind my gears...
I nobody else having this issue?

I just started having this issue and am investigating it. If I had to guess, I'd say the rsa key store is corrupt, but I'm just guessing. It was working fine this morning, and this afternoon it started yelling at me repeatedly.
I'm going to grab a logcat then will post back if/how I fixed it.
EDIT: turns out my issue was a bad USB cable. well, a bad USB cable connection. unplugged and reseated the cable and it seems to be working now.

I am also having this issue with two devices out of three I tried.
Samsung Note 10.1 (SM-P600) running Android 4.3 and ASUS K011 (ME181CX) running Android 4.4.2 always asks for permission. I tried everything including using different cables, different usb slots, different adb.exe. Even tried rooting K011, but no luck.
However, I am not having this issue with Sony Ericsson Xperia Arc (LT15i) running 4.0.4.
Edit: I came here from Google and now noticed that this is Galaxy S III section, but I think the reason to this issue and the solution will be the same. I will post the solution to here if I can do it.
---------- Post added at 03:21 PM ---------- Previous post was at 02:21 PM ----------
Yeah, solved it. I first killed adb.exe then simply deleted the folder C:\Users\Username\.android. After that I plugged my device in and typed "adb devices". This changed the RSA key etc. It asked for the permission again and "Always allow" option worked this time.
This method worked on both ASUS and Samsung. Hope this works for you too.
Note: I recommend you backup that folder before deleting it. Or just move it into another folder.

Mac computer
I'm having this issue with easy tether 1.1.12 in a mac (currently running OS X Yosemite 10.10.3) the windows keeps showing everytime I plug the device. Does anyone experience this on a mac computer?
In a windows 7 PC it works perfectly, no messages at all after clicking the "remember" box.
