Not sure when it began but I am unable to connect my tab to any pc. I have tried 4 different ones. It just gives me the error message "usb device not recognized". I have the custom rom from overcome(the latest one) installed. I put the tab in download mode and the same issue remains. I turned on/off usb debugging and it still doesnt work. I even tried the *#7284#. That did not help either. Please help.
Hi..firstly, welcome to XDA Samsung Tablet Forum. I see you already register since Nov 10 but your post so far is only 2 post. So I'm consider you are still newbie (same like me
Anyway, back to your question.
Have you go to samsung webpage and download the kies?
http://www.samsung.com/my/support/d...WDXME&prd_mdl_name=GT-P1000&srchword=GT-P1000
Do that first, after install it, go to >>Tools>>Install driver. Click it.
make sure your tab is connected to your PC via USB.
After you click the install driver, kies will download the driver for you and it will automatically detect your USB tab.
please try.
Is your pc windows xp or 7? W7 doesnt need any drivers installed, but W xp needs drivers.

Sounds like a fault with windows. Try running updates or use a registry cleaner/fixer see if that helps.
CCleaner has one.
[EDIT] Ah I misread, looks like you have tried other systems with same issue. Not sure then.
I'm assuming you're not using the same cable with all of them, otherwise you'd want to try a different cable. If you've tried the different cables between the different devices and still the same issue, you might roll one of them back to stock and see if that fixes the issue or not. It's possible you have bad usb ports, but more than likely it's a software issue on the tab.

How about the usb cable? Possibility is high due to cable itself. Since you using the same cable with all PC. You should try to change it.

Bad cable or bad tab. Borrow a cable to eliminate that.
Not sure, When i was reading instruction for how to update with overcome rom it said that if Odin doesnt recognise the tab try a different USB port.
Hi everybody,
I installed the drivers manually but still I get the pop up of "USB Device not recognized".
I installed the drivers named as "LGUnitedMobileDriver_S498CA21_WHQL_ML_Ver_2.1".

And same as mgregor, don't use front panel to connect USB.
Used drivers must be obsolete. Use 3.2.1 or 3.5 and be sure android platform modem is activated to be recognized by b2c
Try LG United Mobile Driver, there is a link on knzo's CWM recovery thread. And yes try a direct port on motherboard behind your cpu case.
Also try another usb cable.

at this problem.... in my opinion is to check your usb cable or the usb port of your mobile...
if you cannot open the mobile,you can go to a mobile technician and tell him to resolder the usb port of your LG optimus....
My pc is a notebook.
Firstly thanks a lot.

It seems a bit risky my friend... I don't know what to do. Can I root my device without connecting to pc?? I want nova. Previously I rooted my wildfire with CM7. It was very different!
Be sure platform modem is activated in peripherals manager. This is what makes the phone being recognized by pc suite and b2c

It is activated but when I try to update driver it can not find any. Which driver should I use at that point? Maybe there is a problem in the connection point on the phone?? I am not use about taking my optimus to a mechanic.
Do you have another computer to test? Perhaps the problem was related to your Wind0w$ system...

Use WiFi, open forum and search GingerBreak, download and install it.
If your ROM are V10A, then it should work..

I tried to connect my phone to an other XP result is the same "USB device not recognized". I tried Windows 7, Windows 7 did not even pop-up! Nothing happened! Only my phone was charging.
I am looking for gingerbreak but this problem is very annoying for transfering files. Each time I have to remove the SD card... Or myphoneexplorer(connected by wireless)...
Any advice?
Hi guys,
I finally managed to connect my phone to my pc. The problem was about the cables that I tried. Another original lg cable solved my problem.
But now I have an other problem. The brightness of my screen. It is usually at the minimum brightness and I can't change it. It does not change anything when I change the brightness settings. I tried other firmwares from http://luivit.altervista.org/firmwareP970/index.php but did not work still the same!

hi everyone . i have question Is there any way to connect samsung mini to pc without installing bunch of samsung usb drivers? i heard once that there was software which comes for rooted phone that will make ur device that wont need usb drivers installed on pc!!.. im sick of this issue due to i just switched from nokia to samsung and this problem is annoying for me(and im sure for everyone). nokia didn't have this problem!! help someone.
You have to have some kind of drivers. Just download kies and install it, then try to connect your device and the drivers are installed. I saw windows downloading some drivers when I first connected it but idk...
Its one time installation and you don't need to do it again.
Edit: I'm sure nokia had drivers too. They were installed with the pc software.
Nokia supports plug n play on all platforms. But Android supports plug n play only in Linux as Android is Linux. To enable plug n play in windows u need adb(which u call drivers).. Isn't that simple to understand?
Not true. Plug and play doesn't mean that it doesn't need the drivers. Actually, my gf's nokia e75 took about 1.5 hours to install drivers, even after installing the pc platform. Point is, the pc needs them to communicate with your device. So, wait once for them to install, and then you are done gor as long that you use this pc, or this mobile device.
But, it might be usefull to install kies from the samsung website... It has a driver package with it. Could speed up the process

Do u even know what plug n play means?
its impossible to install drivers/sam kies on every computer that i want to connect! coz some times i maybe wish to connect my phone to office pc or cafe etc that i didn't actually have admin access to install drivers/kies ,,yeah Linux os didn't ask for drivers.

Do you want to transfer files between computers and your device?
Did you get a micro sd adapter with the phone?
If yes, buy some card reader and plug it in every computer you want.
install kies in ur pc and after finishing go to the installation directory and there u will find a folder named driver/usb driver.go to the folder and just preserve the file. u can now uninstall kies and from now on u will have to just install the driver file that u extracted from the kies. by this way mini will be connected to ur pc without kies installed.

Well probably u don't know. I won't give any explanation. For the mini to work directly on any pc, u can try pairing it with bluetooth if the pc has one or there is another way which I currently don't remember. Sony xperia phones does not need any drivers, they have an inbuilt app which does the work. If anyone could find out what that app is then the problem is solved. I think its something like 'sync'
Don't remember.

I connect my galaxy mini to any PC i want by turnin on the USB storage mode. We can Transfer files without any card reader or drivers. Only glitch is no access to contacts or inbox but who cares!
Here's how u do it, goto settings->applications->development->enable USB DEBUGGING
Then connect ya phone from data cable, u'll see a usb icon on notification bar click on it n TURN ON USB STORAGE
Simple right?!
P.S:If u don't see a USB icon in notification then enable usb debuggin once again from settings.

That app doesn't seem to support windows 7. My brother in law tried to port it to LG optimus, and to my galaxy mini, but it won't work proper. But, you can always trie to get an app that works with microsoft activesync. That's embedded within windows, so the drivers for that should be found and install fairly quick.

Hi mate, follow my method
PLUG IN your USB CABLE through behind of your CPU (do not jack your phone 1st)
goto SETTING-APPLICATION-DEVELOPMENT, and UNtick "USB DEBUGGING"
Jack on your USB CABLE, okay, now you will noticed "USB PROMPT" . slide down bar and choose USB DEBUGGING (copy files etc bla bla bla it says) and TURN ON USB STORAGE . you're DONE
http://www.4shared.com/get/RsWcxNuH/samsung_usb_driver_for_mobile_.html
Try this file if you don't wanna install Kies and still wanna connect your phone to pc....
install pdanet on pc and while doing steps on it you will need to connect your mobile to pc with debugging enabled and driver will be installed
Plug and play doesn't mean drivers are not there
crazy_k_p said:

Plug and play simply means that the drivers are automatically installed as soon as the device is connected.
There is not a single piece of hardware that "does not require drivers" to run as far as i can tell.
Drivers are always required, but u dont need to install them manually in case of plug and play devices.

Hi, guys! I have a really big problem :/. Right now I'm using the stock 2.3.4 gingerbread from LG ,but you all know that this is the worst OS ever. I wanted to get rid of it but i cant connect my device to the computer. It's only charging. I need a way to root it w/o usb connection. Do u have any suggestions? It's not a software problem! Something inside the phone is broken and i don't know what it is. Is there a way to root it via bluetooth or SD card? I didn't find any apps to root it too. I know gingerbreak etc, but they dont work for 2.3.4. Thank you in advance and i hope there is a solution. :fingers-crossed:
I am afraid you can't. Replacing your micro usb port could solve your problem. I reccomend to buy a micro usb port which is already on the flexible cable so you can avoid ironing.

i forgot how the mass storage settings in gingerbread look like but there should be an option to put the phone in "charge only" mode (which you should disable)... pressing menu key in settings > storage doesn't give you any options to choose?
In gingerbread you can only turn usb mass storage and usb debugging on/off. These settings didn't help. I'll read more about the first link you gave me and try it out.

This is quite challenge, root without usb connection. First idea I got to use ADB over WiFi, but this is available from ICS, not on GB.
Second idea - what I remember, some of root methods use APK installation over ADB by script. Maybe you can search for these script methods and place all required files on SD Card. Then try to execute commands by terminal on device itself to install and root.
It's just my idea, maybe wrong, maybe help.

Yes that is what you need if you have to replace your USB port but you don't have skills to replace only the usb port.
You can try gingerbreak to root your phone, but it maybe won't work.

if you read the 1st post, you might find out how could it help you... especially if you use win 8 which caused problems for many other users when trying to install the drivers or trying to flash the phone...
I - Install APX (NVFlash Recovery) Drivers if not already installed.
It starts the windows device driver wizard to help you install the drivers needed for NVFlash. It detects your system OS and gives additional on-screen instructions needed if your PC is running Windows 8.
FYI: The drivers are located under ToolKitFiles\nvflash\driver folder.

Your device does show up in the device manager, so that's a good sign! Can you see what the exclamation mark means in the properties?
Same problem here...
Tried with another P880 on same computer and it was found.
ADB works, and access to SD-cards (internal/external) works just fine.
Only thing that doesn't work is PC Suite, it just doesn't find the rooted device.
