HI everyone
I am using 4.4.4 rooted galaxy alpha with developer mode on.
I have installed usb drivers supplied by samsung, despite many attempts my phones storage wont show up in My computer and because of that i am not able to transfer files to and fro from my phone.
Whenever i try to connect, a notification pops up in my PC saying USB device not recognised, however the phones seems to be charging.
also there is no notification on my phone relating to USB connection with my PC.
i have dchecked into settings and havent seen any menu inside relating to USB connections or Mass storage etc.
please help me with it thankyou
I had this problem a while ago. Turn debugging off and developer options. Then plug in the USB and turn dev/debugging back on. Worked for me
Nope, still not working. its still showing device not recognised
Do u have revoke debugging option?

Device not recognised.. didn't see that part.. right click my computer. Select manage.. uninstall the drivers you have for the phone.. then reboot. Reinstall Samsung drivers before plugging in the USB cable.. it should then install no problem
I had the exact same problem.
The problem comes from your usb cable, try with another one.

Code: *#0808#

No thats just incorrect user settings .
Remove cable go to settings Applications Turn on USB debugging .
And?or turn usb mass storage mode on via settings Wireless and network USB settings then connect cable .

Yup, I did. I removed cables and turned on USB debugging, and tried the mass storage mode, upon connecting it says cable connected and to remove.
I'm getting this problem once I'm in Download mode. It's worked before... why would it stop?
Any tips?
I have the same problem
I seem to have the same problem I connect my phone via USB and get a USB Device Not Recognized message but MTP application opens on the phone. This has only just happened I have had it working before since I had the phone on 2 computers and have tried to different cables now it does not work on either computer. If any one has had any luck I would love to know how you fixed it.
Samsung Galaxy S2 - USB Device not recognized.
Hey Guys,
I have the same problem. I've even tried going into "Recovery" Mode and then running odin.. Still no luck. It just does not recognize the phone.
I tried a different cable but still no luck.
Guys,
i had had the same problem until i started to use the original USB cable(came with the phone).
Have a good luck!

Got the same usb problem, different pc's, driver, cables nothing works.
After three month of use no Kies Odin ore mass storage us....big problem
any news info on this? seems to be quite common, though I only get it with stock roms, custom roms dont seem to have this issue
Cables Guy; I'm trying to figure out if I'm having the same problem as you. Does your phone charge when plugged in? Because mine does not.
i think in your case it might be the usb port in the phone itself, if nothing that you plug works well.
I believe there is an issue with kies/MTP and windows drivers for the rest though.
For me my phone doesnt get detected o nmy onboard USB but it does on the usb3 pccard i have.
any good news to solve this problems?
i got the same problem and worst case is my phone cannot detect sim
I had the same problem.. I just switched back to the original cable that came with the phone & problem was solved..

whats your phone kernel? and are u able to connect to pc as usb storage? or did u flash anything weird before?
Hi.
Just bought Galaxy Ace for my daughter and faced with the same problem. it's at official 2.3.3 firmware, and each time i connect it to PC via USB - it enables the USB debugging. I tried disabling it in Settings->Application->Development when phone is disconnected - no luck.
Strange, but i don't see a "USB connection" option in Settings->Wireless and networks... it's there on my Galaxy S thou... May it be an issue with Ace's official firmware?
Update: flashed VillainROM-1.0 and still having same problem.

There's only a "USB Debugging" option, which, being disabled, gets automatically enabled again each time i connect the phone to a USB cable.
So what is the problem if it's enable? And Ace don't have "USB connection" option in Settings
Sorry, I thought it's obvious: with USB debugging always enabled - I've no possibility to connect the phone to PC as a disk storage or to connect it to Kies/PC_Suite

NO, is not obvious. USB debuggins doesn't botter your usb connection at all since you hace to activate the disk storage after you connect your SGA. Look on status, there's a message that tells you that you have to click there to activate mass storage. And on the other hand, KIES recognizes SGA after a few minutes, just wait a little longer.
i have the same problem. mass storage only works if you have the samsung drivers installed. if you connect the phone to a different PC that dosent have the samsung drivers it will not recognize it. if you disable Debugging so that the computer would detect it as a mass storage, once you connect it, it automatically enables debugging again. if you disable it while connected, it goes back on automatically.
i'm running 2.2.6 but i've always had this problem since 2.2
using windows 7
anyone can help?
USB mass storage worked fine for me on multiple computers without the drivers installed and with debugging on. There is no reason why either of those things would influence your connection. The problem is far more likely to be with either your computers settings or your usb hardware.
i tried on a few different computers, same problem. i guess i'm stuck :/
thanks anyway

Phone not recognized by pc
I am running Cm7.2.0 RC3
menu>Settings>Applications>Development>android debugging (checked on)
I use this driver on my windows 7 pc (LGAndroidDriver_Ver_1.0_All) downloaded from Microsoft
I can,t remember exactly why but the I had to uninstall the driver supplied with the LG mobile update tool as it interfered what i was doing at the time.
I have to have debugging on and connect the cable to the PC first then the phone
the PC will recognize and the driver will display in device manager. The phone will display USB Connected and USB debuging connected.
I Hope this Helps! I have attached the driver press thanks if It helps and post the outcome, I will try to help as much as possible.

[GUIDE][CM9][HOW TO ESTABLISH - USB Mass Storage]
Since you've stated that the problem exists irrespective of the ROM you use, there is a possibility that your microUSB port of your phone might be damaged.
Also try and install the drivers on a different computer and see whether it's working or not. Also, if you can, borrow another LG P500, connect it to your system, and see whether it is working as it should. This will help in identifying where the problem actually is.
Hope this helps.
If their aint earthing in the socket u plug ur pc then congrats ur pcb of the phone has been damaged

Bro's I have a galaxy s3 32gb gt i9300 with stock 4.1.2. When I connect the phone to my laptop via usb (laptop is also Samsung) I hear a beep sound on the cellphone and it begins to charge. However, I see no options and no usb connected 3 pin symbol in the panel of phone and nor is there any other option like mount cellphone etc. I do have latest version of Kies installed on my laptop but even that shows no device connected. Please help guys I have spent a bunch of hrs trying to figure out how to get it going but eventually had to register on this forum for help :silly:
Tried a different cable? Usb uses fewer pins to charge than to connect to a pc. Perhaps the cable is damaged (or usb socket).

Much thanks for the quick reply.... No I don't think the port or the usb is damaged. Further, I'm using the stock usb cable provided with the phone. Any other suggestions?

And yes tried different usb cable, plugged it to different pc's, manually downloaded drivers from Samsung but still the dawn thing doesn't work
Edit: just now tried connecting a different cellphone using s3's usb cable on the same usb port and that works fine. So I guess that confirms both the cable and the port are fine
By port, I meant the one on your s3...
Check its clear. If it is, factory reset. If its still a problem, send for repair

I'm sorry for my quick scan on the thread if I miss something.
Maybe you should try go into recovery and mount USB in there to see what happens or try download mode as well (in this case, with download mode you can see whether USB works or not, if it works then means maybe problem with ROM, so you don't have to send to repair because software issue is not really a issue here, and if it doesn't, then download flash won't start so won't affect on your warranty for flash counts )

I had this problem before with a new brand cable, i just solved the problem buyin a usn charger for Cielo cards.
amazing.
Solved
I tried everything possible....
uninstall drivers. reboot laptop. install drivers. reboot laptop. plug in phone. no sucess.
put phone in download mode and plugged in. no success.
tried on different laptop running Windows 8 and Windows XP. Still no success.
Then i read about this somewhere...
said uninstall drivers. reboot laptop. install drivers. reboot. make sure USB debugging is OFF. Plug in phone. Switch ON USB debugging. Laptop should now detect the phone. But that didnt happen either. No success again.
Also read....
Go to phone dialer.... dial *#7284# to access PhoneUtil > "Qualcomm USB Settings" > set it to "MTP + ADB" .... phone will reboot. Then connect via USB and everything will be ok.
Unfortunately....
dialing *#7284# to access PhoneUtil did not show me Qualcomm USB setting.
It gave me 2 options:
UART> Modem or PDA (here Modem was selected for me by default)
and
USB> Modem or PDA (here Modem was selected for me by default)
I left UART as Modem itself.... but changed USB to PDA. Then click "SAVE and RESET" button.
My phone then rebooted. Once my phone rebooted and i was on lock screen/home screen.... i connected the USB to my phone and voila... my laptop detected my phone as GT-i9300 and show both my SDcard and extCard :good:
Give it a shot and lemme know....
I have same problem. I tried 3 diferent usb cables, two original, 3 computers and nothing. I used MTP few days ago and now nothing in options, just cahrge. I tried factory reset, clean cache, usb debuging on/of, in download mode too... Reinstaled Kies and drivers. I cleaned usb but still nothing. I tried secret code but not have option ADB+MTP. Any help? Sory for my english

Does #*7284# give you the following:
------—-—-------------
UART
-Modem <--- selected by default
-PDA
USB
-modem
-PDA <--- selected by default
???
If under USB, modem is selected by default, then change and select PDA.
Leave UART value to remain as modem itself. No charge here
Or worse comes to worse...
While keeping phone connected to laptop, enable USB debugging and see what happens.

So at the moment your PhoneUtil settings are UART>Modem and USB>PDA right? Leave it at this setting.
Now with the phone connected to you computer... Go to device manager and Uninstall any Samsung drivers that u would see in Device Manager (Windows). If you see anything like adb drivers then also Uninstall. If you have any other phone drivers (Nexus, LG etc), Uninstall those as well. Also from Control Panel>Uninstall a Program, Uninstall any USB drivers programs that u would see in the list.
Once u are certain you have Uninstalled all phone & adb USB drivers. Also Uninstall Kies completely. You might also need to disable Windows auto driver installer. Reboot ur laptop / computer.
Once computer reboots... Google for Samsung USB drivers for mobile phone. The version I used was v1.5.27. You can try with any version. Some people have had the best luck with v1.4.60. Install the drivers and reboot the system again.
Switch off ur phone. And go to download mode.
Then connect ur phone to the computer via USB cable and see what happens? Look in Device Manager again and see what is showing. Also try using a USB 2.0 port for best results.
Once done... Unplug the phone... Get out of download mode.... (u can simply put the battery out of the phone)... Or long press the power button... Let the phone restart. Plug the phone again to the computer and see what happens?

These are the only things I can suggest.
If all fails then your only option would be to download "Airdroid" from Play store.
It will not solve your issue but will let you transfer files to your phone at least

while saving after selecting SUB -> PDA, phone should boot automatically.
but my phone resets the both options to MODEM. I dunno why.
Recently updated from WinXP to Windows 7. I am having trouble with the USB drivers for my phone. The phone charges, but my phone does not show it to connect in the pull down menu. I can't use it as a USB drive. I cannot tell that the PC recognizes the phone as being plugged in.
I've installed, uninstalled, and reinstalled Kies multiple times. I've installed the USB drivers that come with Kies. I've downloaded the drivers and installed them separately(with Kies installed and not-installed). The most recent drivers I found were 1.5.45.
I've tried turning the Debugging off and on.
With WinXP, I often needed to reboot or uninstall Kies to get the program to work. Frustrating, but it worked. Now, it won't.

I can't connect my phone to my PC, so can't install apps from my PC.
Other USB drives connect to my PC fine.
Well, that got me thinking about the PC, and I reinstalled the VIA USB drivers(as compared to the Samsung ones). It now recognizes my phone. Whether I can get Kies to convert video is another question.
