It all started when my phone didnt connect to the pc with my own microusb cable anymore. After lots of reinstalling drivers i tried another usb port, now the phone did connect. In a rush i started up odin to flash standard firmware so i could get my warranty for the usb failure. Then during the flash the phone lost connection again and hardbricked. I can only get it to download mode but the phone has the usb problems mentioned before again, i cant connect to odin/kies/pc. all pc's told me that the usb driver could not be installed
try removing all usb drivers with usbdeview, make sure that KIES aint running in the background, boot phone into downloadmode, connect is and as soon as you'll see the yellow com-port sign; hit start (with the proper .tar files at pda/phone/csc).
only one way to find out =/
Thanks for the help but the problem is that the yellow com-port sign wont come because the device isn't recognized.
You have download mode but no USB .
Remove existing KIES and all USB drivers reboot reinstall KIES and try .
Not work try on a different PC .
But unless you have fixed the initial error you are wasting your time .
Initial Error you said >>>It all started when my phone didnt connect to the pc with my own >>>>> microusb cable <<<<<<<<<<<<< anymore

Tried another cable and another computer, still no connection. I think probably an internal failure in the phones motherboard?

3 days ago i flashed my sgs with Ultibread v1.3
Today i decided to flash back 2.2.1 firmware, but all of my 3 computers (10 usb ports) couldn't recognize my phone.
Try to search any solve of this problem, but no one tutorial has not helped.
What did i do?
uninstall all of samsung usb drivers
clean register of all garbage with "samsung"
reboot my computer 3 times
download latest samsung usb drivers v1.3.2000.0 (25.jan.2011)
get out battery for 15 minutes
try plug in other usb port
take computer, wich never connected my phone, install latest drivers (see previous step) and connect sgs to him...
In all cases, the result is one: Unknown USB Device.
System can load and "debug mode" switched on.
Please, help me...
My PC forgets my SGS on a regular basis. When I plug the USB into my phone it is usually a good 50/50 if it recognizes it.
I have found the best way to deal with it is to reboot the phone while it is still connected by USB to the PC. When the phone comes back up with the USB connected, the PC always discovers it right away.
Also avoid connected through a USB hub if possible, that always gives me trouble.
Omg! Solved.
Ultibread v1.3 and, maybe, 1.4 got issue with check in debug usb mode.
And without this check - windows can't recognize phone.
Solution:
turn on debug usb mode in settings, then put out battery when phone is ON.
Then you can get in download mode.
Case closed
Hello
I have Froyo 2.2 I9000JXJPB
I used to be able to connect to PC but not any more. Im using Windows 7 64
I even tried and restored my laptop for factory condition and wiped out my galaxy.
Sometime when I connect the phone with the usb cable and PC would say unrecognized peripheral device and most of the times nothing happenes
it does not help if USB debug is checked or not
I even tried different usb ports in the laptop but nothing work
its driving me crazy
need help please
ok, put the phone in download mode and then connect it, try a USB port that connects direct to the motherboard, usually at the back of the tower.
also if that fails, try to uninstall kies and then re install it, that will re install the drivers.
then post back with the result.
EDIT: just realised your on a laptop not pc

Before postig my question I tired uninstalling and reinstalling kies. also tried driver reinstall option from kies
I downloaded the driver separately tried installing several times but it did not help...
Installation always endup with a message Device driver was not successfully installed
Unknown device device unplugged
Unindentified device device unplugged
If i recall correctly my problems maybe was with the last update with kies
if you go into computer > device manager and then select on the 'unidentified driver' you can select uninstall.
then start the process again, and also try installing it for the 2nd time with a different port.
Hi all,
I have a huge problem. I dont have USB mode anymore. When I plug the phone to my PC, it doesnt ask me if I want to connect it as a storage mass. It is only charging; windows doesnt recognize a new device too, so I cant use nvflash.
Besides, I dont have the recovery mode, I cant use it to install an previous rom...
Can you help me please ?
I have the same problem on my G2x after flashing ClockWorkMod...
I had the same problem. I asked the retailer for an exchange. However, just before I returned it, the phone was plugged in to my laptop USB for charging and all of a sudden there was a notification saying that USB was connected. I had done a factory reset before this but it hadn't helped.
You could try enabling Hidden Menus and then in Port Settings try changing from AP USB to CP USB and see if it helps.
Also, try reinstalling the drivers on your computer.
Hello, my Samsung Galaxy S GT-i9003 was working fine yesterday, but now it stays stuck on the samsung logo when booting. I'm trying to flash it, the thing is, I can't get my computer to detect my phone, it shows up as an unkown device. I tried a factory reboot etc.. didn't work, and I can't even use it as a mass storage device since it's bricked. I used all the newest drivers, the newest version of kies but it still doesn't work.
I'm on windows 7/64 bit btw.
Thank you in advance.
Are you able to enter into download mode? (hold volume down + home + power)
If not, You can try to make (or buy) a JIG which will force download mode and you can flash a new ROM with Odin
Regards
I can enter in download mode, the thing is, my computer detects my phone as an "unknown device" and it isn't recognised by Odin either, which means I can't flash it.
are you sure the drivers are installed correctly? I recently had problems with the USB cable.. try another one and if possible, other PC....
I installed many times the drivers, using kies or without kies, the result is just the same, maybe it's the cable.
Try to change the cable and the USB port. Last week I tried to update a Motorola Atrix and the same thing happened, unknown device. Then I changed the USB Cable and voila... worked !
Let me know if it works....
Regards
just wondering if you have resolved this yet ? I have same problem tried all usb drivers i can find , 5 different computers , jig , odin still not detect and windows show unknown device detected.

Guys I had the same problem. After trying many pc, drivers, cables combinations I came to a conclusion that the usb port on the phone itself must be damaged. After taking a close look, I saw some of the gold contacts damaged/missing.. That might be the case with your phone aswell. Look at the pins and if yo usee some visual damage you know what the problem is. Even if you dont see it, it still might be a problem.
Ok So was running my custom rom and decided to return it to stock. PC odin keeps saying fail when I try to flash standard ICS Rom and then whenever I try to retry it my PC keeps saying USB Device is not recognized?? I uninstalled Samsung Kies and Samsung USB driver and reinstalled but still have the same problem?
My phone can get into download mode and also if I simply try to turn it on its says Firmware Upgrade encountered an issue, Please select recovery mode and try in Kies & try again.
The standard rom I am trying to flash is called: N7000XXLQ2_N7000XXLPT_N7000XEULP4_HOME.tar.md5
And the version of PC Odin is Odin3 v3.04
Can anyone help as I am stuk at work without a phone
Forgot to say when I put it in download mode and connect the usb cable I get a pop up on my pc saying USB Device is not recognized.
it is due to bad usb connection
1 change usb cable.. may b it getting shorting inside ,, on rx tx
2 change usb port. do not relay on front cabinate usb if you are not using laptop.. use on board usb
after this two things should change or your motherboard is not producing enough power for device
try on another pc.. ofcourse of frend..
regards
