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

Download and install these on your pc/laptop , your problem will be fixed

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.
Okay a little backstory:
I was on an early version of CM9 but as i am selling the phone i decided to put a more stable version of it on there and downloaded CM7 -stable.
I flashed this in CWM and it worked fine.
I gave it a quick test and noticed all the google apps were missing, most importantly the market. So i booted into recovery and realised i had forgotten to put the zip on the SD card.
I then went into mounts and mounted USB, nothing happened...
From that point onwards the phone would not talk to the PC. even if i booted up into the phone, it would just show it as charging. I could not find any options in the menus for USB options.
After some extensive reading, i tried a few things, none of them had worked. I found a post mentioning some kernels have issues with USB, so i downloaded the recommended one and flashed it in CWM.
After rebooting, CWM was now orange and not blue and the option to flash from external card has gone.
I have also done some digging and there is a good posibility that the kernal that i flashed was for the GT I9000 (which is the american one, right?)
So as it is at the moment:-
I can get into CWM.
I can get into download mode through the 3 button combo.
I can get into download mode using home made jig.
I can boot the phone, but it boot loops.
I can not get the phone to be detected on the pc.
Things i have checked:
Cable will connect other phones.
Tried different cable to be sure.
Phone used to be detected, but downloaded drivers through kies again to be sure.
Closed Kies using task manager.
Nothing is coming up in network connections in device manager when phone is connected.
I'm out of ideas now, so £10 PayPal donation for anyone that comes up with the solution to fix it
If i can get it detected, i can use Odin to flash what i want.
Sounds like a drivers problem. You may need the 'Google driver' developer.android.com/sdk/win-usb.html
When I had bootloops when I first installed CM9 I used heimdall to flash a the stock CM9 kernel. This gave me back CWM.
heimdall flash --kernel 'kernel.zip'
In the commandline.
Thanks for that,
I already had the Google USB drivers from when i installed the SDK to make some apps.
So i then gave Heimdall a try (Graphical Version), it seemed to suffer the same problem.
Reporting "Failed to detect compatible download-mode device."
I seem to remember the GUI saying I didn't have the correct drivers and it downloaded them for me.
The other thing worth a try is changing the USB port and reinstalling the correct drivers on that port.
I've not seen anything like that, it has not asked me for any drivers.
It's like the phone is not connected at all. nothing will detect it, i have even tried it on another PC.
Sorry, I'm not sure what you mean by installing on a port.
Well sometimes changing USB port will allow you to install new drivers. Although if you've tried it in another computer and it doesn't work then changing port may not help.
Does the phone appear in device manager when it's connected and in download mode?
Nope. Not coming up at all in the device manager. It didn't when it was booting fine. And it still doesn't in download mode. :-( I'm thinking the usb connector on the phone might be faulty.
But it was working up until trying to mount the USB in CWM

I don't suppose you have access to a Linux PC do you? Windows USB drivers are notoriously sucky. If you could plug it into a Linux PC and type 'lsusb' at a command line, that would at least show you that the device is really there.
I think I have a spare pc kicking around that I could use. I'll give it a go when I get home tonight.

Remove all the drivers completely from device manager for Samsung, then install fresh drivers and connect the cable when in download mode, hopefully it will recognize it
Are you sure the connector is clean? e.g. maybe there's dust in it.
I had that problem once, the connector was full of fabric fibers from some coat's pocket I had the phone in.
Suggestion 1 (Linux): I installed ubuntu, did not detected anything to even install any drivers. Detected my new phone fine.
Suggestion 2 (Uninstall drivers from device manager): I could not find any drivers named with the name Samsung in there.
Suggestion 3 (Clean port): I have some compressed air that i sprayed inside, it does look pretty clean and will continue to charge but still not connection on the pc.
To install the drivers for heimdall you have to run zdiag from inside the driver folder. Had to do this earlier on, the phone the other appeared as something other than Samsung composite usb or whatever it normally says
I tried this, and it displayed 9 devices after selecting show all. I seemed to recognise all of the items in the menu.
To be sure, I then disconnected the phone and re ran it to see if one of the items were missing, but it was the same number.
I too had problem with the usb connection on my i9000, and I was pretty sure my usb connector on the phone is somewhat damaged since it sometimes can only go to charging mode without being detected by my pc as a usb device. CWM instal is fine but ODIN can only detect the phone without able to flash the rom to the phone. The flashing will always stuck at the message "Setting Up Connection", I waited for 15 minutes and the flashing will eventually died. I retry the odin flash for 40 to 50 times and eventually the flashing will go through one time. Tried heidmall command line and the result is the same.
I have problem with Odin in the past. I bought a new laptop, running Win7 64 bit. Installed Samsung Kies to install the correct USB drivers for the phone. Then made sure that Kies wasn't running in the background. So tried using Odin. Odin was detecting the phone, but it was hanging at initialising connection. Odin was working fine on my old laptop running Win7 32bit. Long story short, I was having a few issues with my new laptop, reinstalled Win7 64bit, now Odin is working fine, have flashed the phone a few times using the new computer.
After flashing which kernel you started facing this problem?
Wipe ur phone,re-flash CM7(flash the nightly 181,it's completely stable),uninstall KIES,uninstall old usb drivers,install these usb drivers http://forum.xda-developers.com/showthread.php?t=961956 ,check that USB storage mode is set as Mass Storage and then connect your phone. Also try enabling/disabling USB debugging

The point at which i could no longer mount the USB was when i selected "mount usb" from CWM. I later installed a new kernal which downgraded my CWM, removing the install from external SD option.
So I cant flash a re-flash a rom unless i can it onto the phone which without the USB working is near impossible.

You can directly download the ROM on your internal sd using dolphin browser or opera mobile
I can't do that either as the phone is currently boot looping.

Make sure the cable is properly connected. Check for dust that might prevent it going in properly. Try a different cable. What OS are you using? I found where bootloader is dmg or incomplete Windows fails to detect it. Linux on the other hand detects it. Can't use it but you can detect it.
Can you connect to SW Update Mode? Battery out and plug into PC while holding vol up button.
If nothing works try taking it into the shop.

You can root your phone from there. If you have SW Update. I recommend taking it into the shop if you are still under warranty, If you don't have warranty then you can go ahead and root. Just install a patched bin and fls with Smart Flash Tool. It's one of the stickies (How to unbrick, I think)
hi
new to Android nation
I have the same issue when connecting to USB...
And I managed to flash with custom firmware (latest ZEUS version) and I rooted but the issue with USB connection is still there...
Anyway, I wiil try connecting it to Linux to check if that would work with USB connecting
UPDATE:
OK after some digging, I managed to (at least temporally) solve the issue... After fresh installing official 2.3.4 firmware I booted to recovery and from there formatted the system folder and then installed Zeus v7 firmware... anyway, USB connection and charging indicator work fine at first booting to system... As soon as I reboot the OS USB connection (and charging) get unstable, and after third reboot it completely goes away and the device does not recognize anything: if I connect USB cable it does not show any sing (charging indicator does not show battery charging, nor the device offers me to connect in mass storage, windows recognizes only modem but not the USB storage) and when I connect charger, battery indicator does not flash as charging... Battery monitor tool shows that "battery is discharging" even though the battery capacity seems to increase (according to growing percentage of battery capacity)... Is there a some kind of USB server... I am a total noob to Androiid OS (used to be Symibian from its beggining )so I hope you won`t mind if I used wrong terms in my explanation/comment...
I hope my explanation is not confusing
Cheers
UPDATE 2:
After installing Zeus v7.01 update, battery charging recognition got fixed using both USB cable and wall charger...
Anyway, USB recognition by PC problem still exists... But when in recovery mode I can successfully mount SD card to PC in Mass storage mode...
Will keep you updated... :victory:
I have the d415 and I have been running the latest version of the UberSlimOS ROM, for two months without any major problems. The only problem I do have is that I am unable to connect the phone to the computer. When I plug it in, nothing shows up on the computer or the phone (I have tried this under both Windows 10 and Ubuntu 14.03 & 15.10). I have installed and uninstalled the LG drivers on Windows. I have tried installing another rom (OrionLP) with a clean wipe. Neither of these work. The phone shows up when I plug it in when it is booted in recovery mode, but in regular phone mode I get nothing.
What should I do
