[Q] Unable to connect to PC

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
http://drivers.softpedia.com/get/MOBILES/Samsung/Samsung-Galaxy-S-USB-Driver-for-Windows-x64.shtml

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.

very weird pb.please help

Hy guys,
I was trying the other day to flash a friends Galaxy S stock 2.2 but i couldnt connect the phone to the pc. In the pull down menu, it didnt appeared the dialog to click to go for usb mass storage or anything.
I've selected USb Debugging, clicked in the options for USB Mass Storage, and when i connect the phone to PC and cable, both play the connected sound, but still nothing more. What could be the pb? and how can i solve it?
Pleaaaaase help
And thanks in advance

also to mention. I'm running win 7 on 64bits, drivers installed correctly and my phone has no pb at all when it comes to connect it to the PC.
So....Odin not recognizing, PC not recognizing phone...what to do....?

try different ports or re-install your drivers(kies) take a look on the Themes and Apps section i saw a thread for drivers... try on a different computer....

have tried reinstalling the drivers, also using all the ports available on my pc. still the same pb.:-<

Definately PC issue. Reinstall Kies drivers.

[Q] Phone semi bricked and unknown device in download mode

Hey all,
I've got a problem related to my Micro USB port (at least I think it is).
[Long story]
I've got a very annoying issue right now. Today I flashed Team ICSSGS RC4.1. Later when I connected my Galaxy S to my PC with the usb cable, no recharging icon appeared and my pc did not react to the connection at all.
Thinking it was a bug in RC4.1 (as OneCosmic RC 2.3 had the mass storage issue) I searched the ICSSGS thread, but not a single issue about mass storage mode was posted. So I flashed Devil kernel, hoping to fix it, but it didn't. Reflashed RC4.1, but problem still persisted.
I went radical and recovered a nandroid backup in CWM of ICSSGS RC3.0 (the one is was running earlier today), but somehow the recovery failed and left me with a semi-bricked phone. (Actually the 2nd time in a row when recovery semi-bricked my phone.)
Only download mode works. Recovery and normal boot bootloop.
[/Long story]
In short:
When connecting to PC to flash with Odin:
-At first the PC did not even notice the phone being connected through USB. Nothing happens.
-After blowing in the contacts of the Micro USB port, PC recognizes connection, but gives "Unknown device" error upon connecting. Reinstalling Samsung drivers does not work at all. Tested on laptop and home PC.
-Somehow I always have to blow into the Micro USB port to create contact and to get the PC to recognize a connection. But that's about it. "Unknown device" every time.
-When I plug in wall charger, the big battery icon appears, but stays grey all the time and after half a minute the phone boots, starting the bootloop.
Could it be that my Micro USB port is broken?
Any solution for this?
Thanks in advance!
I feel so stupid for recovering that nandroid backup. Otherwise my phone would still be working...

you will need the nexus drivers for your comp found here : w w w.multiupload.co.uk/BUCFT8M42 as your samsung drivers are no use now.

Thanks for your advice: Going to test it right away.
Unfortunately your link does not work for me.

I had the same problem but replacing the cable solved it.

Sorry for the duff link http://www.multiupload.co.uk/BUCFT8M42N

Tested this morning with someone else's cable, still the same issue.
Tried the Nexus driver, but still nothing. Also having troubles again to let the usb connection register. It connected after cleaning it, but now it does not seem to connect at all.
Could it be that the phone is completely busted and therefor breaks usb connection?
Haven't heard such a story yet, but is it possible?

I've got it sorted out.
Since it might be helpful for others that are searching for a solution:
1. I cleaned out my Micro-USB port using micro interdental brushes and a few drops of isopropyl alcohol. It also doesn't hurt to clean the contacts of your USB cable, just to be sure.
2. Connected the phone to my PC. This time my pc recognized it as a serial gadget.
3. Disconnected the phone and installed Nexus S driver (because of ICS rom on my Galaxy S)
Next connection my device was automatically recognized as an android phone.
Odin saw my phone as well and I could flash again!
My phone is back on Team ICSSGS RC4.2.
Thanks everyone for helping!

Same Issue cant fix
Hey guys im glad to see others are having the same issue but i cant seem to fix mine.
Assume im an idiot and ive missed something out but ill explain my situation....
Galaxy i9000 - windows 7 32bit - put ics on it a few weeks back following a guide on youtube (had never used odin or anything like that before) got it working but now have no usb comm options in the ics settings. now when i plug the usb (when it does detect at all) it says driver havent worked - device manager shows unknown device - i try update the driver and it says the best driver is already installed.
Im completely stuck and want to revert back to gingerbread so i can use my usb functions again. If i can get odin to see my phone again ill be relieved.
Any ideas?
Cheers guys! Seán.

But most of all, check your usb cable and try switching to another USB port after rebooting your PC

USB connection to PC not working

My phone was working perfectly until a few days ago when I noticed that USB connection to PC stopped working. I was running imilkas CM9 v2. USB used to work perfectly and then randomly, it just stopped working, I don't have a clue what caused it because I did not flash anything on the phone.
When I connect my Phone to the Computer via USB cable, my phone start charging and nothing else happens. My computer does not even show that I connected a USB device.
I've tried 3 other computers with the drivers and the same issue (1 comp with xp and the others with win 7). Also, not to mention, I've tried multiple USB cables, including the original. I've tried USB Debugging on and off, doesn't make a difference.
I've tried ADB and it does not recognize the device either.
In CWM when I mount USB storage, it does not work.
In download mode, when I plug in the cable, nothing happens, odin does not detect any connection.
USB connection to the computer is Dead and it does nothing but charge my phone.
Here is a list of things I've already tried to fix the issue:
1. Factory Reset.
2. Used Mobile Odin, reverted to my Phone's Stock GB ROM (KK2). On stock GB, I tried Kies Air and that worked fine, but USB connection had the same issue
3. Formatted the Internal Storage
4. Removed the SIM Card and Micro SD card, still no luck.
5. re-installed CWM (without pc)
6. Installed Paranoid Android 0.2
7. Called Samsung... They said they wont service my phone because I'm located in Canada and I have the International Note. They told me I'd have to take it to the country I bought it from.
If anyone can offer any help that would be great.
Thanks in advance.

As I have mentioned in my post that I've already tried multiple different cables, including the original.

Could be factory defect. flash original rom and take it to service center.

Phone used to work perfectly fine before. Already flashed original rom, it did nothing. And I've already talked to Samsung. They won't help me.
I've already mentioned that in my op! I would be nice to hear suggestions/solutions other than the ones I've mentioned.

Can anyone please help me out with this? I even tried cleaning the usb port a bit more, but no avail. I am guessing the file that recognizes a PC connection got corrupted some how. Anyone know how to update or replace that?

Can't root in any way, out of ideas

Lovely community,
I'm trying to instal a custom recovery (TWRP) for my mi 9t pro.
However, although it does charge and fastcharge, it doesn't get recognized by my computer (or any other computer I've tried).
It only shows "unrecognized usb device".
I figured this would be a driver problem, so I reinstalled drivers, even forced a driver instal through device manager for this device but somehow it still doesn't show. Unfortunately, without a pc connection, rooting my phone gets really hard.
Ofcourse USB debugging, etc. are enabled.
I'm out of hope or ideas, maybe you guys could help me out here? I've been struggling for over 7 hours so far ahha so I figured I should ask for help.
Thanks in advance!!

Obvious things to try at first are changing the USB cable, trying different USB ports on the computer and, if possible, trying a different computer.
A poor quality or damaged USB cable is often the problem with these types of issues. Followed by a dodgy USB port, that's had a lot of use, on an older computer.

Hi Robbo,
Thank you for the reply! I've tried multiple computers, ports, cables and the usb port has been replaced so that shouldn't be the problem either... any other clues?

I assume you are using Windows 10?
Normally, connecting the phone to the PC, with the standard USB cable, Windows will automatically recognise the phone and install the required drivers without you needing to do anything? After this adb and fastboot should recognise the device without any further input.
Try removing the phone from Windows device manager and then plugging it in to the PC and see if it can automaticallyinstall it's drivers successfully.
