[Q] USB connection related problems

hello,i have several problems that are making me very angry.i use updated windows 7 32 bit.
1.i have samsung kies and my device was working normaly,but then today when i connected my phone to pc i got code 43 error device not recognized.i tryed reinstalling kies uninstalling drivers re installing nothing helps i cant even connect when i am in download mode same error.I NEED SOME ANSWERS ASAP COZ IT IS DRIVING ME CRAZY.
2.this one is bit smaller but also annoying,it was happening while usb connection was still working,when i connect my phone(any mode kies or mass storage),then when i copy files from pc to phone it working fine,but when i try to copy something from phone to pc i get random disconnects (connection loss) there is no logical explenation coz its totally random,lets say i copy 100 pics i get dc after 10 then i reconnect phone and click retry he copy 15 more and dc again.
Any1 will any solution plz help coz my phone is at mess atm and cant flash anything.

the source of the usb issue may be your computer.
1) did you always use the same usb port for your phone?
2) how old is your computer?
3) do you live in a humid environment?
I live on guam, and on my older laptop (only two years old!!!), running winxp, 3 of 4 usb ports are no longer usable due to corrosion. they give errors and even when working, sometimes I could lose the connection by moving the cable slightly. also, the last usb port is now getting difficult to use because it's hard to plug in anything
so, if you answered yes to #1, try another port and be prepared to install the drivers again.
if you answered yes to #3, be prepared to replace your usb if they are indeed corroded

well thnx for answer,but my pc is new like 7 months old,usb ports are working just switched mouse and phone mouse working phone not.its driver relater before i had that error and some1 from xda told me to delete everything(kies drivers) related to phone and his drivers and it worked i also see that error(code 43 is common) but fix with uninstalling driver(worked before now doesnt).thing is that something at that moment didnt work well on phone(last time it was my external sd card had to format it)and now pc keeps repeating same error.simply even tho all drivers are installed i get device not recognized,and under device manager it unknown device,also when i tick option to see hidden devices i see omap 3630 but state is unconnected.

When transferring files to and from pc, do you use the original USB cable that came with the phone? Because when i use other cables, i have this issue, when i use the original cable, no probs at all.
if that also doesnt work, try formatting internal and external SD cards

i use original cable and also i did format both external and internal cards several times my first problem is kinda more important atm.

ok i tried connecting my phone to secondary pc running xp gave me same error but simple uninstall of driver and reinstall made it work cant fix it on win 7.
Edit: damn phone wont connect when in download mode cant flash anything -.-.

Connect the phone and go to device manager
If you see the i9003 driver uninstall it then connect the phone to pc again
now windows 7 will download the driver automatically
that's how I fixed my problem

Hi, the Star gT-i9300 and the Tinji I9300 are the same. So you can take a look in this thread.
It seems that you have a driver problem. The message came up directly after connecting the phone ? Or ist the status bar increasing to 100% for one time befor this error appears ?
Installing the correct drivers in the correct way seems to be the main barrier, i wasn't able to get the flashtool run on 2 win7 pc's. XP worked fine from the beginning.
In the thread i mentioned above are also some driver hints, maybe that helps.

so i run flashtool, load MT6577_Android_scatter_emmc.txt, change boot.img with yours one (root-boot.img, i take it in that thread), hit download (now appears an alert and i say "yes") and connect the device (from power off). Now i listen windows usb plug-in sound and flashtool starts to download (with a red bar)...when its at 100% i listen the windows usb plug-out sound and appears that errors...

The first part is like it should be, also the stop after the first 100% ist correct. You should find a message like 'connect USB cable' or something like that in the status bar of the flash-tool.
But after 2-3 seconds it must continue automaticly. Is windows showing a message 'new hardware found' after the first 100% are finished ?
If you connect the phone the first time windows should install a driver at this time.

You took the battery out for a second before you start to flash ? You have tested it with all available USB ports ?
If you hear the 'USB sound' but nothing happens maybe your USB port ist to 'weak' (just a guess). Maybe try it with a external powered USB-hub.
Also installing a different driver is worth a try.

No, sorry. I don't know which drivers i had used. You can try to install PDAnet. This is an often found hint. PDAnet installs drivers automaticly.
Somebody also posted that he had success with this driver.
You disconnected USB cable and battery before starting to flash ?
Update : I started playing around with the flashtool on my Win7 PC where i also wasn't able to flsah anything. Reinstalled the driver and got the same error as you (first 100% ok, then stuck).
I changed the USB cable, used the original delivered with the phone. And all of a sudden it worked !
So maybe try another cable too.

I just downloaded the file and followed instructions, but only option 1 and 2 available
Device type:
1) Normal
2) Special (for example: Sony Tablet S, Medion Lifetab)
Thanks in advance.

Hi, i have the same phone as you but im on ICS instead of JB. anyone has a JB rom ?

PLEASE I AM ASKING FOR HELP ANY DEV/MEMBER WILLING TO guide or making a flashable zip...

I used odin to flash 2.3.6 firmware in download mode and it installed successfully, i wanted my mobile to connect to external storage device(i.e. pen drive) so i made a cable myself and also attache charger power source to that cable(hoping it would work.e. mount & read pendrive) ..After that my mobile wouldn't cnnect to my comp or laptop via usb data cable....it would charge but a usb data connection was not possible .. And finally after trying various methods i think it now is a hardware malfunction(becoz of me) and it should be given to a service center..
Rest all is working fine i can flash diff roms , camera ,wifi all working now using pacman rom so i thought service center would charge me more if i gave my mobile as it is.. they could easily charge more for seeing other rom installed So i wanted stock rom flashable by CWM..
So anyone's help is appreciated.. thanks...

what I understand from your posts is that your phone is perfectly fine but there is a problem with your pc and data cable.
Check with some other data cable,and re-install the samsung drivers for "device not recognized" error.
Use other usb port to check whether its a problem in your pc.

i never saw any such option on any rom yet!
whenever you connect with usb to a PC you get USB connected notification..click on it and enable mass storage.
never saw MTP & PTP in usb connections.
Which rom are you using?
If its 4.+ then try this

In Device Manager in Universal Serial Bus Controllers i uninstalled everything from ASMedia XHCi controllers to USB Root hub... all of them, then clicked scan for hardware changes then i connected my device to computer, then clicked the app USB mass storage for ics and JB ....on computer the elements(USb Root hub, etc.) reinstalled and there it detected my device as unknown device,,,,then for 5-10 sec a message flashed
something like this ,,...". I.I.I.I.I.I.I.I.I Ata mass storage " then it stopped showing not installed...
Using Pacman rom ..does have mtp,ptp,mass storage options..( when i tick any one of the three options it force closes)...
I googled over net on connectivity issue and will need sum time to format c drive and then try again...:fingers-crossed:

I wonder once in odin multi downloader i ticked the debug option only then i clicked delete driver option which may have caused the problem.......

Finally problem solved...replacing charging IC ( as the repairman said) solved comp connection problem then flashed stock rom....

In fact, you don't say nothing about this download zipfile.
We understand that something about usb drivers, but for which device (s).
Can you tell us more...
And we cannot use your download link which is useless

your usb drivers are not installed or are corupt
solution :
press start >search
enter device manager
(phone should be connected)
you should get under port/unkown device
unkown device or mass storage device or something similar
press the one you want unknown device.
choose driver in the new window(its at the top next to general) and choose update drivers
now you get two options use the internet or search in the computer(use the internet)
after that the device manager will install the drivers and reboot the computer and you should be good to go.
if via computer choose browse and navigate to the kies folder usually under samsung in programs and files folder inside search for drivers and tick search sub folders.
that should do the trick else a better bet would be
uninstall kies and sasmung usb drivers connect to the internet then conect device.

what exactly u want
