[Q] USB Replacement problem - Galaxy S II Q&A, Help & Troubleshooting

Hi,
My phone was acting really strange, batterydrain, weird software actions, nothing seems to help.
I got the advice to open it, because I didnt had any ganranty left, so I did, it was full of sand from the beach en I could see on the paper marks that I had some waterdamage.
After a few nights of searching I decided to order a new USB connector true Ebay.
So now I replaced it, all is working fine, but still got the batterydrain.
But the biggest problem for now is, that I cant connect with my PC..... Before the replacement this was no problem at all!!
I tried evertything what came up in my mind, New drivers, New KIES, USB debugging, USB Storage....
Do you guys have a solution or some ideas wat I can try?!
Thanks in advanced!

try:
- the back usb ports behind your pc
- a different sync (usb) cable
if you have otg an adapter cable test a disk on key to make sure data+\-\sense pins are intact
if the disk on key does not show up works it means
- the micro usb connector is faulty
- software problem
on my front usb ports, i sometimes get mtp "stuck" in xp so i switch to the back ports and it works fine

System settings is 4.0.3 ICS Stock Samsung, no root, nothing changed in phone, everyting is as it is when you buy it.
Windows error is that my laptop doesn't recognize the USB device.
Thanks for your reply

Thanks for your reply, I have tried all of the USB ports on my laptop and on the PC of a friend, no result.
If I plug it in, my SGS2 will charge, so I guess that the +/- point are ok?
I dont know what a otg an adapter cable is to test a disk or someting.... Sorry I am a noob on this front, can you explain this a little bit more?

"vcc" is the positive voltage or "+"
"GND" is ground or "-"
sense is responsible for cable\connection identification by using different resistors bridged between GND and Sense (charger,mhl,otg,audio dock) like so:
Sense-----wire----resistor-----wire----GND
(otg is without resistor)
"data +" & "data -" are for passing digital serial information (usb data)

a usb OTG adapter is a cable that makes the phone act like a usb port on your computer, and you can use a "usb flash drive" \ "usb stick" \ "usb memory"
so if you can get a otg adapter you can tell if the DATA+ and DATA- pins in your phone usb socket are broken

I don't want to offend you mate but are you sure that USB Debugging mode is on?
Under Settings > Applications > Development you should see an option for USB Debugging -- if that isn't checked you won't be able to mount your phone.
Do you see some errors in Device manager?
If yes, try to update driver marked as error.
You're using the cable that comes with the phone right?
And go to device manager
expend Universal Serial Bus controllers see if you have SAMSUNG mobile USB composite device if not, right click on one of the "USB composite device"* and click update device drivers.
Hope we can come up with solution for you mate.

No offend taken, but yes I am sure. Thanks for thinking with us!
The error in Device manager is "Unknown USB Device" what you suggest I already tried, but no result.
I have the new drivers, I use the original USB cable, but I switch my USB Connector, witch I order thrue Ebay in China, so maybe there is something different with the connection points in the USB connector.....
That is something I may have to find out with the OTG Cable.

i hope it will work out for you, i'm assuming the 1 or 2 of the pins in the middle of the connector are broken, lets just hope i'm wrong
