USB not working

(1/3) > >>

Rajesh:
Hi,

On my SGS I am not getting USB mode selct popup when I connect USB to PC. I just get a beep indicating the phone is charging. It used to work earlier , after Camera repair by Samsung Service Center it was intermittetent but worked twice. Now totally unusable except for charging.

1. I tried all settings of USB mode (kies, media, mass storage,ask)
2. Tried  USB debugging ON/OFF.
3. Using Samsung USB cable
4. PC port is fine tested with other USB 2.0/1.1 devices

As a result the phone is shown as unknown device. Hardware enumeration failed. Does it indicate hardware fault in phone USB? Is such problem of USB rectifiable at mobile service shops ? (Samsung service center takes inordinate time to repair)

please help and suggest what I could do before giving it for repairs.

with best wishes,
Rajesh

I had two problems with USB connection

1. USB connection not detected by the phone - I cleaned microUSB connector of phone using alcohol and toothbrush 3-4 times after some gap. This removed the corrosion of microUSB port pins and the phone sharted detecting USB cooncetion as well got detcted properly by Windows Vista as "Samsung Composite device" (and not as unknown device). At this point Galaxy S started getting recgnised and mouted and USB drive in " mass storage mode"

2. Still Kies was not able to make connection to phone in "kies mode". The "connectiing" icon use to keep rotating endlessly". After 3 hours of troubleshooting including reinstall, reinstall drivers, removing files with log file name extensions,  I found that Windows defender (antimalware protection) service was slowing the detection of the phone.  I went to control panel -> classic view-> windows defender and disabled the real time scan and rebooted. This resolved the issue.

Please check if Windows defender or any other realtime antivirus protection is causing the malfunction.

with best wishes,
Rajesh.

Hi Rajesh  :)
I'm facing the same problem as you are. After connecting the phone to the laptop, it starts 'charging' but the 'USB connected' message doesn't appear.  :\
Were you able to find a solution to this problem?

Have you installed the "SAMSUNG_USB_Driver_for_Mobile_Phones_x86.exe",supposed you are on Windows.
