look inside the phones settings to enable the connection options

Is your device low on battery? Try charging it for a few hours first. And remember that Nokia's can't charge through USB.

Hi respeced member I am new to this forum. For the couple of days any computer can't detect my nokia mobile 5300 when it connect through USB supported data cable. I checked it's data cable through other device and found it alright. Normally whenever this mobile is connected through data cable it pops up connection mode like Nokia mode, print mode,....etc. But at present it's connection mode is blurred or disable. Please help me to find out the solution.
