Samsung Tab 2 7.0 (GT-P3100) unable to recognise using Samsung Kies

[mobunvar]

I downloaded Samsung Kies from Samsung website...but it was unable to recognise my tab (GT-P3100). Computer can install its drivers and can detect it. Even ODIN can detect it but not Kies.

I want to update my frmware from ICS to jellybean, i already downloaded the firmware but unable to update it.

I used ODIN but when i poweroff and entern download mode, ODIN was not recognising it.

Any body can help me for that
