Android Kitkat 4.4.2 showing offline in Adobe Flash Builder 4.6 & 4.7

Hi,

I am facing issue in compiling Adobe AIR application from Adobe Flash Builder 4.6 and 4.7 directly to Android Kitkat 4.4.2 using USB calbe. I am using Samsung Galexy Tab 4 Modal SM-T 231, when I am debugging my application using Samsung Galexy Tab 4 SM-T231 having Android Kitkat 4.4.2, it is showing device offline but my device is on mode and I can transfer file form my pc to Android Tab.

But I can compile and debug my application directly to Samsung Tab 2 Modal No. GT-P3100 from Adobe Flash Builder  4.6& 4,7 both without any issue. Please find below snapshot for your reference.
