Hi, I am using the Keil sample code to implement the vitual COM communication on LPC2368.
The Communication works well when the hyperterminal is connected to the device.
When the device keeps transmitting ( device runs Ok) without connecting to hyperterminal, but after a while the device hangs waiting for ( while(CDC_DepInEmpty == 0);) to become true.
I am new to USB communication, Please guide me.
