Thanks for the reply, Roger. I am sending only AT and ATZ commands. So, just resetting and AT commands were not working. But now somehow i made them working. They return OK and i am happy so far.
But now i have another problem. The requests that i send are not exactly being followed by the response. Sometimes, responses come later and my program has moved on to some other "submit" command. So i am unable to relate which response belongs to which command request? My method to submit and read data. 1. Create irp from inpipe. 2. set data buffer of 64 bytes long. (exactly as i my bulk endpoint says the maxpktsize to be). 3. I ran a seprate thread to submit irp to input pipe. inPipe.syncSubmit(irp); 4. Then i submit data to outpipe for my usb endpoint. outPipe.syncSubmit(outIrp); 5. Then i get data buffer from my inpipe. Is that OK? I can post code if you want. I am totally lost in the maize. I have checked with -DJAVAX_USB_MSG_LEVEL=DEBUG3 also but i couldn't figure out much there.
