start a terminal or adb shell thing then do
su
cd dev
chmod 777 ttyHSUSB0
or ttyHSUSB1 or ttyMSM2 or whatever port you want.
this worked for me at least!

I connect the physical device and run my application its gives the error
"Error: You do not have read/write permission to the serial port."
I know this is due to permisssion in my device .

device? any idea please let me know.....................
