Hi,
I am working on USB virtual port . I am Using MCB2300 board with LPC2378 . I want to generate two virtual comports using USB .
It is working fine with the single virtual port ( code given by Keil and .inf file for windows ).
Now I want to acheive two comports . I have downloaded code for lpc2148 from nxp site and i try to port it to lpc2378 . When i connect USB cable to PC , it is showing two virtual ports but the ports are not getting opened when i try to open them with the hyperterminal .
Please help me if anybody worked successfully on acheving 2 virtual ports using the USB.
Regards, Kranthi .
You need to give more detail!
What, exactly, happens when you try to open them with hyperterminal? Do you get any error messages from hypoterminal?
Can they be opened by any other application?
Does Device Manager give any clues?
