Have a look at this link:-

Open device manager, by right clicking computer then manage then Device Manager and then under Port See the USB Serial Port number

Now use matlab with that port number to send and receive data.
You are using CDC Class of USB

i had tried that, but i didnt see any changes in the device manager (USB controllers) when i connect and disconnect the microchip board....i had installed microchip software in my pc and when i try to work with the board using c program, it was working........do i need to install any other drivers on my pc??

even in the ports i dont see any USB connection

Do you know programming
means are you expert or have some knowledge of 8 bit pic


what i am guessing is that you have not programmed your controller with the appropriate code thats wjy this happens.
if you are new try basic programming then go to usb

no i am not new...i did programming before....but i dont have a clear idea about the work i am doing now....

Have you done some experiment with USB.
Like USB HID
USB CDC
USB Mass Storage Device

Hello gupta,

you could use AHid.dll to interface Matlab - http://www.embedded24.net
AHid.dll implements an USB HID interface on Host side.
