USB Serial Port problem

Hi All!

I'm having some trouble figuring out the use of the USB serial port. I installed the USB Port Drivers from here, and installed the latest version of TerraTerm (v4.65) from here. I am using the mini USB connector (the one on the mbed, used for programming) to both power the mbed and connect it to the PC. On connecting to the PC, I get the pop up of the folder view (as is normal), but no serial port is detected. I've checked the device manager and TerraTerm. I am using the following example program from the handbook:

#include "mbed.h"              

Serial pc(USBTX, USBRX); // tx, rx

int main() {
    pc.printf("Hello World!\n");
}
Nothing else is connected to the mbed, and I'm using Windows 7 professional.

Anyone have any idea what I might be doing wrong?

 

Regards,

Devesh

All right, I figured out the problem, I needed to close all the explorer windows while reinstalling the driver, and it detected the serial port. I seemed to have overlooked the line in the driver installation instructions.

Sorry folks!
