Serial Communication Issue

When trying to run my first program on Basic stamp 2, I get error message: "no basic stamps found".

After trying to identify the Basic stamp 2 from the editor the response is: feedback = "yes", echo = "yes".
Cable used is a USB to serial and FIFO buffer has been disabled on the COM port.

Also, when the 9-Volt is unplugged from the Basic stamp 2 the response when identifying the device is the same.

I'm not sure what could be wrong with the connection.

Any ideas is appreciated.

    IS the BS2 plugged in to the board correctly?

    There are hundreds of usb/serial adapters, not all work. Search the forum for your type and see if others have used it successfully.

    FTDI-based adapters work well, among several others.

    Regarding the battery ... The Stamp has to be operating for it to be recognized by the PC. It needs power for this. feedback= and echo= are simple checks on the serial cable connection (or USB to serial adapter). These will work if there's no power to the Stamp.

    I'm using Belkin f5u409 for USB-to-Serial connection.

    I've downloaded the latest Editor software version and drivers from Parallax.

    Issue seems to be with Belkin usb-to-serial cable. I checked other forums and found that it is incompatible.

    I'm able to use the BASIC stamp for now from a direct serial connection on my desktop PC.

    I guess I'll need to get another usb-to-serial cable if I want to use with my laptop...
