its the com tower but im using a usb to serial adapter because my laptop doestn have any serials. the tower is using a brand new 9v battery. how do i check the cable?
the computer port(the usb one) works great with everything else ive used it for, like thumbdrives

Well, we all know how well USB-serial converters worked for the FRC/Edubot controllers.

I think you'll need to get a computer with a serial port to download. The USB and COM towers work differently, specifically the COM tower shuts down and has to be woken up again, where as the USB stays on the entire time it is plugged in. If you configured the LEGO software to work with the USB tower, then that's your problem. (I think)
