I am installing a brainmaster eeg device onto a compaq nx9030 laptop. the brainmaster unit uses a serial connector, and the laptop only has usb. i am using a cables unlimited adapter. The brainmaster device cannot recieve information from the laptop but it can connect to com port 3. the problem is none of the ports show up in device manager. should this matter since i am using usb, i have another computer running the device but it connects through the serial connection. both systems run xp pro without service pack 2. does anyone know if there are any comport related issues with xp. i dont think it matters since it is usb but, the other machine works that uses serial connector.
