Hello, I am trying to get my Texas Instruments DSK6711 DSP board communicating with my Windows 7 64-bit DELL Inspiron 15R laptop. Cara Instal Windows Xp Di Hp Pavilion Dm1 here. The DSP board has a DB25 IEEE-1284 compliant parallel port ad my laptop has a USB port. I bought a USB to DB25 Parallel Port Adaptor cable to connect the DSP board to my laptop. Hp Sales Builder For Windows Configurator.  Windows installs the USB Printer Support driver automatically but the DSP utility fails when invoked to check the connectivity. The DSP board documentation suggests I change the parallel port mode to ECP or EPP but I have no idea how to do that. I am also using Code Composer Studio V2.1 to send exedcutable code to the DSP board which is expecting an LPT printer port to be available but there is only a USB port with the adaptor cable plugged in. Can anyone suggest what I can do to get this cable working with my laptop and DSP board? Hi, “The DSP board documentation suggests I change the parallel port mode to ECP or EPP but I have no idea how to do that.” I suggest that you may contact the adapter's manufacturer to check this issue.
