simple question but did you change the com port in the Pioneer "ufu.exe" program to match the serial port com in the laptops? by default, the program uses com 3, but when the connection is live, com 4 appeared as another radio button choice when I was checking out the connection. since my USB adapter uses com 4, the program must have detected it & provided the other choice.
the other issue is data speed. my USB adapter is 9600 by default but the ufu program wants 19200 base speed & 57600 data send speed.
haven't tried to update yet but before I do, I planned on setting my USB adapter to 57600 or maybe 115200 bps data speed. Maybe yours is also set at 9600, like the old Windows Hyperterminal days.
getting serial devices to communicate sometimes can be tricky. we've all been spoiled by usb.
Also, did you select the "Go On" in the service menu before launching the ufu program?
I sure hope it's something simple. This should work.
