Hello, all.
After checkeing this Thread, I could success to install Widdcom software on my VAIO SRX7S/PB (Japanese Version).
As
www.jonscaife.com/bt explained, I needed to remove microsoft driver editing on the registry.
Now I can manage activesync on the Bluetooth with iPaq2210 which I could not do BluespaceNE software.
Thank you very much sharing your experience.
P.S. my device shows VID_044E&PID_3002, I needed to modify btwusb.inf
Thank you again
