I just got a Zonet USB adapter and got it working with Hotsync and also BlueFiles FTP, but I am having trouble with Dial-up. I get it to connect with the Treo in dial-up mode and ask for username, password and phone number. I enter all that info in and then it says it is dialing and then I get a pairing error and my laptop and Treo suddenly are not paired anymore. I re-pair and then the same thing happens. Any ideas? I am using the Widcomm drivers that came with the USB adapter.
