I have synced the Sony Clié SJ 30 with libusb until pilot-link 0.12.1. Since 0.12.2 it does not work any more. The system is waiting forever instead of establishing a connection to the PDA.
I have to use the old visor module. Then it works again.
I assume this is because of the better support for palm TX. This is really better since 0.12.2. The TX was difficult to use in 0.12.1.
