Seems like every year or two I have to go through making this work again.
Step 1: Load the visor module with the correct vendor and product ID:
root@foo:/# modprobe visor product=0×060 vendor=0×0830
Step 2: Test that the pilot syncs from the command line using pilot-xfer:
root@foo:/# pilot-xfer -p /dev/ttyUSB1 -l
Step 3: Manually configure Kpilot with the username and port /dev/ttyUSB1 (the wizard is broken).
