Public bug reported:
The USB to serial device built into most USB syncing Palm Pilots creates
two USB serial ports. Only the second of these is used for the hotsync
protocol, I think the other is used for PPP connections. In any case,
the /dev/pilot symlink is supposed to point to the second registered
serial port.
However, /lib/udev/rules.d/40-pilot-links.rules makes a /dev/pilot
symlink for *any* ttyUSB device associated with a Palm adaptor. This
means that depending on the order in which udev processes the hotplug
events, either of the two serial ports could end up with the /dev/pilot
link. On my system at least (Core 2 Duo, so 2 CPUs) the events are
apparently *not* reliably processed in the order you'd expect.
Therefore about half the time, after inserting the device, the
/dev/pilot link points to the wrong ttyUSB device.
However, I'm not sure how to encode udev rules to do this correctly.
