I've a line like this that creates /dev/pilot link in my local udev rules:
BUS="usb", SYSFS{product}="Palm Handheld*", KERNEL="ttyUSB*[13579]", SYMLINK="pilot"
And it seems to work fine for doing normal sync operation to Gnome Palm applet (well, not sure about that KERNEL parameter, however ttyUSB0 and ttyUSB1 look exactly the same, no other way to specify "use second device" as far as I can see). But, if I use the USB connection to connect to the network (using my Linux box as gateway by running "pppd auth -chap +pap login local ms-dns 10.0.0.1 10.0.0.1:10.0.0.2 pilot" and doing SNAT) I've noticed that sometimes when I disconnect, the ttyUSB* devices are not removed by udev.
When devices are removed, I'm getting something like this in my log files:
kernel: visor ttyUSB0: Handspring Visor / Palm OS converter now disconnected from ttyUSB0 kernel: visor ttyUSB1: Handspring Visor / Palm OS converter now disconnected from ttyUSB1
However, when devices are not removed, I'm getting a bit different message:
kernel: usb 2-1: USB disconnect, address 4 kernel: visor 2-1:1.0: device disconnected
I've just started playing with my Palm under Linux, and so far I've only noticed this when using PPP over USB. So far when doing plain-old synchronzation (to gnome Palm applet) it seems that devices are always created and removed as expected.
Has anybody else noticed this and/or has advice what to do?
Thanks, Alex
