Public bug reported:
Binary package hint: udev
I have written a custom udev rule which will assign group "users" to any
/dev/tty* devices (USB serial converters). I need this for Palm Pilot
syncing over USB cradle.
According to the README:
If the ordering of files in this directory are not important to you,
it's recommended that you simply name your files "descriptive-name.rules"
such that they are processed AFTER all numbered rules in both this
directory and /lib/udev/rules.d and thus override anything set there.
I have placed the rule in /etc/udev/rules.d/ttyusb.rules
Sometimes udev seems to "forget" this rule on boot, when plugging in the
device /dev/ttyUSB0 is group "root". Doing "touch
/etc/udev/rules.d/ttyusb.rules" an re-plugging restores group "users".
As I said, this is only sometimes and not reproducible. For the moment,
I placed the "touch..." command in /etc/rc.local, which seems to help.
What can I do to debug this further?
