USB serial adapter, cu write: Device not configured

Sun Mar 18 19:25:39 UTC 2012

dear Warren,

I did everything you write me but even using devfs.rules or by hand
modify the ownership or write permission, or using the root user,
it doesn't work. These are the rules activated by rc.conf with:

devfs_system_ruleset="usb_devices"

cat /etc/devfs.rules

[usb_devices=10]
add path 'ugen*' mode 0777 user seaman group dialer
add path 'ttyU*' mode 0777 user seaman group dialer
add path 'usb/*' mode 0777 user seaman group dialer
add path 'ums*' mode 0777 user seaman group usb
add path 'cuaU*' mode 0777 user seaman group dialer
add path 'da*s*' mode 0660 group usb

I put 7 just to be sure to try everything.. normally I just
need "rw" permissions.

Thank you
FabioDive
