>How-To-Repeat:
Here are the lines in /etc/usbd.conf :
device "Palm Handheld Device"
devname "ucom0"
vendor 0x0830
product 0x0060
attach "/usr/sbin/ppp -background -unit0 palm; /etc/rc.d/named restart"
detach "/bin/sh /root/close-palm.sh"
in /boot/loader.conf :
# palmt3 cradle
uvisor_load="YES"
>Fix:
Don't ever plug T3, however won't be so nice for synchronization.
