Hello, Freebsd-usb.

I've tried to add "attach" rule to devd.conf, but here is one problem: $device-name is "ugen1.2" for example, and "devfs" change owner and permissions on /dev/ugen1.2, but it is only "symbolic link" and real device is "/dev/usb/1.2.0" in such case -- as result, owner and permissions on real device stay unchanged and "blazer_usb" can not access it again :( --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
