ok, but by using the tilp-devel mailing list, Tijl Coosemans (FreeBSD porte=
r) whould have got your mail. That's OK, I CC'ized it...

This change when you attempt an operation (such as Ready) with success. It =
has nothing to do with (un)plugging the cable.

Argh, some important functions seem to be unimplemented on BSD...
There are 2 ways: use a libusb which implement this call (but they seem to =
be BSD specific) or port the SilverLink kernel module to the BSD platform..=
.

Unfortunately, there is an issue with USB management under BSD
