FreeBSD personal.jesus.com 6.0-BETA2 FreeBSD 6.0-BETA2 #0: Thu Aug 11
19:31:34 IDT 2005 root_at_:/usr/obj/usr/src/sys/GENERIC i386

The kernel is GENERIC. I initially installed 6.0-BETA1, then
cvsupped/builtworld to get
to 6.0-BETA2.

It's a Motorola USB Dongle. It's label says: MOTOROLA SYN0717A
usbd says:

I assume you mean in sys/netgraph/bluetooth/socket/ng_btsocket_l2cap_raw.c .
It will take me some time. I'll get back to you on that.
