FreeBSD personal.jesus.com 6.0-BETA2 FreeBSD 6.0-BETA2 #0: Thu Aug 11
19:31:34 IDT 2005 root@:/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:
ubt0: vendor 0x0a12 product 0x0001, rev 1.10/8.28, addr 2
ubt0: vendor 0x0a12 product 0x0001, rev 1.10/8.28, addr 2
ubt0: Interface 0 endpoints: interrupts=0x81, bulk-in=0x82, bulk-out=0x2
ubt0: Interface 1 (alt.config 5) endpoints: isoc-in=0x83,
isoc-out=0x3; wMaxPacketSize=49; nframes=6, buffer size=294

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.
