I'm not yet certain if i wrote hid_profile_create_additional_protocol_descriptor_list correctly, it looks like it's the same list as the protocol descriptor list, except one level deeper nesting and I think this is supposed to have reference to the interrupt PSM. At the moment i'm presuming it's the control channel + 2 -- but I seem to remember seeing an example dump that shows "Protocol specific parameter #2" with the interrupt channel. I'll check it out tomorrow. https://github.com/waitman/sdpd/blob/master/hid.c ./sdpcontrol -l search HID Record Handle: 0x00000002 Service Class ID List: Human Interface Device (0x1124) Protocol Descriptor List: L2CAP (0x0100) Protocol specific parameter #1: u/int/uuid16 17 HIDP (0x0011) Bluetooth Profile Descriptor List: Human Interface Device (0x1124) ver. 1.0 system -> # uname -a FreeBSD afia.waitman.net 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r279971M: Mon Mar 16 14:03:44 PDT 2015 waitman@afia.waitman.net:/usr/obj/usr/src/sys/AFIA amd64 The bt device appears to work properly, except I have no /dev/ubt0 and get errors if I try to start the 'bluetooth' service. ubt0: <vendor 0x0a12 CSR8510 A10, class 224/1, rev 2.00/88.91, addr 4> on usbus0 WARNING: attempt to domain_add(netgraph) after domainfinalize() # service bluetooth start ubt0 /etc/rc.d/bluetooth: ERROR: Unable to setup Bluetooth stack for device ubt0 I changed sdpcontrol a bit for a little more debugging help https://github.com/waitman/sdpcontrol The changes are not that great but /slightly/ more messages in syslog.
