Re: Activating Bluetooth on intel AX200,AX201,AX210 modules

Hi Björn

   #1  running   Current -15   updated  on  12:th  of  july  from github 
sources, on  this laptop.

    #2   yes,  I   have an 0x0026 entry in 
/usr/src/sys/netgraph/bluetooth/drivers/ubt/ng_ubt_intel.c:

     #3   If  I   issue  iwmbtf   install  command    4 times 
consecutively    the  "service bluetooth start ubt0 "     command 
appears  to  work  ,

            hccontrol  commands   appear  to  run,

            btsockstat    runs


       # usbconfig show_ifdrv      says:

               ugen0.6: <AX201 Bluetooth Intel Corp.> at usbus0, cfg=0 
md=HOST spd=FULL (12Mbps) pwr=ON (100mA)
*   ugen0.6.0: ubt0: <vendor 0x8087 product 0x0026, class 224/1, rev 
2.01/0.02, addr 5>*

*        device is  available*

     SO  is  the conclusion  that   the  AX201 BT module needs   to  be  
wacked   on  the head  4  times    to   bother waking  up  ?

        shouldnt  device initialization  at system  startup  take care  
of  that, ´?

     I  dont     have a bluetooth mouse with me  presently  but will  
try one  next week .
