Lenovo P51 and Intel Bluetooth 8265

[Yuri Pankov]

Hi,

I'm seeing the following problem on Lenovo P51 laptop with "Intel 
Bluetooth 8265" (as identified by Linux):

ubt0: ubt_ctrl_write_callback:782: control transfer failed: USB_ERR_TIMEOUT
ng_hci_process_command_timeout: ubt0hci - unable to complete HCI command 
OGF=0x3, OCF=0x3. Timeout

The device in question:

ugen0.7: <vendor 0x8087 product 0x0a2b> at usbus0, cfg=0 md=HOST 
spd=FULL (12Mbps) pwr=ON (100mA)

   bLength = 0x0012
   bDescriptorType = 0x0001
   bcdUSB = 0x0200
   bDeviceClass = 0x00e0  <Wireless controller>
   bDeviceSubClass = 0x0001
   bDeviceProtocol = 0x0001
   bMaxPacketSize0 = 0x0040
   idVendor = 0x8087
   idProduct = 0x0a2b
   bcdDevice = 0x0010
   iManufacturer = 0x0000  <no string>
   iProduct = 0x0000  <no string>
   iSerialNumber = 0x0000  <no string>
   bNumConfigurations = 0x0001

I noticed that if I boot into Windows, and then back in FreeBSD 
*without* shutting down the laptop, errors seem to be gone (I haven't 
tested that it actually work, and now the Windows partition is gone, sigh).

What am I missing here, firmware or something else?
