[PATCH 3/3] Bluetooth: btusb: Enable MSFT extension for Intel ThunderPeak devices

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Miao-chen Chou <mcchou@xxxxxxxxxxxx>

The Intel ThundePeak BT controllers support the Microsoft vendor
extension and they are using 0xFC1E for VsMsftOpCode.

< HCI Command: Vendor (0x3f|0x001e) plen 1
        00
> HCI Event: Command Complete (0x0e) plen 15
      Vendor (0x3f|0x001e) ncmd 1
        Status: Success (0x00)
        00 3f 00 00 00 00 00 00 00 01 50
