Support for RTL8723BU on kernel 2.6

[francescoagostini93]

Hello, i'm trying to port rtk_btusb driver on kernel 2.6.35.3 compiled for i.MX51.
The dongle producted by LM tecnologies is an LM811 with RTL8732BU, as suggested by vendor, for the bluetooth driver i'm try to compile troy branch. Inside troy branch there is 3 different driver, btusb on the root and rtk_btus. For the 2.6.35.3 kernel i can compile only the rtk_btusb inside the bluetooth_usb_driver folder. When i probe driver got follow log

rtk_btusb: Realtek Bluetooth USB driver ver 2.11
rtk_btusb: btusb_probe intf->cur_altsetting->desc.bInterfaceNumber=0
rtk_btusb: btusb_probe can_wakeup=1 flag2=0
rtk_btusb: patch_add
rtk_btusb: pid = 0xb720
usbcore: registered new interface driver rtk_btusb

and when i rise hci0 interface got

rtk_btusb: btusb_open start pm_usage_cnt(0x1)
rtk_btusb: btusb_open hdev->promisc ==0
rtk_btusb: download_patch start
rtk_btusb: check_fw_version : read_ver_rsp->lmp_subver = 0x8723

rtk_btusb: Rtk patch end 0
rtk_btusb: btusb_open end pm_usage_cnt(0x0)
root@2win ~$ rtk_btusb: hci0 evt 3
rtk_btusb: btusb_notify : hci0 evt 3

if i try to run hcitool scan, i can't see any device. And if i try to run RFComm server i can't see it from other devices. If i try to do same operation with BT only dongle with btusb standard driver it works fine, but i need combo module wifi-bt. Reading other issue i tried to load wifi driver before and rise wlan0 interface. No result
