Wifi OK, bluetooth not identified.

[gcontini]

Kernel version: 4.4.0-21-generic #37-Ubuntu SMP Wifi is working fine. Here is the relevant lspci line: 03:00.0 Network controller: MEDIATEK Corp. MT7630e 802.11bgn Wireless Network Adapter

Bluetooth is not recognized. Attached the output of my lsusb. lsusb.txt I guess "Bus 001 Device 005: ID 0489:e080 Foxconn / Hon Hai" is the bluetooth adapter. No /dev/hci0 device.

Asus model F555L

Hello,

Didi you try this: https://github.com/neurobin/MT7630E/issues/6#issuecomment-196090923 ?

[gcontini]

Today i patched the kernel following the comment you mentioned, but still no result.

I also tried to patch mt76xx.c (note, i don't know what i'm doing, i just copied it from the lines above) around line 1086 i added the following:

/* Foxconn / Hon Hai */ .... { USB_DEVICE_AND_INTERFACE_INFO(0x0489, 0xe080, 0xe0, 0x01, 0x01) }, { USB_DEVICE_AND_INTERFACE_INFO(0x0489, 0xe080, 0xff, 0xff, 0xff) },

to match my usb id. After compiling and inserting the module the lsusb command didn't report the device FoxConn HonHai anymore, and a new entry appeared: Bus 001 Device 007: ID 0e8d:763f MediaTek Inc.

Below the related lines from dmesg:

But still no bluetooth ...

@gcontini There's no need to patch the mt76xx.c, foxconn is already added. Just patch the btusb.c.

Here's a detailed explanation on how to patch the btusb.c

[gcontini]

@Neurobin: I reinstalled a clean version of the kernel and i follow your guide. It didn't work. Here is my lsusb output.

Bus 001 Device 005: ID 0489:e080 Foxconn / Hon Hai 
Bus 001 Device 004: ID 0bda:57b5 Realtek Semiconductor Corp. 
Bus 001 Device 003: ID 046d:c019 Logitech, Inc. Optical Tilt Wheel Mouse
Bus 001 Device 002: ID 8087:8001 Intel Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

@gcontini btusb.ko.zip How about you use my build of btusb. It's for 4.4.0-24 (Ubuntu)

And also reinstall the driver just to be safe.

[gcontini]

Hi NeuroBin, i tried your module but it did not work.

I copied it in folder: /lib/modules/4.4.0-24-generic/kernel/drivers/bluetooth/ (chmod and chown as other modules) rebooted. The module was not loaded.

  # modprobe btusb
  modprobe: ERROR: could not insert 'btusb': Exec format error

  #dmesg 
  [.....] btusb: disagrees about version of symbol module_layout

  # uname -a
  Linux pc-contini 4.4.0-24-generic #43-Ubuntu SMP Wed Jun 8 19:27:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

any advice? thanks for your effort anyway... if you have other tries or suggestions please tell me.

I also opened a bug in launchpad for this. Feel free to vote it.

@gcontini

I have recently installed Xubuntu 14.04.4 LTS and tried to apply the patch. It didn't work (at first), but after about 3 days (a few shutdown and restart) it started working. This is a peculiar behavior indeed, but I am just happy that it somehow worked. :D.

But with 16.04 it didn't take any time to enable. I can tell you to try one more thing:

1. Try adding:

{ USB_DEVICE_AND_INTERFACE_INFO(0x0489, 0xe080, 0xe0, 0x01, 0x01) },
{ USB_DEVICE_AND_INTERFACE_INFO(0x0489, 0xe080, 0xff, 0xff, 0xff) },

like you did before

2. Apply the patch to the kernel (use 4.4.0-24)
3. Do a clean install of the driver and make sure it doesn't show any error like could not insert module blah blah blah
4. Do several shutdowns and restarts (or wait for 3 days :laughing: )

[tobiasBora]

Do you know if adding the two lines you show here would break bluetooth when the lines aren't usefull ? If no shouldn't it be added in the main repo ?

[neurobin]

@tobiasBora : I will add it, or you can add it too with your next pull request.. :+1:

[tobiasBora]

Oh you can do it if you want (except if you don't have the time todo it). For my pull request version 2 I will work on it at the end of the day when I have more free time.

I have good news. I applied the btusb patch using a clean kernel source (4.4.0-28-generic ), i added the two lines above to mt76xx.c and i have the bluetooth working now. I don't know what went wrong before. It should be useful to have them in the standard release.

[neurobin]

@gcontini good to hear :smiley: And yes, the two lines are added in new version
