See if this works, copy this to your /home directory https://www.dropbox.com/sh/5wjhy3cuo...BhD3OIuUa?dl=0
Then

Code:

sudo modprobe -r btusb && sudo mv /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko.bak

Code:

cd ~/polo

Code:

sudo cp btusb.ko  /lib/modules/$(uname -r)/kernel/drivers/bluetooth/

Code:

sudo modprobe btusb

See if it works.
I am hoping it will work this way without the patchram loader, if it doesn't I can change the module and hopefully the firmware can be found

Hi Jeremy,

I'll unzip the package before copying into the home folder right?

Code:

mv: cannot stat ‘/lib/modules/3.13.0-44-generic/kernel/drivers/bluetooth/btusb.ko’: No such file or directory

Thank you

It is zipped? If it is extract to home. I wonder why you got the error

Code:

ls /lib/modules/$(uname -r)/kernel/drivers/bluetooth/

You might have already ran the command once

Yeah I think I had successfully ran the first command once but encountered this-

Code:

sudo cp btusb.ko  /lib/modules/$(uname-r)/kernel/drivers/bluetooth/
uname-r: command not found
cp: cannot create regular file ‘/lib/modules//kernel/drivers/bluetooth/’: No such file or directory

ls /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
