New Kernel Driver Issue [Solved]

I have a USB bluetooth dongle that tells the computer that it is a certain device but it is actually a fake. This fake bluetooth usb dongle requires a modified driver because the actual driver does not work with the fake hardware.  Everytime there is a new kernel, I must place the driver into the /lib/modules/5.6.whatever folder and then when i want to use the device, i have to sudo modprobe btusb.  With the new kernel update, i tried to do the same thing.  It is giving me an error:

modprobe: FATAL: Module btsub not found in directory /lib/modules/5.6.8-arch1-1

Any suggestions on how to fix this?

Read the output (and the command you type) carefully. btsub isn't the driver name.

sudo modprobe btsub
[sudo] password for root:
modprobe: FATAL: Module btsub not found in directory /lib/modules/5.6.8-arch1-1

All i need to know is where to place the file named btusb.  I used to put it in the /lib/modules/ (arch version) folder.  Now it must be placed somewhere else because it isnt working when i put the patch file in that folder.

again, the place is correct you are typing the wrong command, you need to modprobe btusb and not btsub

yes, I understand. 

sudo modprobe btsub
[sudo] password for root:
modprobe: FATAL: Module btsub not found in directory /lib/modules/5.6.8-arch1-1

That makes no sense - at all - is your other module literally called btsub? And not a replacement for the normal module btusb?

Re: New Kernel Driver Issue [Solved]

I think it was a mistake in the command.  I kept hitting arrow up to redo the command that didnt work in the shell.  Then when i went to Super User  #, i had to retype the command and used btusb instead of btsub.  (it worked that time).
