modprobe btusb error

Question

I am using a Ubuntu desktop 20.04.4 LTS with linux kernel 5.15.0-41-generic. I bought UB500 from tp-link. After plugging it doesnt turn on-off.

I tried every steps exactly and following the answer from document but it's throwing an error when

~$ modprobe btusb
modprobe: ERROR: could not insert 'btusb': Invalid argument
~$ lsusb

What exactly steps you did? The accepted answer is wrong for your system if you literally ran all those commands. — Pilot6, Jul 18 '22 at 09:49
Please [edit] your question and add output of lsusb command. — Pilot6, Jul 18 '22 at 09:51
And if you want to load a module you need to make it with sudo. — nobody, Jul 18 '22 at 09:53
@nobody The device mentioned has been added to the 5.15 kernel already and doesn't require tinkering with btusb. So it is an XY Problem — Pilot6, Jul 18 '22 at 09:55
@Pilot6 I applied the accepted answer, couldn't turn it on or off before I did. But the system saw the device before. — tbturk, Jul 18 '22 at 12:55

If you have exactly the same device (TP-Link could sell another device with the same name), then you don't need to do anything to get it working.

You can see it here

So you built a wrong kernel module and replaced the correct one. You can't start it because it doesn't match the kernel version.

You can fix it this way:

Boot with a previous kernel using grub.
Reinstall the 5.15.0-41-generic linux image and modules using Synaptic.
Reboot again.

It's UB500, It is written on the back of the device. – tbturk Jul 18 '22 at 12:59
