My USB wireless keyboard is detected, but not working

Hello,
A friend of mine bought a new keyboard and gave me his old one (a Ziyou Lang K68 60% mechanical keyboard) and when I tried plugging it in, it recognized the keyboard but it did not receive any input. I have tried the keyboard on other devices (Windows 10) and it doesn't work. Before taking the keyboard, I tested it on my friend's computer and it worked perfectly fine.

Here's the output I get from "lsusb":

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0bda:b85d Realtek Semiconductor Corp. Bluetooth Radio

Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

The keyboard is "SHARKOON Technologies GmbH 2.4G RF Keyboard & Mouse".

Here are the last lines of  "sudo dmesg":

Re: My USB wireless keyboard is detected, but not working

Please use [code][/code] tags. Edit your post in this regard.

I have tried the keyboard on other devices (Windows 10) and it doesn't work.

So… it's fried?

Well, let's see: Google says it's a bluetooth keyboard?
So *at best* the sharkoon thing is a dongle, not the keyboard?
Google also says

Fn+Q switches to 2.4G wireless mode, Fn+W/E switches to Bluetooth mode

does that help to connect the keyboard?

Also, for a huge d'ohh moment: batteries?
