libratbag: Trying to add support for Logitech Performance MX but ratbagd --verbose=raw hangs permanently

Following the wiki over at https://github.com/libratbag/libratbag/wiki/Adding-a-new-device I added a logitech-performance-mx.device file to /usr/share/libratbag/devices/ after running lsusb. Which resulted in the following:

Bus 002 Device 002: ID 8087:8000 Intel Corp. 
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:8008 Intel Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 10c4:8a2a Cygnal Integrated Products, Inc. HubZ Smart Home Controller
**Bus 003 Device 017: ID 046d:c52b Logitech, Inc. Unifying Receiver**
Bus 003 Device 014: ID cb10:1133  
Bus 003 Device 013: ID feed:2260  
Bus 003 Device 012: ID 1908:2220 GEMBIRD 
Bus 003 Device 011: ID 1a40:0101 Terminus Technology Inc. Hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

So the logitech unifying receiver is at 046d:c52b. My .device file looks like this:

# Logitech Performance MX - unifying
[Device]
Name=Performance MX
DeviceMatch=usb:046d:c52b
Driver=hidpp20

But the part about running sudo /usr/bin/ratbagd.disabled --verbose=raw never outputs anything. No error, no empty result, nothing. It just continues to run infinitely with a blinking cursor.
