Yes, the keyboard should be able to be connected to the PS5 via USB. The PS5 supports USB keyboards; however, whether it works in a specific game depends on the game itself. This model is a wired USB keyboard with a German layout and should therefore be suitable for supported games. The RGB lighting, the number pad, and the mouse included in the set are not critical for basic PS5 compatibility.
The keys for the characters "greater than" and "less than" are normally located on a keyboard between the Shift key and the "Y" key. If these keys are missing on your keyboard, you can also enter the characters using ASCII codes: Press the ALT key and enter 60 for "less than" and 62 for "greater than" on the ten-key pad.
If you are using a keyboard with a special layout, check the key assignment or use the key combinations provided for your specific layout.
You may also need to install an appropriate driver from LogiLink... If this does not work, the keyboard may be defective and you will have to return it under warranty.
