It's a simple HID device, and supposed to send volume up / down events. The generic HID driver can already handle it, so you've seen already the result. The problem is that, this HID device behavior is pretty buggy. It sends the same volume up/down events always twice. This made pipewire reacting too much. (Also I'm afraid that there can be a bug in pipewire for handling this, too.) The second problem of this HID device is that inconsistent volume up/down events. When you turn up the volume largely (rotate many) and turn down again. The device sends volume up events multiple times while turning up -- that's normal. But at next, when you turn down, it sends again the volume up event, not the volume down. This repeats until you reach to the neutral point (as it seems). After that point, the device starts sending the volume down. I can fix the doubled key event; the similar workaround is seen for the Platonorics HID device driver, too. But, the latter crazy volume up/down behavior is hard to fix... Maybe Windows driver switch to a different vendor-specific mode somehow, but I can't trace it, unfortunately. You can uninstall the KMP to restore the original driver. I'll check the driver behavior again on my machine. -- You are receiving this mail because: You are on the CC list for the bug.
