Unplugging and reconnecting the keyboard restores input. Keeping ObinsKit running prevents the problem. A read-only userspace reader that keeps USB HID interface 1 open also prevents it, as does usbhid.quirks=0x04d9:0xa292:0x00000400 without either application running. Commit ca28aff0e1dc ("HID: quirks: Always poll Obins Anne Pro 2 keyboard") added HID_QUIRK_ALWAYS_POLL for product ID a293. The variant identifying as 04d9:a292 exhibits the same symptom. Apply the quirk to this product ID as well.
