Those keyboards do not return the current device state. Polling will timeout unless there are key presses. This is not a problem during operation but the inital device state query during probing will fail. Skip this step in usb_kbd_probe_dev() to make these devices useable. Not all Apple keyboards behave like this. A keyboard with USB vendor/product ID 05ac:0221 is reported to work with the current code. Unfortunately some Keychron keyboards "re-use" Apple's vendor ID and show the same behavior (Keychron C2, 05ac:024f for example).

Uh, fun.
