[ adding some more CCs ] Okay, so apparently we didn't register with input, but only hiddev / hidraw. appleir 0003:05AC:8240.0005: hiddev0,hidraw4: USB HID v1.11 Device [Apple Computer, Inc. IR Receiver] on usb-0000:00:1d.3-2/input0 Therefore ->input_configured() callback has never been called, and thus we oops due to appleir->input_dev being NULL when the first raw event is reported. Could you please provide report descriptor of the device? The driver apparently relies on it being registered with hid-input, but for some reason that doesn't happen.Here is the relevant lsusb output that I think contains what you're asking for (I had to unbind usbhid for it to include the descriptor): Bus 005 Device 003: ID 05ac:8240 Apple, Inc. Built-in IR Receiver Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 ...Ok, thanks for the report. Could you please test the following patch which should solve your problem (hopefully)?
James, any reults from testing Benjamin's patch, please? -- Jiri Kosina SUSE Labs
