OK, so I tried adding all of them to the HID_QUIRK_IGNORE LIST, i.e.
#define USB_DEVICE_ID_APPLE_GEYSER_ANSI 0x0214 #define USB_DEVICE_ID_APPLE_GEYSER_ISO 0x0215 #define USB_DEVICE_ID_APPLE_GEYSER_JIS 0x0216 #define USB_DEVICE_ID_APPLE_GEYSER3_ANSI 0x0217 #define USB_DEVICE_ID_APPLE_GEYSER3_ISO 0x0218 #define USB_DEVICE_ID_APPLE_GEYSER3_JIS 0x0219
{ USB_VENDOR_ID_APPLE, USB_DEVICE_ID_APPLE_GEYSER_ANSI, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_APPLE, USB_DEVICE_ID_APPLE_GEYSER_ISO, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_APPLE, USB_DEVICE_ID_APPLE_GEYSER_JIS, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_APPLE, USB_DEVICE_ID_APPLE_GEYSER3_ANSI, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_APPLE, USB_DEVICE_ID_APPLE_GEYSER3_ISO, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_APPLE, USB_DEVICE_ID_APPLE_GEYSER3_JIS, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_APPLE, 0x020E, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_APPLE, 0x020F, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_APPLE, 0x030A, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_APPLE, 0x030B, HID_QUIRK_IGNORE },
however this did (and cannot) work, as the product id stands for both keyboard AND mouse.
It will however work for the internal infrared receiver (which is also affected).
#define USB_DEVICE_ID_APPLE_IR 0x8240
{ USB_VENDOR_ID_APPLE, USB_DEVICE_ID_APPLE_IR, HID_QUIRK_IGNORE },
Could someone please add this to the quirk list in hid-core.c in git ? Please note that one can even do this from userspace via
libhid-detach-device 05ac:8240 modprobe appleir
Anyways, back to the above problem. Can one somehow tell the hid-core to load the appletouch driver when it detects any of these devices and then initialize on top of that ? The appletouch driver is completely ignored (doesn't even enter the atp_prope function as usb_register registers with device/product tuples that are already taken by hid....
Any ideas ?
