Still it detects as a mouse, with no right click and no scrolling. I understand it's not a support channel and I'm sorry, but on a slight chance it might be a bug I'm posting here. For what it's worth, I see reports of 'unknown main item tag 0x0' prior to this patch and I also see this warning with or without this patch. Here's an example with a Magic Mouse from Feb 2024: https://bugzilla.kernel.org/show_bug.cgi?id=86931#c11 The vendor and device ID match, so the kernel should load the driver but I don't see your system loading it. Those logs would begin with 'magicmouse' instead of 'hidgeneric'. Could be worth exploring with dkms and modprobe - I haven't tried the install script on fedora There is no lines with the word "magic" in the dmesg output. I get that the 0x0 message is some other thing — but thanks for the hint that it should show "magicmouse".

Interesting, I'm not sure why the driver isn't loading for you. Everything looks good compared to my installations. The modprobe entry even shows 'alias hid:b0003g*v000005ACp00000324 hid_magicmouse', which should pick up the driver. What about 'modinfo hid_magicmouse'? Any udev rules or is secure boot enabled? Any warnings about unsigned drivers or a tainted kernel? The 2 entries in hwinfo look fine. I get those same two entries when connected via usb but not bluetooth, which makes sense given the first interface is for 'apple_mfi_fastcharge'. I am curious - is the behavior different when connected via bluetooth? What version of fedora are you using? I can try this on a clean install I'm using a KDE spin of Fedora 40, with packages all updated to latest versions. For some reason I get only one Bluetooth device when I disconnect the trackpad from USB, and that's neither the trackpad, nor my Bluetooth mouse. Maybe hwinfo is broken in that way?.. No relevant warnings in dmesg, and I do have secure boot enabled. Grepping for "tainted", only one line: [ 8.234042] CPU: 7 UID: 0 PID: 216 Comm: kworker/7:4 Not tainted 6.11.6-200.fc40.x86_64 #1 Here's what dmesg appends when I disconnect from USB, turn it off and then on again: $ sudo dmesg | tail [66630.597969] hid-generic 0005:004C:0324.0013: unknown main item tag 0x0 [66630.598379] input: Magic Trackpad Mouse as /devices/virtual/misc/uhid/0005:004C:0324.0013/input/input73 [66630.598840] input: Magic Trackpad as /devices/virtual/misc/uhid/0005:004C:0324.0013/input/input74 [66630.598999] hid-generic 0005:004C:0324.0013: input,hidraw1: BLUETOOTH HID v3.14 Mouse [Magic Trackpad] on 8c:3b:4a:50:ef:d5 $ sudo modinfo hid_magicmouse filename: /lib/modules/6.11.6-200.fc40.x86_64/extra/hid-magicmouse.ko.xz license: GPL file: drivers/hid/hid-magicmouse description: Apple "Magic" Wireless Mouse driver parm: emulate_3button:Emulate a middle button (bool) parm: emulate_scroll_wheel:Emulate a scroll wheel (bool) parm: scroll_speed:Scroll speed, value from 0 (slow) to 63 (fast) parm: scroll_acceleration:Accelerate sequential scroll events (bool) parm: report_undeciphered:Report undeciphered multi-touch state field using a MSC_RAW event (bool) That's the first notable difference I've seen so far.

The path to the driver is different and I'm not sure what to make of that. Admittedly I don't know much about secure boot but I've been testing with it turned off.
Okay something weird happens on Fedora, so I guess I'll take this to Fedora forums. $ modprobe -n --first-time hid_magicmouse && echo "Not loaded" || echo "Loaded" modprobe: ERROR: could not insert 'hid_magicmouse': Module already in kernel Loaded $ sudo modprobe -v hid_magicmouse $ sudo lsmod|grep magi $ sudo lsmod|grep hid uhid 24576 2 hid_multitouch 36864 0 i2c_hid_acpi 12288 0 i2c_hid 45056 1 i2c_hid_acpi Thanks for writing the module, Callahan! I hope it gets into the kernel soon :) |
