If I build this and active the driver extension, can this be used with Karabiner-Elements (and offload the existing kext) or would that require updating Karabiner-Elements updates to point at this new driver as well?

Thank you!
Jake

Hi friend, i want add a function about "pressure" in VirtualHIDPointing, and i added USAGE (Tip Pressure) in
reportDescriptor_[]

    0x05, 0x0d,                         //     USAGE_PAGE (Digitizers)      
    0x09, 0x30,                         //     USAGE (Tip Pressure)         
    0x26, 0xff, 0x03,                   //     LOGICAL_MAXIMUM (1023)        
    0x81, 0x02,                         //     INPUT (Data,Var,Abs)  

And i modified pqrs::karabiner::driverkit::virtual_hid_device::hid_report::pointing_input

  buttons buttons;
  uint8_t x;
  uint8_t y;
  uint8_t vertical_wheel;
  uint8_t horizontal_wheel;
  uint16_t tip_pressur;

But this cannot work.

I found a "Report" about "Windows pen device" at Sample Report Descriptors, But I don't know how to use it.

Did installation steps. After sudo ./build/Release/virtual-hid-device-service-client which produced:

connected
driver_loaded 1
driver_version_matched 1
virtual_hid_keyboard_ready 1
virtual_hid_pointing_ready 1

but never completed so I stopped it. Now when I run Karabiner-Elements the log shows an unending report of
[Info] [grabber] virtual-hid-device-service-client_ connect_failed: No such file or directory

I've installed this before and gotten it working but with the latest update on Big Sur 11.0 20A5395g K-E stopped working and I've been trying to get it working again. Frankly, I don't really understand all the Mac actions and configurations so finding my missteps would be very helpful.
Thanks

On Big Sur 11.2.3.

Steps to reproduce:

1. Follow instructions in README to uninstall existing.

2. Follow instructions in README to install 1.22.0.pkg, basically like this:

git clone https://github.com/pqrs-org/Karabiner-DriverKit-VirtualHIDDevice.git
cd Karabiner-DriverKit-VirtualHIDDevice
open dist/Karabiner-DriverKit-VirtualHIDDevice-1.22.0.pkg
/Applications/.Karabiner-VirtualHIDDevice-Manager.app/Contents/MacOS/Karabiner-VirtualHIDDevice-Manager activate

3. Follow instructions in Usage section to test, basically like this:

cd examples/virtual-hid-device-service-client
make
make run

Expected results: Test works
Actual results:

$ make run
sudo ./build/Release/virtual-hid-device-service-client
Password:
Press control+c to quit.

Hey! :-)

Which usage page to use for Fn and Brightness up/down ? AppleVendor Keyboard Page or AppleVendor Page Top case? When to use one over the other?

According to its readme, Karabiner-VirtualHIDDevice can be built without a code signature from apple. Will you ever publish a version of Karabiner-DriverKit-VirtualHIDDevice that can be built without a signature?

If Step 3 in the Readme is followed "(Optional) Replace org.pqrs with your domain." you also need to modify ExtensionManager/ContentView.swift to have the correct driverIdentifier loaded.

File: https://github.com/pqrs-org/Karabiner-DriverKit-VirtualHIDDevice/blob/main/include/pqrs/karabiner/driverkit/virtual_hid_device_service/constants.hpp

#include <filesystem> solved this. I didn't open a PR because I am not sure if that's the correct thing to do.

This is not an urget issue like the one above, but, I am getting deprected warnings about kIOMasterPortDefault. To solve this, I guess one could do:

#ifdef __MAC_12_0
  #define __kIOMainPortDefault kIOMainPortDefault
#else
  #define __kIOMainPortDefault kIOMasterPortDefault
#endif

If you are fine with above changes (feel free to correct me), I can open a PR.

Would it be possible to implement a WebAuthN USB HID authenticator using this driver?

https://github.com/acidanthera/VoodooInput/tree/master/VoodooInput/VoodooInputSimulator

I've been having difficulties with K-E since one of the recent releases of Big Sur beta versions. My modifications in karabiner.json are being modified somehow in real time. When I go through the sequence of uninstalling the virtualHIDDevice driver and then installing the beta update (version 13.1.0) my modifications for the Microsoft Sculpt Comfort Mouse work for maybe 10-15 minutes and then a new device is somehow added (a copy of the MS mouse definition) which has the manufacturer set as Apple and the grabber (or something) stops responding to my actual physical mouse defined as a MS mouse. I cannot tell how that phantom mouse declaration is added or if it is responsible for the subsequent loss of perception of my actual mouse but I'd like to know how (and why) this modification takes place outside my own definitions. Thanks for any suggestions.

From the Apple docs and why I ask:

Hello Tekezo,

I am a user of the Kmonad project which is dependent on this project at its
core. I have encountered a problem that I do believe pertains/relates to this project
so I want to ask here for advice or help. I put the reference to my kmonad issue below
but the gist of the problem is described in the following sentence:

My problem

After having used kmonad for weeks, on a macbook pro with
macOS 10.15.7, all of a sudden my keyboard froze and after rebooting my
computer I am presented with an error telling me:

IOServiceGetMatchingService error
^Creset_virtual_hid_keyboard error: (ipc/send) invalid destination port

Is there something obvious that I could have done wrong in order to cause this
problem or does there exist somekind of tool for problem shooting this??

I would like to use my Xbox-360 wireless controller on my MacBook, however the wireless reciever doesn't work with MacOS, but it does work on Linux using xboxdrv. Since this driver runs in userspace on top of libusb, it should be quite easy for me to port it to MacOS, as long as there is a way to forward the events to the system. Hence the need for a virtual joystick device.

For a "clean"† macOS, the Usage section on the README, step 4., will fail on make with the following error:

$ make
/usr/bin/python3 ../../scripts/update-version.py
xcodegen generate
make: xcodegen: No such file or directory
make: *** [all] Error 1

This can be fixed by running

brew install xcodegen

before the make. This should be added to the README.

† For purposes of reproducing this issue, one can run brew uninstall xcodegen to get a "clean" state.

Hi,
I compiled your v0.11.0 code and run the ext manager app. However, when clicking activate button, the ouput said “the operation couldn’t be completed. OSSystemExtensionErrorDomain error 9”
Not sure what’s wrong. Maybe because I dont have driverkit entitlement.
Just asking if you have any insight.

Thank you very much for making this driver available!
I am using it for the MacOS port of my project keymapper. So far it works very well.

Have you thought about adding a homebrew cask for this project, which could be made a shared dependency of Karabiner-Elements and other applications? I think this would prevent many issues with incompatible installations.

Thanks!

control-clicking on the pkg and selecting open gives this error:
The operation couldn't be completed.
(com.apple.installer.pagecontroller error -1.)

Is it possible to create more than one virutal keyboard? In other words, Is it possible to create unique virtual keyboard, each corresponding to a captured (physical) keyboard?

I have encountered a problem when using a single virutal keyboard for more than one keyboard.

To reproduce:

1. Press a modifier key, e.g. shift, on a keyboard (keyboardA).
2. Press a key, e.g. f, on another keyboard (keyboardB).
3. This will produce F.
4. However, now, subsequent presses on keyboardB will produce non-shifted letter (e.g. f), rather than shifted letter (e.g. F).
5. But on keyboardA, the first keypress after #2 will produce a non-shifted letter, and subsequent keypresses on that keyboard will produce shifted letters.

tl;dr -- holding a modifier key on 1 keyboard, and pressing a key on another keyboard creates problem.

Details:

1. Dext version: 1.15.0
2. Uses report.keys.insert for all keys.
   • Does that create problems when used for modifier keys?
   • Anyway, I will try to use report.modifiers.insert instead to see if it solves the problem.
3. Tried using a single socket, and unique socket per device.
   • Doesn't solve the problem.
4. Code: https://github.com/kmonad/kmonad/blob/master/c_src/mac/dext.cpp

Hello, I installed the latest version of the driver 3.1.0 and activated it like mentioned in the README. The driver seem to be loaded and activated but I don't see the virtual keyboard. How should I trouble shoot this?

Thank you,

Edit: Tried version 2.1.0 (with clean uninstall) and still have the same problem.

I am trying to run two instances of the dext at the same time. My first idea was to install different versions side-by-side, but even different versions install files to the same locations and probably collide in other ways that I cannot see. Would it be possible for me to change elements of installation so that two instances can coexist on the same machine and run concurrently?

Very very nice project showing how to build project with DriverKit extension. Far better than USBApp!

One quick question, can you confirm that you must have the appropriate entitlements from Apple before you can successfully load the driver extension?

I have built the app, signed with my cert, and get "Invalid code signature or missing entitlements".

I do have the driverkit.transport.usb entitlement, but not the driverkit.family.hid and driverkit.transport.hid entitlements.

Thanks!

I have constant crashes in the driver.
