RFC: Add HID bus type in hid_device_info

[DJm00n]

It happens that Bluetooth HID gamepads are having the same VID/PID as when connected via USB (DualShock4 and DualSense for example). But they have different report descriptors and thus input/output reports. We need a way to differentiate them.

To address this I have added a new hid_bus_type enum and hid_bus_type bus_type field to hid_device_info struct:

typedef enum {
	/* Unknown bus type */
	HID_API_BUS_UNKNOWN = 0x00,

	/* USB bus
	   Specifications:
	   https://usb.org/hid */
	HID_API_BUS_USB = 0x01,

	/* Bluetooth or Bluetooth LE bus
	   Specifications:
	   https://www.bluetooth.com/specifications/specs/human-interface-device-profile-1-1-1/
	   https://www.bluetooth.com/specifications/specs/hid-service-1-0/
	   https://www.bluetooth.com/specifications/specs/hid-over-gatt-profile-1-0/ */
	HID_API_BUS_BLUETOOTH = 0x02,

	/* I2C bus
	   Specifications:
	   https://docs.microsoft.com/previous-versions/windows/hardware/design/dn642101(v=vs.85) */
	HID_API_BUS_I2C = 0x03,

	/* SPI bus
	   Specifications:
	   https://www.microsoft.com/download/details.aspx?id=103325 */
	HID_API_BUS_SPI = 0x04,
} hid_bus_type;

Implemented it for Windows, libusb, hidraw and MacOS backends.

I didn't test Linux version yet.

[DJm00n]

@mcuee @Youw can you test it on Linux?

[Youw]

Technically I could, but right now I'm a little short on time regarding everything, so I can only ask not to make any expectations when I'll do it I can only promice that I will, and I'm also going to see if this can be implemented for macOS as well

Here is the test results on my Raspberry Pi 400 running 64bit Ubuntu Linux.

@DJm00n You can see that libusb backend output is expected. As for the hidraw backend, on one hand it seems to work, but on the other hand, many reports bus type "0". Is this expected by your design? Take note hidraw backend has the feature of ""split by usage_page/usage" as per https://github.com/libusb/hidapi/issues/287 .

unable to open device

@DJm00n For the I2C HID device, you have the following codes for Windows.

	/* I2C HID devices have a special ACPI ID
	   https://docs.microsoft.com/windows-hardware/drivers/hid/plug-and-play-support-and-power-management */
	if (wcsstr(device_id, L"ACPI\\PNP0C50") != 0) {
		dev->bus_type = HID_BUS_I2C;
		goto close;
	}

And I checked the Microsoft I2CHID device in Device Manager "Human Interface Devices" section and indeed it has a "Compatible device id" and "Matching device id" value of "ACPI\PNP0C50".

[mcuee]

@DJm00n And for those "\?\hid#converteddevice", I am not exactly sure if 255 is the right one to use. I tend to think they are more like "virtual hid bus type". But I am okay as well if you use 255 if there are no better ways.

[mcuee]

@DJm00n From what I see, the following Windows codes are not good enough (just using "Device_InstanceId"). On the other hand, for the purpose of HIDAPI, maybe it is still okay. I do not think we can do much with the "Microsoft I2CHID device" anyway.

	/* Get the device id from parent devnode */
	len = 0;
	cr = CM_Get_DevNode_PropertyW(dev_node, &DEVPKEY_Device_InstanceId, &property_type, NULL, &len, 0);
	if (cr == CR_BUFFER_SMALL && property_type == DEVPROP_TYPE_STRING) {
		free(device_id);
		device_id = (wchar_t*)calloc(len, sizeof(BYTE));
		cr = CM_Get_DevNode_PropertyW(dev_node, &DEVPKEY_Device_InstanceId, &property_type, (PBYTE)device_id, &len, 0);
	}

[DJm00n]

@mcuee Thank you for testing it!

I don't have such I2C or SPI HID devices in person. So I need some further help.

Can you debug the code a bit and look what exact device_id (acquired with DEVPKEY_Device_InstanceId property) your devices are having?

For example you can add:

wprintf(L"DEVPKEY_Device_InstanceId: %s\n", device_id);

before if (wcsstr(...)) checks.

[mcuee]

@DJm00n This is what I get.

@DJm00n The Microsoft I2C HID device has the following

DEVPKEY_Device_InstanceId: ACPI\DELL091A\4&27F2A591&0.

If I look at the Device Manager "Human Device Interface" entries, Device_InstanceId printed out is the same as what is listed as "Device Instance Path" in Device Manager.

The one you want to get here is "Compatible IDs" which has two values, "ACPI\PNP0C50" and "PNP0C50".

[mcuee]

@DJm00n From the link in your code, https://docs.microsoft.com/en-us/windows-hardware/drivers/hid/plug-and-play-support-and-power-management

The ACPI 5.0 Specification includes support for HID Class Devices. the ACPI definitions for HID I²C are as follows.

Field	Value	ACPI object	Format	Comments
Compatible ID	PNP0C50	_CID	String in the format of ACPI0C50 or PNP0C50	CompatibleID

[mcuee]

Same for SPI HID device. https://docs.microsoft.com/en-us/windows-hardware/drivers/hid/plug-and-play-for-spi

The ACPI 5.0 Specification includes support for HID Class Devices. the ACPI definitions for HID SPI are as follows.

Field	Value	ACPI object	Format	Comments
Hardware ID	Vendor Specific	_HID	String in the format of VVVVdddd (e.g. MSFT0011)	VendorID + DeviceID
Compatible ID	PNP0C51	_CID	String in the format of ACPIxxxx or PNPxxxx	CompatibleID

[mcuee]

Compatible ID should work for your purpose, no matter it is USB, Bluetooth, I2C or SPI. https://docs.microsoft.com/en-us/windows-hardware/drivers/install/compatible-ids

@mcuee

As for the hidraw backend, on one hand it seems to work, but on the other hand, many reports bus type "0". Is this expected by your design?

I have fixed it. Please check when you have a time.

[mcuee]

@DJm00n Yes the latest git is okay for Linux (tested with my Raspberry Pi 400 running Ubuntu 64bit Linux).

@Youw could you please review the code?

[mcuee]

@DJm00n You may want to disable the following warnings.

Maybe this one can be considered for next release 0.12? Or maybe 0.13?

[DJm00n]

Hey @Youw!

I have added MacOS implementation (KUDOS @JoergAtGithub) and updated this PR. Need someone who can test MacOS implementation.

[Youw]

Sample on my mac machine:

hidapi test/example tool. Compiled with hidapi version 0.12.0, runtime version 0.12.0.
Compile-time version matches runtime version of hidapi.
