I have a command line utility I wrote that has been working great up until Sequoia that reads the macro keys from a Logitech G600 gaming mouse and turns it in to custom commands. it was using the following code, checking if usage was 0x80:
IOHIDManagerRegisterInputValueCallback(
g600HIDManager,
{ _, returnResult, callbackSender, valueRef in
let elem = IOHIDValueGetElement(valueRef)
let usage = IOHIDElementGetUsage(elem)
let pressed = IOHIDValueGetIntegerValue(valueRef)
Now i'm having issues with opening the HID manager:
IOHIDManagerOpen(g600HIDManager, IOOptionBits.zero)
After changing the system security from permissive to restrictive, It's giving the error code 0xE00002E2, or no permission. I can't easily add the sandbox entitlements as this is just a simple CLI application, not a bundled app, and even after setting back to csrutil disable, i'm still getting this error.
So now i'm trying to turn it in to a bundled app and use CoreHID instead. Unfortunately I'm not getting any notifications that aren't the mouse itself. From the above code that was working before, i was looking for usage values of 0x80. I'm guessing that directly corresponds to the usage 0x80 in the HID descriptor. I am receiving notifications via
await deviceClient!.monitorNotifications(reportIDsToMonitor: [] , elementsToMonitor: [] )
which should pick up everything for the device. I know the usage i'm looking for is referenced in the device client because it's in the deviceClient.elements collection.
So is there something in CoreHID that specifically blocks Vendor specified Usage pages from being picked up by notifications?
I've also tried just requesting the elements using
let elemToMon = await deviceClient?.elements.filter({ ele in
return ele.usage.page == 0xFF80 && ele.usage.usage == 0x80
})
let request = HIDDeviceClient.RequestElementUpdate(elements: elemToMon!)
let results = await deviceClient!.updateElements([request])
but that call errors (still trying to figure out exactly how it errors).
Any help would be appreciated, either in figuring out why i'm not getting the HID reports in question using CoreHID, or even what has changed that is causing me to not be able to use IOKit.hid anymore.
Thanks in advance!
