Hey, I'currently working on a Driver (and its App) for iPadOS (USB Device). I think have the right entitlements, as my driver gets installed with the app properly (after accepting it in the settings). It also gets loaded once the device is plugged in and so on. However the Kernel is not using the updated Version after I install a new Version of App and Driver to the iPad (at least most of the times). I'm verifying this by reading out the Logs via Console and the Driver prints its Build number on Start(). Sometimes it works like it should but I found no pattern. As far as I understand the iPad should automatically install the new Version of the Driver with the new App if its Build is different from the current one. I'm incrementing the Build of App and Driver automatically post-build so each build the iPad gets has its own Build number (This also works). Steps to reproduce: Cleaning Xcode Build Folder Unplugging the USB Device from the iPad. Building and Installing a new Version of the Driver and the App via Xcode (making sure the build number has changed) Plugging the USB back into the iPad Reading Console output of the iPad However it works (each time if I: Uninstall the app from the iPad manually or via Devices in Xcode Build and install the App via Xcode Open the Settings App and activate the Driver But uninstalling the App each time is taking a lot of time and manual Steps so I would like to fix this issue. Do you have any Ideas? Thanks, Bjarne

I have two different USB devices with different vendor IDs I would like to connect to. I submitted two separate requests for the com.apple.developer.driverkit.transport.usb entitlement for each vendor ID. However I am noticing the provisioning profile only has one of the vendor IDs. How do I submit a request for the USB Transport entitlement to support more than one vendor ID? I'm new to writing a DriverKit driver, so is this even possible?

We have a DriverKit entitlement for our USB driver. We now wish to use this same driver with a variant of our existing application. Of course this application has its own separate App ID and will be published in the App Store alongside our existing application. Will we need to go back to the well and ask Apple for another entitlement?

Hi, I am trying to develop MacOS application which will be connecting to USB devices and should be available in AppStore. So it must be Sandbox and probably I've to use permission com.apple.security.device.usb. I've following requirements: I need to detect USB devices with file system I need to have ability to upload & download files from this device I need to read device serial number I wonder if I can use IOKit for this and it will be compliant with AppStore rules or not?

Hello team, I am using USBDriverKit and Driverkit framework in my application for communication of USB device. After updating my iPad OS to 18 public beta, I am unable to get option to enable drivers in my setting page of my application. However, I am able to see that options in developer beta version of iPad OS 18. Can anyone guide me, how should I proceed further as I am unable to use my USB devices.

I facing issue where the system extension i try to install have message: no related kext found for sysex 'com.apple.usbsoundriver' com.apple.usbsoundriver:extension failed to validate! uninstalling... uninstalling invalid extension com.apple.usbsoundriver Is internet access is required for system extension validation? I install the driver without internet access. This work in some others machine, only fresh reformated Mac machine without internet connection have this issue. Why is this so?

Hi everyone, Are there any new updates on communicating with iPhones via USB-C without needing an MFi chip, especially with the iPhone 15 or upcoming iPhone 16? I'm developing a custom accessory and wondering if the switch to USB-C has introduced any new possibilities for data communication without going through the MFi program. Thanks!

I want to install a driver package without internet access and the installation fail. This I think it is due to it need internet to check for signature with Apple Server. The workaround is to disable System Integrity Protection, but I do not have the administrator password to disable it. How to install a driver and allow a driver to run without internet access and administrator account? This driver is develop by ourself but how to by pass the code signing and security check for others to use this driver on their Mac PC? Currently I am following https://developer.apple.com/documentation/systemextensions/ossystemextensionrequest/activationrequest(forextensionwithidentifier:queue:) to activate the system extension If the extension is inactive, the system may need to prompt the user for approval. Which others API can I use which do not need prompt user for approval? Beside in order to validate the code signing, it need to communicate with Apple server which required internet access. Any method to by pass this validation?

Hello, I'm developing a custom AU plugin that needs to connect to a DriverKit driver. Using the DriverKit sample (https://github.com/DanBurkhardt/DriverKitUserClientSample.git), I was able to get a standalone app to connect to the driver successfully. However, the AU plugin, running in a sandboxed host, isn't establishing the connection. I’ve already added the app sandbox entitlement, but it hasn’t helped. Any advice on what might be missing? TIA!

I have an intra-oral video device that's supported by Apple's AVCaptureDevice. I can use the AV classes to connect to the device and get video. However, this device has a button that's used to acquire still images from the video stream. I can't use the IOUSBDeviceInterface to do an asynchronous read, because the Apple driver has the device opened exclusively. How do I go about receiving the button event in this scenario? I know which pipe to read, based on a bus analyzer when I run this on Windows, I just need to know how to access that pipe when the device is opened by another process.

In iPadOS 17.7 my driver shows up in settings just fine. After recompiling with Xcode 16 and installing my app (containing my driver) on iPadOS 18, the app shows up in settings but the driver-enable button is missing from Settings. When I plug-in my custom USB device, the app cannot detect it and I am left with no way to manually enable the driver, as I did in the previous version of iPadOS.

Can anyone definitively say if USBDriverKit is supported on the new OS and 3.2 USB iPhone device? This would be a fantastic way to work with novel devices such as custom cameras. Thanks.

Development environment: Xcode Version 15.1 (15C65), macOS 14.2.1 (23C71) Run-time configuration: macOS 14.2.1 (23C71) DESCRIPTION OF PROBLEM 1.The device supports sleep and wake functionality, and sleep/wake can be achieved on both Linux and Windows. 2.Does macOS's USBSerialDriverKit support sleep and wake? If so, how can I implement it? 3.Is it necessary to modify system permissions on macOS to use a USB serial device for sleep and wake functionality? STEPS TO REPRODUCE I don't know how macOS performs power management for serial devices. The sleep wake function fails to pass the test on macOS

Hi We are developing a iPad accessory that connects to the USB-C port of an iPad Pro. For debugging, we are using iPad pro M4 and iPad Pro 12.9 (fifth gen). We are aware we can debug the app over wifi, but this process is slow and cumbersome. Is there a USB-C hub ( I guess that supports thunderbolt ) that would allow us to connect the iPad to both our Mac and to the iPad accessory simultaneously ? Thanks

Is there a way to detect at run-time whether the device supports USBDriverKit?

Currently system extension need to be activate through an .app, and then need to manual allow in System Settings, Privacy and Security Pane with root user password How to install driver extension/system extension without any manual user click and just to install and allow all the permission using script?

我的app想要在USB设备（移动硬盘，typec）的插入和拔出的时候收到通知，并且实现手动弹出移动设备的功能。 上述功能在ios上可以实现吗？如果可以的话，是否方便可以给我一些资料我看一下吗？

I'm try to use CoreHID to communicate with a usb hid device that sends custom reports. I have been able to create a client, but when I try to access the elements I get this: IOServiceOpen failed: 0xe00002e2 This looks like a low level error. I'm hoping someone in the community has seen it, maybe using IOKit and can point me to some information.

I have a USBDriverKit driver which tries to send vendor-specific DeviceRequests to the IOUSBHostDevice. A few short months ago this worked, and as far as I know, the only change since it last worked is an update to macOS 14.5. The dext user client calls through to the driver, which wants to do this: ivars->mDevice->Open() ivars->mDevice->DeviceRequest() ivars->mDevice->Close() the problem is that the call to Open returns 0xe00002cde, which is kIOReturnNotOpen. If I don't call Open, but simply call DeviceRequest, I get the same result, kIOReturnNotOpen, which I would expect. I'm pretty sure that in macOS 14.4, the call to Open() did not return an error. I haven't seen any system logs that clue me in to why Open() is failing. It would be handy if the error gave me some reason why the device cannot be opened. Has anyone else seen this? I've searched high and low and I can't find any examples of dexts which actually do anything at all with a USB device.

How do I adjust the latency timer for the AppleUSBFTDI driver? I am developing an app in Swift using Xcode on a MacBook Pro M1 running Big Sur, for clinical brain-computer interface (BCI) research. The app needs very low-latency streaming from an external USB device. The external device is a headset which connects via Bluetooth to an FT231X chip mounted on a USB-Serial dongle. The FT231X chip reads timestamped EEG data from the headset. The issue is that the AppleUSBFTDI driver is buffering the packets coming in from the headset, which causes jitter in the timestamps. Typically, with proprietary drivers from FTDI, the solution is to reconfigure them to reduce the latency timer to 1ms. The Info.plist is edited to add new key/value pairs. Is there a similar solution for Apple's built-in driver?
