How to use deviceRequest of IOUSBHostDevice / IOUSBHostInterface?

QUESTION

How to use deviceRequest of IOUSBHostDevice / IOUSBHostInterface?

Asked 2020-Jan-28 at 14:57

I'm currently experimenting with Apple's I/O Kit to develop a kernel module. I'm trying to create a device driver for a USB Wireless Card (TP-Link WN722N-v1) using IOUSBHostDevice. I managed to get the kext loaded and it probes correctly with the card, but I need to send the firmware to the card, which I am trying to do in probe(). I don't have the perfect knowledge of how everything goes, but it seems that I need to send a request to the configuration endpoint 0, but the ways I have tried I get kernel panic, and the other examples I have are using an obsolete DeviceRequest with no exchangeable arguments with the new deviceRequest. I have a reference for writing the firmware from github project "BrcmPatchRAM" but all the forks use old IOUSBInterface instead of IOUSBHostInterface. I have search this site for similar questions but found none helpful in this matter, I also searched Apple developer website documentation and it references also the old ways of DeviceRequest. Which is the right way of re-writing this for example:

Putting together a few pieces here:

Using some other implementation of this function gives me an error when loading the driver and tells me that I am sending the request before calling prepare, but I did called prepare before sending the request.

This gives us a pretty big clue that your issue is with the memory buffer. So let's see where the creation and prepare() are happening:

Install BrcmPatchRAM

Install one of BrcmPatchRAM.kext or BrcmPatchRAM2.kext or BrcmPatchRAM3.kext depending on macOS version, never both. Also, install one firmware kext BrcmFirmwareData.kext or BrcmFirmwareRepo.kext, depending on installation location, never both. Keep in mind that BrcmPatchRAM3.kext also requires BrcmBluetoothInjector.kext to be installed. Starting with macOS 10.15, this is the only supported configuration because due to framework changes BrcmPatchRAM.kext and BrcmPatchRAM2.kext are incompatible with macOS 10.15. In case you forget to install BrcmBluetoothInjector.kext, Bluetooth will appear to be available but it won’t work at all. Also, if you have a non-PatchRAM device (or you’re not sure), install one of BrcmNonPatchRAM.kext or BrcmNonPatchRAM2.kext, depending on macOS version, never both. Although these kexts do not install any firmware (these devices have firmware built-in), they still depend on BrcmPatchRAM/BrcmPatchRAM2.kext.
BrcmPatchRAM.kext: for 10.10 or earlier.
BrcmPatchRAM2.kext: for 10.11 - 10.14.
BrcmPatchRAM3.kext: for 10.15 or later.
BrcmFirmwareData.kext: Most appropriate for bootloader injection. This is the preferred configuration.
BrcmFirmwareRepo.kext: Install to /System/Library/Extensions (/Library/Extensions on 10.11 and later). This kext is slightly more memory efficient than BrcmFirmwareData.kext, but cannot be injected by a bootloader.
Advanced users: For custom firmware injectors, install the injector plus BrcmFirmwareRepo.kext. This works from either /S/L/E or through bootloader injection. Optionally, you may remove all the firmwares from BrcmFirmwareRepo.kext/Contents/Resources. If you’re using the injector through the bootloader, the IOProviderClass in the Info.plist for BrcmFirmwareRepo.kext must be changed from "disabled_IOResources" to "IOResources".
BrcmNonPatchRAM.kext: for 10.10 or earlier
BrcmNonPatchRAM2.kext: for 10.11 or later.
BrcmPatchRAM.kext, BrcmPatchRAM2.kext and BrcmPatchRAM3.kext can be installed either through bootloader kext injection or placed in /System/Library/Extensions (/Library/Extensions on 10.11 and later). Make sure to install only one of them, depending on system version. BrcmFirmwareRepo.kext does not work with bootloader kext injection, unless using a device specific firmware injector. BrcmFirmwareData.kext can work with bootloader kext injection. You can also use a device specific firmware injector (in conjunction with BrcmFirmwareRepo.kext). In this scenario, BrcmFirmwareRepo.kext does work from bootloader kexts. You will find device specfic injectors in the firmwares directory of the git repository. They are not included in the distribution ZIP.

Support

BrcmPatchRAM supports any Broadcom USB bluetooth device based on the BCM20702 chipset (possibly other chipsets are supported also, but this has not been tested).
