### macOS

libusb and pkg-config can be installed via Homebrew.

If imx_usb fails to claim interface, com.apple.driver.usb.IOUSBHostHIDDevice
needs to be unloaded so libusb can claim, run:

```
sudo kextunload -b com.apple.driver.usb.IOUSBHostHIDDevice

Hi, do you know how to make this work on High Sierra?
It seems that sudo kextunload -b com.apple.driver.usb.IOUSBHostHIDDevice does not work.

Sorry, took me a while to realize there is a comment here so a bit late response. Anyway, the idea is to stop whatever is claiming your device to let imx_usb_loader has a chance to use it. On my board, it was com.apple.driver.usb.IOUSBHostHIDDevice but if that doesn't work for you, it's likely some other module is claiming and so you have to unload that one instead, check dmesg to see which one.
