How to enable USB passthrough for QEMU on Apple Silicon M2?

I’ve been using QEMU on macOS (Apple Silicon – M2) and ran into an issue I hope someone here can help me with.

I'm trying to use USB passthrough to attach external USB devices (like the Alfa AWUS036NHA Wi-Fi adapter) to my QEMU virtual machine.

Even when using flags like:

-device usb-host

-usb -device usb-

host,vendorid=0xXXXX,productid=0xXXXX

or other variations, the VM doesn’t recognize the USB device.

The device is detected correctly on macOS, it shows up under system_profiler SPUSBDataType, but QEMU seems unable to passthrough the device to the VM. Some online threads suggest this might be related to limitations of USB handling on Apple Silicon, or System Integrity Protection (SIP).

so I'd like to ask Is there any working method to get USB passthrough working on Apple Silicon?

Most documentation I found seems to be for x86 hosts, and it’s hard to find reliable info for Apple Silicon specifically. I'd really appreciate any tips or shared experiences!

You may find it easier to use UTM instead which provide a GUI interface around QEMU for M-series Macs.

Here is a page from the QEMU documentation which shows various options (the XHCI option to launch QEMU may be useful):

I know trying to map Apple USB ports to a third party driver/utility is tricky. It has been some years since the last time I did this on macOS (never with QEMU on macOS)....and it has been even longer since I last used QEMU itself (I think I used a GUI interface then myself although I have used QEMU command line options as well).

Edit: If using an M-series laptop, did you allow the USB device to be approved to connect in macOS? You may want to configure the "Allow accessories to connect" Privacy & Security System Setting to "Always when unlocked".

If your Mac asks you to allow an accessory to connect - Apple Support
