QEMU USB passthrough -device usb-host: drive exists

I am using Qemu, running on an Arch Host to use a Windows VM, and I need to passthrough the webcam. It is an integrated webcam using USB>=2.
lsusb yields for this deviceBus 001 Device 002: ID 0c45:6723 Microdia
Here is the script I am using (win-start.sh):
#! /bin/bash
sudo qemu-system-x86_64
-m 8G
-enable-kvm -cpu host -smp cores=4
-vga virtio -display sdl,gl=on
-drive file=win,format=raw
-device nec-usb-xhci
-device usb-host,hostbus=1,hostaddr=2
2>&1 win.log
But this stops with:qemu-system-x86_64: -device usb-host,hostbus=1,hostaddr=2: drive with bus=0, unit=0 (index=0) exists
And I cannot find where the error is. The VM boots without a problem when I remove the 2 -device lines.
This script is based on what I could find there :
https://superuser.com/a/1077369/1021190
And the folder is setup as such:
