No USB with qemu+macOS+USB+iPads nor any USB-Stick

[Peter]

Hi from Germany.

I want to use macOS to maintain some iPads for my school. I have not
found a way to address them via USB in the VM. Even a simple stick does
not appear.

I've tried some solutions, which I found via google, but no luck.

some examples:

-usb -device usb-kbd -device usb-tablet
-device usb-ehci,id=ehci
-device usb-kbd,bus=ehci.0
-device usb-mouse,bus=ehci.0
-device nec-usb-xhci,id=xhci
-global nec-usb-xhci.msi=off
-device usb-host,vendorid=0x8086,productid=0x0808


My hardware:
Linux debwin 5.10.0-20-amd64 #1 SMP Debian 5.10.158-2 (2022-12-13)
x86_64 GNU/Linux

I also tried:
grub cmdline:
vfio-pci.ids=8086:8cb1,1458:5007,8086:8cad,1458:5006,8086:8ca6,1458:5006
