setting USB 2.0 doesn't really work with ARM64 VMs

[d0wntime]

Describe the issue Setting USB support to USB 2.0 in a VM appears to not disable XHCI/USB3, and devices (including the USB2 bus) are still attached to a USB3 bus. This is visible in the QEMU options in the VM that's fired up in ps auxww output or by using the export command button.

The problem here is that you’re using ARM64 which doesn’t have any supported USB 2.0 bus.

[aonez]

It does work using emulation, so it does work.

[d0wntime]

which are you saying works @aonez ? you're missing a couple words.

UTM's UI isn't working if I tell it to give me only USB 2.0, and it gives me XHCI. please just give me an unsupported bus ... USB 2.0 may not have a supported bus, but I do have devices working on an OS that doesn't like QEMU's XHCI implementation, by means of attaching external devices. with this OS, I have to use an external keyboard to get keyboard input to work.
