I found a KB article that explains this:

Compatibility considerations for Arm guest operating systems in Fusion VMs on Apple silicon (90364)

https://kb.vmware.com/s/article/90364

......

1. Generic requirements and limitations for all Arm Guest Operating Systems

Other virtual devices:

• EHCI and UHCI are not fully supported at this time

2. Windows

• Other functionalities enabled by VMware Tools are not available at this time, including:
• Drivers: PVSCSI, VMCI, VSOCK, VMMEMCTL, VMMOUSE

.......

I tried to disable the devices by editing the .vmx file setting vmci0.present and ehci.present to "FALSE", but that did not have any effect on the Device Manager list.

I don't know what VMCI is supposed to do, but EHCI is for USB 2.0. Since XHCI also supports USB 2.0, EHCI is not necessary.
