Hi,
I have a Intel Cherryview based laptop with Braswell XHCI. The laptop has two
usb ports, a USB-A port routed to USB3 (this works) and a USB-C port routed a
USB 2 bus.
The USB bus routed to the USB-C port does not appear under FreeBSD.
xhci0: mem 0xa1a0-0xa1a0 at device
20.0 on pci0

Hi,
Thanks for your reply.

Could you tell me if this multiple usb instance interface is something
we are missing or something we implement in a different manner?
We only attach to PCI devices and devices ACPI provides.
Can you dump "pciconf -lv" and maybe also provide an ACPI dump?
