--- Comment #5 from Hans Petter Selasky <hsela...@freebsd.org> ---
First of all:

wPortChange=0x0001 means UPS_C_CONNECT_STATUS (/usr/include/dev/usb/usb.h)

Secondly at XHCI level (xHCI_Specification_for_USB.pdf) PORTSC section:

xhci_roothub_exec: port status=0x000202a0

CCS = 0 and PED = 0, there is no device connect.

That means the hardware itself reports no device present!

Can you try to compile multimedia/webcamd with input device support, and then
try to attach webcamd to the device?

I suspect the device itself is triggering this by changing the pullup/pulldown
values on D+ .
