Hi HPS, Both of the below option is not working. My Device is a Linux machine that is having a Gadget Serial driver. Physically device side we have USB-C port while at host side we have USB port. This device is used as COM port to access the serial port. My Device side Linux is getting panic as soon as I attached the USB to FreeBSD. Any view on this? If I stopped the enumeration at FreeBSD using command (sysctl hw.usb.disable_enumeration=1), so device side Linux is stopped crashing. Can you suggest me some area at device side that might be causing the crash.

You can try: usbconfig -d 0.2 set_config 0 --HPShome | help
