patch

The C099-F9P eval board has a USB hub and 3 USB devices, the first
device is the USB port of the ZED-F9P GNSS chip, the second is a FTDI
serial bridge connected to the UART of the ZED-F9P and the third is a
FTDI serial bridge connected to the UART of the ODIN-W2 communications
chip.

The first device is recognized by FreeBSD (by umodem), the other two
are not recognized.
