:>Description:
:     SierraWireless MC7455 LTE modem is not supported by umsm(4).
:>How-To-Repeat:
:     Install the MC7455 LTE modem and try ppp or cu against it.
:
:>Fix:
:Patch prepared agains an OpenBSD 6.0 current as of 2016-08-16.
:Only USB devices IDs needed to be added.
:
:The third serial port (/dev/cuaU2) answered to AT commands and worked for ppp 
connection.
:
:This mPCIe card has USB 2.0 and USB 3.0 but on my RCC-DFF 2220 the USB 3.0 
pins on the card conflicted with PCIe pins ont the board. Pins 23 to 33 were 
taped out on the card to make this work.
