Porting OpenBSD UMB(4) to FreeBSD for MBIM Support


  • We are using a Sierra Wireless EM7455 with PPP, but need to get an MBIM and/or QMI package working for a project we are working on. Does anyone at Netgate have experience porting an OpenBSD driver to FreeBSD? Can I pay someone to do that? :)

    We are not currently accepting paid development work. However we have an internal ticket open for this already, I'll add your voice there. It would be very nice to have that driver.

    umb was ported to NetBSD more recently and the same developer was at one time working on a FreeBSD port but appeared to abandon the effort. He's probably in the best place to port this. I have no idea if he's open to offers.
