Hello.
I'm trying to use Sierra Wireless EM7430 on Panasonic CF-RZ6 with High Sierra 10.13.4.
The card is detected as USB device by default.
And I use Legacy_Sierra_QMI_10.13.kext. Here is my Info.plist.
With Legacy kext, the card is recognized as WWAN card, but Modem Software shows Unknown.
Connect button is disabled in System Configuration so I can't use it.
USBCOMP is 8 by default, and 14 is not supported in this card.
swi_usbcomp.pl output was like below. https://zukota.com/sierra-wireless-em7455-how-to-enable-com-ports/
(It's EM7455 result, but EM7430 is Asia version of EM7455 so both are almost same card.)
swi_usbcomp.pl requires MBIM to work, and USBCOMP should be 8 to use with Windows. So I avoid to use 6, use 8.
It may be a problem the card is recognized under USB 3.0, but I can't change it by FakePCIID_XHCIMux.kext because this PC is Kaby Lake based that doesn't have EHCI.
I attached IORegistryExplorer output.
If EM7430 is not capable to use in High Sierra, I'll buy EM7330 instead.
If it is not chip related problem, I want to know the solution.
Any ideas?
