Support for QDL mode is already present for EM9191 modules, but the
non-QDL mode appears to be missing. Add it now.

I noticed an e-mail address discrepancy that git-send-email didn't
magically fix for me. No change otherwise.

Hi Frans,
the qcserial driver used in the usb-devices output above does not seem
to be built from the mainline qcserial.c with your patch applied as USB
interface 4 is ignored by the QCSERIAL_SWI layout.
To avoid potential side effects in case Sierra Wireless adds a vendor class
USB interface 2 not intended to be used with qcserial.c it might be best
to use a new QCSERIAL_SWI2 layout similar to what has been done in
their MBPL drivers mentioned here
https://forum.sierrawireless.com/t/rc7620-and-linux-driver/24308/ .
Regards,
Reinhard

Right, I will need to look into that then. I won't be able to access the devices for a couple of weeks, though. It might also just have been me no paying attention while testing. I'll get back to this.

I'll have a look at this too.
Thanks,
