APDU driver init failed

[kmlob]

Steps to reproduce:

• Fresh and up-to-date installation of ArchLinux
• Install lpac via pacman OR build lpac from this repository
• run lpac

Observed:
"SCardEstablishContext() failed: 8010006A (Unknown error: 0xFFFFFFFF8010006A)
APDU driver init failed"

Comment:
My WWAN modem is detected by the system (mmcli command is working fine).

You'll need to specify the apdu driver backend using environment variables. lpac defaults to the sd card apdu driver, which I personally haven't gotten to work yet. Depending on the type of modem you have, try using the AT, QMI, or MBIM apdu driver.
