I got a bit stuck.
We are using embedded linux on a target board to control the unit.
We now have the correct drivers installed.
When we plug the card in the following occurs.
usb 1-1: new high-speed USB device number 6 using zynq-ehci
usb 1-1: config 1 has an invalid interface number: 8 but max is 5
usb 1-1: config 1 has an invalid interface number: 10 but max is 5
usb 1-1: config 1 has an invalid interface number: 11 but max is 5
usb 1-1: config 1 has no interface number 1
usb 1-1: config 1 has no interface number 4
usb 1-1: config 1 has no interface number 5
option 1-1:1.0: GSM modem (1-port) converter detected
usb 1-1: GSM modem (1-port) converter now attached to ttyUSB0
option 1-1:1.2: GSM modem (1-port) converter detected
usb 1-1: GSM modem (1-port) converter now attached to ttyUSB1
option 1-1:1.3: GSM modem (1-port) converter detected
usb 1-1: GSM modem (1-port) converter now attached to ttyUSB2
qmi_wwan 1-1:1.8: cdc-wdm0: USB WDM device
qmi_wwan 1-1:1.8 wwan0: register ‘qmi_wwan’ at usb-zynq-ehci.0-1, WWAN/QMI device, e2:77:78:e0:2a:58
qmi_wwan 1-1:1.10: cdc-wdm1: USB WDM device
qmi_wwan 1-1:1.10 wwan1: register ‘qmi_wwan’ at usb-zynq-ehci.0-1, WWAN/QMI device, e2:77:78:e0:2a:58
Which is correct.
I can now talk to the unit (AT commands) on /dev/ttyUSB2
AT!gstatus?

OK

OK

I don’t understand the reply not implemented.
I see both wwan0 and wwan1 but neither become configured.
Am I missing something>
