I was hoping you would have the usb-serial driver bound to this and the other serial functions so you avoided this. But it's not really a problem, just a bit confusing. You have to adjust the tests a bit. > [ 6023.508210] qmi_wwan: probe of 2-6:1.1 failed with error -22 > [ 6023.509177] qmi_wwan: probe of 2-6:1.2 failed with error -22 > [ 6023.509871] qmi_wwan 2-6:1.3: cdc-wdm1: USB WDM device > [ 6023.510099] qmi_wwan 2-6:1.3 wwan1: register 'qmi_wwan' at > usb-0000:00:14.0-6, WWAN/QMI device, 02:b2:8c:7a:5d:55 > [ 6023.511420] qmi_wwan 2-6:1.4: cdc-wdm2: USB WDM device > [ 6023.511604] qmi_wwan 2-6:1.4 wwan2: register 'qmi_wwan' at > usb-0000:00:14.0-6, WWAN/QMI device, 58:2c:80:13:92:63 This is the only possible candidate. So you should do all testing on the wwan2 and /dev/cdc-wdm2 devices. > root@victor-laptop:~# qmicli -d /dev/cdc-wdm0 --device-open-version-info > --wds-noop > error: couldn't open the QmiDevice: Transaction timed out > root@victor-laptop:~# echo -e "ATI\r" > /dev/cdc-wdm0 > root@victor-laptop:~# cat /dev/cdc-wdm0 > [frozen] Please repeat this using the /dev/cdc-wdm2 instead.
