Bus 003 Device 002: ID 05c6:9057 Qualcomm, Inc. SDXLEMUR-LITE-MTP _SN:XXXX With kernel 6.12.22 from debian unstable, when the device is connected to t= he computer by USB, it is seen as a network card and NetworkManager (1.52.0) r= uns DHCP to get a connection. With 6.13, this is not the case anymore. dmesg output with 6.12.22: rndis_host 3-2:1.0 eth0: register 'rndis_host' at usb-0000:00:14.0-2, RNDIS device, fc:dd:55:ff:ff:ff usbcore: registered new interface driver rndis_host rndis_host 3-2:1.0 enxfcdd55ffffff: renamed from eth0 dmesg output with 6.13: rndis_host 3-2:1.0 wwan0: register 'rndis_host' at usb-0000:00:14.0-2, Mobi= le Broadband RNDIS device, fc:dd:55:ff:ff:ff usbcore: registered new interface driver rndis_host rndis_host 3-2:1.0 wwxfcdd55ffffff: renamed from wwan0 As you can see with 6.12 it's seen as a Ethernet/RNDIS device, but with 6.13 it's seen as a Mobile Broadband RNDIS device This seems to be a regression from 67d1a8956d2d62fe6b4c13ebabb57806098511d8 Note that the device is establishing the connection itself and also act as a WiFi access point. The computer is not involved in the ppp connection at al= l. Can something be done? Kind regards, --=20 You may reply to this email to add a comment.
