cdc_mbim is modem-only. cdc_ncm is not. The reason you see cdc_mbim loaded is because of an oddity in the MBIM spec, allowing an USB interface to be both NCM and MBIM depening on the active altsetting. The cdc_mbim driver is therefore matching NCM interfaces to be able to detect this sort of dual function. But that's completely irrelevant to your ethernet adapter. MBIM cannot be used on an ethernet (it has no no L2 headers). By avoiding cdc_mbim, you can also drop the cdc_wdm dependency. > [ 9105.605635] cdc_ncm 2-1.1:1.5: MAC-Address: 9c:eb:e8:20:f5:5b > [ 9105.605640] cdc_ncm 2-1.1:1.5: setting rx_max = 16384 > [ 9105.605743] cdc_ncm 2-1.1:1.5: setting tx_max = 16384 > [ 9105.605991] cdc_ncm 2-1.1:1.5 usb0: register 'cdc_ncm' at > usb-0000:00:14.0-1.1, CDC NCM, 9c:eb:e8:20:f5:5b > [ 9105.680400] cdc_ncm 2-1.1:1.5 enx9cebe820f55b: renamed from usb0 See? This is only using cdc_ncm and will work fine even if cdc_mbim is unavailable. Bjørn
