Try compiling usbnet with DEBUG enabled. > Then look for debugging option of rndis support. > Hi Oliver, Thanks for your advice - I have enabled the "#define DEBUG" in usbnet.c and reconnected the device to the newly booted kernel. 'lsmod' shows that the correct modules are being loaded: Module Size Used by rndis_host 4523 0 cdc_ether 3394 1 rndis_host usbnet 14611 2 rndis_host,cdc_ether But the output from the kernel remains the same, and no additional ethernet interfaces are present. Have I enabled debugging correctly?
