Here are > the logs: Hm, comparing that to the traffic my device receives that may look somewhat shifted. Do you have CONFIG_MMU enabled? If yes, please try with MMU disabled. Also, maybe the buffer is not sufficiently aligned. Could you print the pointer address of buf? The buffer is statically allocated in drivers/net/usb/usbnet.c: static char rx_buf[4096]; This looks fishy. It should be allocated with dma_alloc() instead.
