On some architectures such as arm64, siano chip based TV-tuner USB devices are not recognized correctly due to coherent memory allocation failure with the following error: [ 663.556135] usbcore: deregistering interface driver smsusb [ 683.624809] smsusb:smsusb_probe: board id=18, interface number 0 [ 683.633530] smsusb:smsusb_init_device: smscore_register_device(...) failed, rc -12 [ 683.641501] smsusb:smsusb_probe: Device initialized with return code -12 [ 683.652978] smsusb: probe of 1-1:1.0 failed with error -12 This is caused by dma_alloc_coherent(NULL, ...) returning NULL in smscoreapi.c. To fix this error, allocate the buffer memory for the USB devices via kmalloc() and let the USB core do the DMA mapping and free.
