Looklike issue is at ORANGE color text code in linux_usbfs.c file, it need a
cheque before memcpy "if (!priv->dev_desc) return error"
static int usbfs_get_device_descriptor(struct libusb_device *dev,
unsigned char *buffer) { 265 struct linux_device_priv *priv =
__device_priv(dev); /* return cached copy */ memcpy(
buffer, priv->dev_descriptor, DEVICE_DESC_LENGTH); return 0; }
