A USB bulk write/read operation may fail with different errors: LIBUSB_ERROR_TIMEOUT if the transfer timed out (and populates transferred) LIBUSB_ERROR_PIPE if the endpoint halted LIBUSB_ERROR_OVERFLOW if the device offered more data, see Packets and overflows LIBUSB_ERROR_NO_DEVICE if the device has been disconnected another LIBUSB_ERROR code on other failures Current OpenOCD code is using the transfer size based error detection. Which may not always work. For example for LIBUSB_ERROR_OVERFLOW as libusb documentation says: "Problems may occur if the device attempts to send more data than can fit in the buffer. libusb reports LIBUSB_TRANSFER_OVERFLOW for this condition but other behaviour is largely undefined: actual_length may or may not be accurate, the chunk of data that can fit in the buffer (before overflow) may or may not have been transferred." This patch is refactoring code to use actual error return value for error detection instead of size.
