Abstract: Technologies for error handling of high speed input/output (I/O) data transfer is disclosed. Before a data transfer between an external I/O device (such as an SDIO card, other SDIO device, or USB device) and an I/O host controller of a compute device, tuning registers of the I/O host controller may be set. If the data transfer is unsuccessful, the compute device may access a table stored in the I/O host controller (or stored elsewhere in the compute device) which includes other sets of values of the tuning registers that may be used to successfully transfer data, and then attempt the data transfer with another set of values of the tuning registers. In order to initialize the table with sets of values that may be used, the compute device first performs test data transfers with various settings of the tuning registers.
