DEVICE FOR MANAGING ERRORS ON A SERIAL UNIVERSAL BUS

摘要

Device for managing errors on a universal serial bus. The invention relates to electronic equipment comprising a host controller (11) that can control at least one universal serial communication port that can be connected to a plurality of peripherals (12, 13), characterised in that the host controller (11) comprises: means for establishing a connection, according to a pre-determined throughput, to a peripheral (12) connected to the communication port; means for measuring the throughput between the host controller (11) and the peripheral (12) and signalling an error if the measured throughput is lower than the pre-determined throughput; and means for establishing a new connection to the peripheral (12) according to the pre-determined throughput when the measuring means signal an error.
