SIGNALING TO A PERIPHERAL VIA IRREGULAR READ OPERATIONS

摘要

A peripheral (120) communicates with a host (302) according to a protocol such as USB. In case a user of the host is restricted by an operating system (114) of the host from sending certain information to the peripheral (120), a pattern of protocol commands that includes the one or more read commands is defined that sends the information despite the restriction. Preferably, all the protocol commands are read commands.
