EXTRACTION OF OPERATING SYSTEM-SPECIFIC CHARACTERISTICS VIA A COMMUNICATION INTERFACE

摘要

Systems and methods for specifying extended descriptor information in a device accessed using a communication interface are disclosed. One method includes transmitting a request to a device from a host computing system, and receiving an extended capability descriptor identifying to the host computing system at least one extended descriptor set stored on the device. The extended capability descriptor identifies a minimum operating system version able to support a corresponding extended descriptor set.

主权项

1. A device comprising:
a communication interface; a memory configured to store a plurality of descriptors accessible by a host computing system communicatively connected to the communication interface, the plurality of descriptors including: an extended capability descriptor including an identification of a minimum operating system version able to support an extended descriptor set; and one or more extended descriptors included in the extended descriptor set, the one or more extended descriptors recognizable to a host computing system executing at least the minimum operating system version and useable to enumerate the device thereon.
