Abstract

The invention discloses a data collection method and equipment, and is used for solving the problem in the prior art that all data of USB (Universal Serial Bus) equipment can not be normally collectedby collection equipment when the USB equipment capable of supporting a multi-Luns function is accessed into the collection equipment. The USB equipment sends the amount information of a logic partition by a first message preset through an HID ((Human Interface Device) protocol to the collection equipment, and the collection equipment determines the mapping way of the logic partition of the USB equipment according to the amount information of the logic partition; and the collection equipment notifies the USB equipment by a second message preset through the HID protocol to map all logic partitions to the collection equipment according to a determined mapping way of the logic partition, and obtains data in the mapped logic partition in the USB equipment. When the way of the invention is adopted, the collection equipment enables all logic partitions in the USB equipment to be mapped into the collection equipment through the determined mapping way, and the data in all logic partitions in the USB equipment is guaranteed to be collected.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for data collection. Background technique [0002] When a USB (Universal Serial Bus, Universal Serial Bus) device supporting the Mass Storage (mass storage) protocol is connected to the acquisition device through the USB interface on the acquisition device, the USB device will be mapped to a mobile hard disk drive letter in the acquisition device ; If there are multiple logical partitions in the USB device, that is, when the USB device supports multiple Luns (Logical Unit Number, logical unit number) functions, the USB device is mapped to a plurality of mobile hard disk drive letters in the acquisition device, wherein, A logical partition corresponds to a mobile hard disk drive letter, and different mobile hard disk drive letters are used to distinguish different logical partitions on the acquisition device. [0003] Usually, when a USB device supporti...
