This article introduces the kernel section of Bluetooth protocol stack bluez which implements the hid function in Linux. In Linux kernel, the implementation code of bluez for HID is in the/NET/Bluetooth/hidp folder, which includes three files: sock. C, core. C, and hidp. h. Bluez provides a socket interface by which user space programs control hid. The Protocol n

The progress of the record, compiled this post provided by the program, Sensortile can be used as a Bluetooth keyboard or mouse, which let me have a deep understanding of Bluetooth hid. Bluetooth more than 4.0 of the HID is based on Hid-over-gatt, if the Bluetooth IC support GATT, you can modify the firmware to achieve as a Bluetooth

Document directory 2.1 btd_register_adapter_driver 2.2 btd_register_device_driver This article analyzes the implementation of the hid protocol in the Bluetooth bluez protocol stack.1. Basic Concepts The hid protocol is used for human-machine input devices. The implementation code of hid in bluez is in the input directory under its root directory. The Blueto

Analysis of usb hid device interface protocol using ollydbg Author: tase tase@163.com Keywords: ollydbg, USB, hid, bus hound, Analysis tools: ollydbg, bus houndAnalysis object: a USB interface Flight Simulator Objective: To analyze the software that uses the usb hid device, "buckle" the data protocol of the HID device

BrieflyUSB protocol is widely used in the computer, when the external USB device is plugged in, it will be detected and initialized and started, and then follow the USB protocol to transmit data, supply is used for acquisition.USB devices are so diverse that they are divided into different device classes (Devices Class), and HID (Human Interface device class, man-machine interface) is a particularly important category. There are, of course, many other

Usb-hid is the abbreviation of human Interface device, which belongs to the Human-computer interaction operation device, such as USB mouse, USB keyboard, USB game joystick, USB touchpad, USB trackball, telephone dialing device, VCR remote control and so On. Tpyboard with Micropython In addition to the USB host feature, It can also be applied as a Usb-hid device, which focuses on if used as a mouse and Keybo

In USB, USB Host identifies a device through various descriptors, including device descriptors, configuration descriptors, interface descriptors, endpoint descriptors, string descriptors, and report descriptors. The USB report descriptor is a descriptor in the HID device. It is a complicated descriptor.　　 USB hid devices transmit data through reports, including input reports and output reports. The input r

1. When the host computer writes data to HID, the first byte transmitted by each packet is the write Data (out)of the report ID, and the upper and lower machine must be identical . Host Computer Configuration location: Next machine configuration location: 2. HID up-level machine when the data is returned, the first byte of each packet must also be read Data (in)the report ID, and in the lower machine,

1. Enumerate the USB STM32 as HID devices. 2. STM32 uses 3 endpoints, endpoint 0 for enumeration, endpoints 1 and 2 for data sending and receiving. 3. The endpoint length is 64, that is, a maximum of 64 bytes of data can be transmitted in a single pass. 4. STM32 obtains the data from the host computer and returns the data via USB and prints out the data. 5. The host computer program realizes the read and write control to the

Modify file: 1. Add vid PID to hid-ids.h 2. Add the following content to hid-multitouch.. C-> mt_devices []: { . Driver_data = mt_cls_default, Hid_usb_device (VID, pid) } 3, in the hid-core.c-> hid_have_special_driver [] add hid_usb_device (VID, pid) Certificate ----------------------- 4: Add Kernel configuration options: 5: 7: Kernel ------------------------- 8

1. Modification of descriptors: 1.1 Configuration Descriptor Modification: Modifies the size of the HID report Descriptor's bytes in the HID descriptor under the configuration descriptor. Modify the value to the number of bytes written by the HID report descriptor. 1.2 Specifies the endpoint, type (input, output), and data length of the endpoint used in the end

TEENSY practices for HID attacks Overview Traditionally, when you insert a CD/DVD in your computer or a USB device, you can run a file containing malicious content through automatic playback, however, when the automatic playback function is disabled, autorun. the inf file cannot be automatically executed. However, with TEENSY, you can simulate a keyboard and mouse. When you insert this custom USB device, the computer will recognize it as a keyboard,
