USB
A widely used industry standard that governs the connection, communication, and power supply between computers and external devices.
Timeline (last 90 days)
USB stands for Universal Serial Bus.
Through USB connection and debugging protocols (iOS's XCTest framework or Android's UIAutomator), external programs can directly read the accessibility tree without image recognition.
The standard starting point for reverse engineering a USB hardware device is to observe the descriptors, HID reports, and control endpoints that the device exposes on the USB interface.
USB audio class device protocols are relatively standardized, making them relatively easy to reverse engineer within the hardware domain; devices using proprietary encrypted protocols or complex firmware interactions are significantly more difficult.
The core skills required to enter chip design include object-oriented programming ability, hardware description languages (Verilog/VHDL/SystemVerilog), backend and analog design tools, and knowledge of protocols such as USB and PCI.
The I/O performance and latency of the USB protocol is inferior to native SATA or SAS direct connections, and bandwidth is shared when multiple drives are reading and writing simultaneously.
Jornada P6 uses BLE HID for daily wireless connectivity and USB for charging, firmware, debugging, and backup HID.
