Key Features
Overview
Professional USB 2.0 Protocol Analysis with Advanced Features
The Lineeye LE-650H2-A represents the premium tier of USB protocol analyzers, delivering comprehensive analysis capabilities for USB 2.0 development and debugging. This hardware-based analyzer excels at capturing large volumes of USB data whilst providing real-time visibility into communication patterns and power consumption.
Recording up to 40GB of measurement data directly to your PC's HDD or SSD, the LE-650H2-A enables extended monitoring sessions essential for intermittent fault diagnosis. The analyzer automatically detects High/Full/Low speed USB 2.0/1.1 communications and begins measurement with a simple spacebar press, making it accessible for engineers at all experience levels.
Enhanced Analysis Capabilities
Unlike its standard counterpart the LE-650H2, the LE-650H2-A offers quadruple the storage capacity and high-speed VBUS logger functionality. The device provides detailed class-level decoding for multiple USB device classes including Mass Storage, HID, Audio, and Communication devices.
The compact aluminium housing reduces electromagnetic interference whilst maintaining portability. For engineers developing USB devices, host controllers, or embedded systems, the LE-650H2-A delivers the analysis depth required to identify timing issues, protocol violations, and power consumption anomalies that software-based analyzers typically miss.

Frequently Asked Questions
Have a Question?
-
What technical support and documentation is available for the LE-650H2-A?
Lineeye provides comprehensive documentation including detailed user manuals, quick start guides, and software libraries for custom application development. The analyzer includes Windows and Linux API libraries for integration into automated test systems. Debug Store offers additional technical support and can provide guidance on optimal analyzer configuration for specific USB development requirements.
-
How easy is it to set up and use the LE-650H2-A for first-time users?
Setup is straightforward - simply connect the analyzer between your USB host and device, install the included PC software, and press the spacebar to begin measurement. The analyzer automatically detects USB speeds and begins recording immediately. The software provides intelligent packet parsing, color-coded display customization, and extensive search functions to quickly locate specific events within captured data.
-
What external connectivity options does the LE-650H2-A provide?
The analyzer includes 4 external trigger inputs and 4 external trigger outputs via a 10-pin connector (TTL/LVTTL levels), enabling synchronization with oscilloscopes, logic analyzers, and other test equipment. This allows correlation of USB protocol events with external system behaviour and supports complex multi-instrument measurement setups for comprehensive system analysis.
-
Does the LE-650H2-A work with USB 3.0 devices and connections?
The LE-650H2-A is specifically designed for USB 2.0 analysis and supports High-Speed (480Mbps), Full-Speed (12Mbps), and Low-Speed (1.5Mbps) communications. While USB 3.0 devices often maintain USB 2.0 compatibility, the analyzer cannot capture SuperSpeed USB 3.0 traffic. For comprehensive USB 3.0 analysis, consider dedicated USB 3.0 protocol analyzers available at Debug Store.
-
What trigger and filter options are available on the LE-650H2-A?
The analyzer supports comprehensive triggering on specific addresses/endpoints, packet types, errors (CRC/PID), data patterns up to 8 bytes, bus states (Reset, Suspend, Disconnect), external signals, and VBUS voltage/current thresholds. It can execute up to 16 sequential trigger actions including measurement stop and external trigger output. Filter functions allow selective recording and display of SOF, IN-NAK, OUT-NAK, SETUP-NAK, and PING packets with multiple address/endpoint combinations.
-
Can the LE-650H2-A monitor VBUS power consumption in real-time?
Yes, the analyzer features integrated VBUS measurement capabilities with ±1% accuracy for both voltage (0-8V range) and current (-0.9A to 1A range). The VBUS logger mode can record power data at intervals from 0.1ms to 1s, storing up to 2GB of power measurement data. This enables correlation of power consumption patterns with specific USB communication events and identification of power-related issues.
-
What USB device classes does the LE-650H2-A decode automatically?
The analyzer provides detailed class-level decoding for Mass Storage (SCSI, ATAPI, SFF-8070i), Human Interface Device (HID), Audio, Video, Communication (CDC), Hub, Printer, USBTMC, Network, Mobile, and Wireless Controller classes. It also decodes standard USB descriptors and device requests, presenting complex USB communication in human-readable format rather than raw hexadecimal data.
-
How does the 40GB recording capacity benefit USB development projects?
The 40GB capacity allows engineers to capture extended USB communication sessions lasting hours or days, which is crucial for identifying intermittent faults and rare communication failures. This capacity supports continuous logging without data loss, enabling comprehensive analysis of device behaviour under various operating conditions. The data is stored efficiently on your PC's HDD or SSD with configurable file sizes up to 2GB each.
-
What makes the LE-650H2-A different from software-based USB analyzers?
The LE-650H2-A is a hardware-based analyzer that operates independently from your host system, providing non-intrusive monitoring without affecting system performance. Unlike software analyzers that rely on filter drivers and can cause system instability, the LE-650H2-A captures low-level bus events including reset sequences, suspend/resume cycles, and timing violations that software analyzers cannot detect. This makes it essential for debugging host controller issues and embedded USB implementations.
