Key Features
Overview
Professional USB 2.0 Protocol Analysis Solution
The Lineeye LE-650H2 is a hardware-based USB protocol analyzer designed for engineers developing and debugging USB 2.0 devices and drivers. This compact aluminum-housed analyzer provides comprehensive monitoring capabilities for USB 1.1 and 2.0 communications, automatically detecting High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) operation modes.
Featuring continuous data recording up to 10GB on PC hard drives, the LE-650H2 enables engineers to capture extensive USB traffic without interrupting real-time analysis. The analyzer includes intelligent packet translation with class-specific decoding for standard device requests, descriptors, and various USB device classes including HID, Mass Storage, and Communications.
The device offers real-time VBUS power consumption monitoring with voltage, current, and power measurement capabilities. Advanced triggering and filtering functions allow precise capture of specific events, whilst statistical analysis features provide comprehensive transfer rate and data volume reporting. The LE-650H2's non-intrusive design connects seamlessly between USB hosts and devices via standard USB cables.
For enhanced functionality, engineers can upgrade to the LE-650H2-A Advanced model, which extends recording capacity to 40GB and supports high-speed VBUS logging capabilities.

Why Engineers Choose The Lineeye LE-650H2 USB 2.0 Protokollanalysator
Efficient USB Debugging
Long-Term Data Capture
Power Consumption Analysis
Der Lineeye LE-650H2 ist ein hardwarebasierter USB-Analysator, der große Datenmengen auf der Festplatte/SSD des PCs aufzeichnen, die Übersetzung bei jeder Klassendecodierung anzeigen und den VBUS-Stromverbrauch messen kann. Der Analysator erkennt automatisch die High/Full/Low-Geschwindigkeit von USB2.0/1.1 und startet die Messung durch einfaches Drücken der Leertaste des PCs. Das kostengünstige Gerät ist einfach zu bedienen, indem es an den USB-Anschluss des PCs angeschlossen wird, und eignet sich zum Entwickeln/Debuggen der Firmware/des Treibers und zum Studium des USB-Standards.
Questions and Answers
-
What Triggering Capabilities Does the LE-650H2 Offer for Capturing Specific Events?
The analyser supports up to 16 sequential triggers, which can be combined for complex captures:
- Packet triggers (specific token/data/handshake combinations)
- Error triggers (CRC/PID errors)
- Bus state triggers (reset/suspend/disconnect)
- External triggers via the 10-pin connector
- VBUS triggers on voltage/current thresholds
-
How Does the LE-650H2 Handle High-Speed USB Traffic Without Data Loss?
The LE-650H2 has 128MB of capture memory and streams the log to the PC over USB 2.0. The buffer absorbs bursts while data is written to the PC, and you can view and scroll the captured data during measurement.
-
What Filtering Options Are Available for Analyzing Large USB Datasets?
Log filters let you leave out SOF, IN-NAK, OUT-NAK, SETUP-NAK and PING packets, or keep only chosen addresses and endpoints, so captures stay smaller. Display filters hide the same kinds of packets. Search finds packet types, device requests and errors, and the statistics view shows transaction counts, bytes and average transfer rates.
-
Does the LE-650H2 Support USB Hub Analysis and Split Transactions?
Yes. The LE-650H2 analyses traffic through USB hubs and identifies split transactions (SPLIT packets), used when a high-speed hub carries full- and low-speed traffic. It also displays hub descriptors and requests.
-
What Are the PC System Requirements for Using the LE-650H2?
The LE-650H2 needs:
- Windows 7, 8.1, 10 or 11
- Core 2 Duo processor or later (Core i series recommended)
- 1GB RAM minimum
- USB 2.0 High-Speed port
- Enough disk space for data logging
It is powered from the PC's USB port (400mA maximum) and needs no separate power supply.
-
Can the LE-650H2 Measure USB Device Power Consumption?
Yes. The LE-650H2 monitors VBUS in real time, measuring voltage (0-8V), current (-0.9A to 1A) and power consumption of connected USB devices. Power data is shown graphically and can be logged alongside USB communication data.
-
What USB Speeds Does the LE-650H2 Support for Protocol Analysis?
The LE-650H2 analyses High-Speed (480Mbps), Full-Speed (12Mbps) and Low-Speed (1.5Mbps) USB 2.0/1.1 traffic and detects the speed automatically. Behind a hub running at a different speed, press the space bar to start measuring.
-
How Does Hardware-Based Analysis Differ From Software-Based USB Analyzers?
Hardware analysers like the LE-650H2 sit in line with the bus and capture traffic without affecting the communication. Software analysers run in the host's USB stack, can affect system performance and miss bus-level events. The LE-650H2 captures bus events including resets, suspend, disconnect and chirp.
-
What Is the Maximum Continuous Recording Capacity of the LE-650H2?
The standard LE-650H2 records continuously up to 10GB on the PC's hard drive or SSD. For longer recordings, the LE-650H2-A (Lineeye's Advance model) records up to 40GB and adds high-speed VBUS logging.
-
Which USB Device Classes Can the LE-650H2 Decode and Analyze?
The analyser decodes:
- Standard device requests
- HID class-specific requests
- Mass Storage/Bulk-Only Transport
- Communication Device Class (CDC)
- Audio class
- Printer class
- USBTMC
- Video class
- Hub class
- Wireless controller (Bluetooth HCI; may need a software update licence)
