LE-650H2 is the hardware-based USB analyzer, which can record a large amount of data on the HDD/SSD of the PC, display translation with each class decode, and measure VBUS power consumption. The analyzer automatically detects the High/Full/Low speed of USB2.0/1.1 and starts measuring by simply pressing the space bar of the PC. The low cost device of easy operation by connecting it to the USB port of the PC is useful for developing/debugging the firmware/driver and study purpose of USB standard.

*1: Bus Reset, Suspend, Disconnect are recorded under the following condition.
Bus Reset The SEO status of D+/D- signals is detected within a range between 2.5us and 139.8ms.
Suspend A non-communication period not in the SEO status is detected for 3ms or over.
Disconnect The SEO status of D+/D- signals is detected for 139.8ms or over.
Note: The USB device status may not coincide with the actual bus state of the applicable device at the time of USB cable connection or disconnection because the D+/D- signals will be unstable.
*2: Display a minus value when VBUS current flows from the device to the host.
*3: Need to have a USB2.0 port, which supports High-speed transfer.
