USBcanII HS/LS - CAN Bus USB Interface for Vehicle Electronics

VCI for simple communication tasks in engineering and development

CAN communication interfaces are an inexpensive alternative to diagnostic interfaces. The USBcanII HS/LS and the USBcan Pro 2xHS from KVASER are powerful hardware interfaces to be used for simple communication tasks in Engineering and Development.


Areas of Application

  • Simple communication tasks
  • Simulation
  • Test/validation
  • Applications in Development and Engineering


  • Active interface with its own microcontroller
  • 2 separate CAN channels with CAN high-speed and CAN low- speed (USBcanII HS/LS)
  • Communication with 2 channels Classic CAN or CAN FD (USBcan Pro 2xHS)
  • Easy to use
  • Lightweight and smart housing
  • Inexpensive solution


The programming interface from KVASER-Interfaces provides powerful communication mechanisms for CAN applications. Local buffering and preprocessing on the VCI result in high performance and a reduction of time-critical tasks for the PC.


The standardized programming interface provides applications with powerful multi-channel communication mechanisms with vehicle protocols, such as Diagnostics on CAN (ISO 15765) and UDS (ISO 14229). It also allows integration into diagnostic systems in accordance with ISO 22900 (MVCI). D-PDU API is also available as an option.


If your application requires more than one CAN bus at any time, the number of communication channels available at the PC can quickly be extended. This is simple to organize by combining the existing CAN interface with further CAN or EDIC® interfaces from Softing.


Combining USBcanII HS/LS with appropriate API software enables compact solutions for all kinds of communication applications. The KVASER programming interface thus supports reliable CAN communication on Layer2 in a simple way. The optional D-PDU API software makes communication channels with higher diagnostic protocols available to applications via the standardized API and thus relieves the application of standard tasks.
