K2L’s OptoLyzer® Studio software has been extended to work with the Kvaser Hybrid 2xCAN/LIN interface, among other Kvaser devices. The latest version of K2L-branded OptoLyzer® Studio ( OLS V1.7.1 ) now supports the Kvaser Hybrid 2xCAN/LIN, Kvaser Hybrid Pro 2xCAN/LIN, USBcan Pro 2xHS v2, Leaf Light HS v2, Leaf Pro HS v2 and Leaf Professional LIN, adding to existing support for Kvaser’s Leaf CAN to USB range. In theory, USB 2.0 includes USB 1.1 and USB 1.0. The USB OTG controller should be capable of it. Might be that the OTG controller is not capable of low-speed. The StarterWare USB Host MSC driver might have been written just for USB 2.0 high speed. I vaguely rememeber the low and full speed handling is slightly different. The Kvaser Leaf Light HS v2 is a direct replacement for the older model. It is compatible with the same software and simply requires the most recent Kvaser driver. For more information, please contact us. The Kvaser Leaf Light supports full speed USB interface for CAN with high performance at a low cost.
