  • How do I install Kvaser drivers on my Macbook?

    We do not have drivers for Apple Macbooks or desktop computers.  We have drivers for Windows and Linux.  You can run a virtual machine on your Apple computer running Linux or Windows if your machine is based on an Intel x86 or x64 architecture.  This will not currently work with the M1 based Apple computers.

  • If I change Kvaser USB interfaces, do I need new Drivers and SDK?

    All Kvaser interfaces share the same Drivers and SDK package. A software that has been written for the Kvaser Leaf light or Kvaser Leaf Pro can often be used with Kvaser U100 and Kvaser U100P without any changes. (But it is never wrong to update/recompile the software with the latest Kvaser SDK).

  • Adding Virtual Channels

    The two virtual channels that comes with the driver installed are connected, working as for example two Leafs connected by a loopback cable.

    If you want more virtual channels, or channels not connected, you can use the Add Hardware Wizard to add a second pair. These will be connected to each other, but not to the first pair.

    1. Press Windows + R, and type hdwwiz and click OK
    2. Click Next, and manual install. Select CAN Hardware (Kvaser) and Next
    3. Scroll down to Kvaser Virtual CAN driver, and then Next until it finishes.

    You should now have an additional pair of virtual channels ready to use.
