    We read, that USB and CAN can't be used at the same time. What does it mean?

    Hello,

    The USB and CAN share a dedicated 512-byte SRAM memory for data transmission and reception, and so they cannot be used concurrently (the shared SRAM is accessed through CAN and USB exclusively).

    The USB and CAN can be used in the same application but not at the same time.

    Easy one, that s why I reply.
