Robot USB-to-CAN interface evidence table
Host-to-CAN adapters compared at the protocol, timestamp, isolation, environmental and driver layers.
CAN, CAN FD, CANopen and device-specific application protocols are different layers. A USB adapter does not make host timing deterministic.

Values are transcribed from the linked sources and were checked on the date shown by each record. V = independently verified; M = manufacturer claimed; D = RCI derived; C = conflicting; U = unknown.
Interpretation rule
The condition belongs to the number.
RCI does not compute winners from this audit sample. The table’s purpose is to show what can be compared now, what requires a shared test, and which public fields are still missing.
