Low-cost USB-CAN adapters based on the ITEK chipset (e.g., IT826xx) are widely used in hobbyist automotive diagnostics and small-scale industrial debugging, yet their real-time performance remains undocumented. This paper presents a systematic evaluation of the ITEK USB-CAN driver under various bus loads (10% to 95% utilization) and operating system configurations (Linux, Windows 10/11). We measure key metrics: minimum/average round-trip latency, frame jitter, and frame loss rate when using the vendor-provided driver vs. a reverse-engineered Linux socket-CAN driver. Our results show that with proper driver tuning (increasing kernel USB transfer buffers from 16 to 256 frames), the ITEK adapter achieves <1 ms latency at 500 kbit/s up to 60% bus load, but suffers >5% frame loss beyond 80% load without flow control. We provide a practical mitigation strategy — adaptive baudrate polling and userspace ring buffers — that recovers 99.97% of frames at 90% load. These findings allow developers to safely deploy ITEK adapters in non-critical monitoring applications, while quantifying their limitations for real-time control.
