Frequently Asked Questions (FAQs)
5. Host-side drivers and tools
- Windows:
- CDC-ACM: Uses Microsoft-provided CDC drivers or vendor-supplied INF for virtual COM.
- Vendor/Bootloader: Often requires vendor-signed drivers or an INF mapping the VID/PID to a custom driver (e.g., USBSerial, libusb-based).
- Flashing tools: Vendor flashing utilities (e.g., SP Flash Tool for some MediaTek devices) or custom utilities using libusb.
- Linux/macOS:
- CDC-ACM: cdc_acm kernel driver exposes /dev/ttyACM*.
- Vendor: libusb-based tools or mode-switching via usb_modeswitch.
- For mass storage, kernel exposes block device when MSC is active.
- Cross-platform:
- libusb/libserialport-based utilities for flashing/debugging.
- DFU-util if device implements DFU class.
