While Fortinet does not provide an "exclusive" official driver for their USB console cables, they use the industry-standard FTDI FT232R chip. To get your cable working, you need the Future Technology Devices International (FTDI) Virtual COM Port (VCP) driver. Step 1: Download the Driver
Because Fortinet does not provide a proprietary installer, users must manually source the FTDI Virtual COM Port (VCP) drivers to make the device recognizable by modern operating systems. Step-by-Step Installation Guide
3. Exclusive Access Scenarios
- Console redirection: FortiOS locks the FT232R to prevent accidental shell access.
- Hardware security modules (HSM): Exclusive use for cryptographic operations.
- Debug vs. production modes: Different exclusivity behaviors.
4. Performance and Reliability Considerations
| Parameter | FT232R on FortiGate | Standard Linux (Ubuntu/CentOS) |
|-----------|----------------------|--------------------------------|
| Max baud rate | 115200 (limited by FortiOS agetty config) | 3 Mbps |
| Flow control | None (hardware CTS/RTS ignored) | Supported |
| Parity/stop bits | Fixed 8N1 (hardcoded in /etc/inittab-like config) | Fully configurable |
| Hot-swap detection | Delayed (5-10 sec) due to USB re-enumeration policy | Immediate |
| Logging | ftdi_sio logs suppressed by default (security hardening) | Verbose |
