Ldc101 Usb To Civ Driver Updated

Cause: CIV address mismatch.
Solution: Your Icom radio has a hex CIV address (default 0x5E for many). Ensure the LDC101 driver uses the same address. Use Icom’s CS-RADIO software to verify.

This guide covers the updated USB-to-CI-V (C-IV) driver for the LDC101 interface. This update resolves connectivity dropouts, improves Windows 11/ARM compatibility, and fixes "Device Descriptor Request Failed" errors.

Last Updated: [Current Date] Applies to: LDC101 (Low Distortion Converter) / CI-V compatible receivers & transceivers

Status: The updated driver is approved for deployment on standard Windows 10/11 workstations. No critical bugs detected in standard operating environments. ldc101 usb to civ driver updated

Before downloading, identify your chipset:

To confirm the updated driver is successfully installed and functional, perform the following checks:

Step 1: Device Manager Verification

Step 2: Driver Version Check

Option A — Kernel-supported device (CDC/usbserial or SocketCAN native):

  • If kernel recognizes it as a SocketCAN interface (e.g., can0), bring it up:
  • If not auto-created, check if vendor provides a kernel module (.ko) or udev rules; follow vendor instructions to install module (copy .ko, sudo depmod, sudo modprobe ).

    • Option B — libusb / userspace driver (e.g., slcan over /dev/ttyUSBx): Cause: CIV address mismatch

  • Adjust baud for the adapter’s command channel if required (e.g., 115200, 230400).

    • Permission note:

    The CI-V protocol often defaults to 9600 baud, but modern radios (like the IC-7300/9700) can handle higher speeds (19200 or 115200).
