Problem: After turning off the FT-710, does the USB cable still remain plugged in, and are COM3/COM4 (CAT and PTT interfaces) still present in Device Manager? However, the USB audio device (the sound card function of the FT-710) disappears, and only appears when the radio is turned back on. The RCForb app cannot find the audio device → no sound.
Purpose: To monitor the status of a specified USB audio device (e.g., a radio).
Function: After system login, RCForb is automatically started. When the radio loses power (the device disappears), RCForb automatically executes the shutdown-wait-restart repair process upon regaining power.
File name: RCForb_Auto_Recovery.ps1
Key ID: USB\VID_0D8C&PID_0013 (FT-710 virtual sound card hardware ID)
💾 Step 1: File preparation (create directories and scripts)
Create a directory: Create a folder named "Scripts" in the root of the C drive: C:\Scripts.
Create a script file: Copy the following 【script code】 into Notepad, and save it as C:\\Scripts\\RCForb_Auto_Recovery.ps1.
Log file: The script automatically creates a C:\\Scripts\\RCForb_Monitor.log file to record all operations after running.
Script code file:https://drive.google.com/drive/folders/1DL4ogPCfxkYwAtanDdwcy2alhhK-Z-Ek?usp=sharing
💻 Step two: Configuring the task scheduler.
Ensure that the script runs automatically with the highest privileges after you log in.
Open Task Scheduler: Search for and run "taskschd.msc".
In the "Actions" panel on the right, click "Create Basic Task (Name: RCFORB USB Audio Monitor)".
Trigger: Select "On Login".
Operation: Select "Start Program" and fill in the following information:
Options
Fill in the required information.
Program or script
powershell.exe
Add parameters (optional)
-Bypass Execution Policy -WindowStyle Hidden -File "C:\\Scripts\\RCForb_Auto_Recovery.ps1"
Modify permissions (important): After creating the task, right-click on it and select "Properties".
Check "Run with highest privileges"
In the "Security Options" section, select "Run only when a user logs in."
✅ Step 3: Function Verification (Power-on Test)
