DirtiHarri Posted January 11 Share Posted January 11 Problem: The FBV MKII Express pedal is not recognized by FBV control, nor Monkey 6 software after rebooting computer. This is caused by a number of programming errors from of the Line 6 software. Here is the main source of the problem: 1. Re-enumeration of the Device When the device is first connected, Windows attempts to identify it and assign the correct driver. Sometimes, the initial connection fails to establish the proper communication channel. Unplugging and replugging forces the system to re-enumerate the device, which is essentially a re-initialization process. This can give Windows another chance to properly recognize the device and install the correct driver (or reapply an already installed one). 2. Clearing Communication Errors If the device was experiencing a temporary communication issue, replugging it can clear that error, as the system will treat it as a new connection. This might happen if there was a timing issue or conflict when the device was initially detected, especially if other peripherals or drivers were also being initialized at the same time. 3. Driver Re-assignment Sometimes, Windows will default to a generic driver on the first connection, and replugging the device prompts the system to search for the correct driver again. If Line 6 software is installed and running, it can reassign the correct driver during this second detection attempt. 4. Windows USB Port Initialization USB ports can sometimes have issues with initializing devices correctly on the first connection. By unplugging and reconnecting, you force the USB port to reset and reinitialize, which might resolve any conflicts or errors in recognizing the device. A unplugging and plugging the device will temporarily fix this issue, however the problem will continue when the computer is turned off/rebooted. In order to avoid damaging cable and device female connector from repeated reconnection, I have found a temporary solution through command prompt. Step 1: Download Devcon Steps to Use DevCon: Download and Install DevCon: DevCon is part of the Windows Driver Kit (WDK), but you can also find standalone versions of the tool online. Here's how to get it from the Microsoft website: Visit: DevCon tool documentation. You might need to install the Windows Driver Kit (WDK) if you haven't already. Alternatively, you can search for the tool on trusted sources. Find the Device ID: To use DevCon, you need to know the Device ID of your FBV Express MKII. Open Device Manager. Right-click the FBV Express MKII device and select Properties. Go to the Details tab and select Hardware Ids or Device Instance Path from the dropdown. Copy the device's ID (for example, USB\VID_0E41&PID_5055&MI_00\9&1999b05a&0&0000). Use DevCon to Disable and Enable the Device: Open Command Prompt as Administrator (search for "cmd" in the Start menu, right-click, and select Run as Administrator). Use the following commands to disable and then re-enable the device: Disable the device: devcon disable "DeviceID" - Replace "DeviceID" with the Device ID you copied earlier. - Replace "devcon" with the "directorypath/devcon.exe" Re-enable the device: devcon enable "DeviceID" This sequence mimics unplugging and replugging the device by disabling it and then re-enabling it without needing to physically disconnect it. Notes: If the devcon command does not work, you need to locate the devcon.exe directory and use the directory in place of the "devcon" command in the command prompt. Once this command is successfully ran, you will notice the FBV MKII Express in device manager will not run correctly, nor will FBV control detect the device. This causes the driver to no longer be detected by windows. Step 2: reboot computer Windows will automatically reinstall driver and re-enumerate the device. The device should now be detected by FBV control and monkey 6. Suggestions to line 6: Please create a proper .inf file for the FBV MKII Express rather than having it use a generic usb audio driver to avoid FBV control and monkey 6 not detecting the device because of re-enumeration problems after shutdown/reboot sequence.
