Understanding the Dell WD19TB Firmware Upgrade Issue

When attempting to upgrade the firmware on a Dell WD19TB Thunderbolt Dock using fwupd, users may encounter a specific error message: failed to write-firmware: wrong proxy GType, got FuDellDockEc and expected FuHidDevice. This error typically indicates a mismatch in the expected and actual device proxy types during the firmware update process. To grasp this issue fully, it's essential to understand the underlying firmware update mechanism and how fwupd interacts with different device types.

The Role of `fwupd` in Firmware Updates

fwupd (Firmware Update Daemon) is a widely used open-source tool designed to manage and deploy firmware updates on Linux systems. It supports a vast array of devices, including laptops, peripherals, and docking stations. fwupd streamlines the update process by communicating with the device's firmware interface, fetching updates from trusted sources, and applying them in a controlled manner. This helps ensure the system and its components remain secure and perform optimally.

Decoding the "Wrong Proxy GType" Error

The "wrong proxy GType" error suggests that the system is trying to use an incorrect device handler during the firmware update. In the context of the Dell WD19TB dock, this often means that the system is attempting to use a Human Interface Device (HID) handler when it should be using a Dell Dock-specific handler (FuDellDockEc). This mismatch can occur due to various reasons, such as incorrect device identification, driver issues, or conflicts within the fwupd framework itself.

Key Factors Contributing to the Issue

Several factors can contribute to the Dell WD19TB firmware upgrade failure. Identifying these can help you tailor your troubleshooting approach:

Device Recognition: The system may not correctly recognize the dock and its various sub-components, leading to the wrong driver or handler being invoked.
Driver Conflicts: Conflicting drivers or incomplete installations can interfere with the communication between fwupd and the dock's firmware interface.
fwupd Bugs: While fwupd is generally reliable, bugs or compatibility issues within the software itself can sometimes cause unexpected errors.
USB Subsystem Issues: Problems within the USB subsystem, such as incorrect device enumeration or power delivery issues, can also lead to firmware update failures.

Step-by-Step Troubleshooting Guide

To effectively resolve the Dell WD19TB firmware update issue, follow these detailed troubleshooting steps. Each step is designed to address potential causes and guide you toward a solution.

1. Verify Basic Connections and Power

Before diving into complex troubleshooting, ensure the basics are covered. This includes:

Physical Connections: Check that the Thunderbolt cable connecting the dock to your laptop is securely plugged in at both ends. A loose connection can disrupt the firmware update process.
Power Supply: Confirm that the dock's power adapter is correctly connected and functioning. A power cycle of the dock (unplugging the power adapter for a few minutes and then plugging it back in) can sometimes resolve connection issues.
Peripheral Devices: Disconnect all peripherals (USB devices, monitors, etc.) from the dock. This eliminates potential conflicts that these devices might introduce during the update process.

2. Check fwupd Version and Configuration

Using the latest version of fwupd is crucial, as it often includes bug fixes and improvements that address compatibility issues. Additionally, checking the configuration can reveal potential problems.

fwupd Version: Verify the installed version using the command:
```
sudo fwupdmgr --version
```
Ensure you are running a recent version (ideally 2.0.18 or later). If not, update fwupd using your distribution's package manager (e.g., pacman for Arch Linux, apt for Debian/Ubuntu).
fwupd Configuration: Examine the fwupd configuration for any custom settings that might interfere with device handling. Key configuration files are typically located in /etc/fwupd/. Look for any unusual entries or settings that deviate from the default configuration.

3. Examine Device Identification

Incorrect device identification is a common cause of the "wrong proxy GType" error. Verify how your system recognizes the Dell WD19TB dock.

List Devices with fwupdmgr: Use the following command to list all devices recognized by fwupd:
```
fwupdmgr get-devices --filter=~internal
```
This command filters out internal devices, focusing on external peripherals like the dock. Look for the Dell WD19TB dock in the list and note its Device ID and GUIDs.
Check USB Device Tree: Use the lsusb command to inspect the USB device tree. This can help identify how the system enumerates the dock and its sub-components:
```
lsusb -t
```
Look for entries related to the Dell WD19TB dock (Vendor ID 0x413C) and its various hubs and controllers. Ensure that all components are correctly enumerated.

4. Analyze fwupd Logs

Detailed logs from fwupd can provide valuable insights into the root cause of the error. Enabling verbose logging and examining the output can reveal device handling issues or other underlying problems.

Enable Verbose Logging: Modify the fwupd configuration to enable verbose logging. Use the following command:
```
fwupdmgr modify-config "VerboseDomains" "*"
```
This command sets the VerboseDomains configuration option to *, enabling verbose logging for all domains.
Reproduce the Issue: Attempt the firmware upgrade again using the command:
```
fwupdmgr upgrade
```
Examine System Journal: After reproducing the issue, collect the verbose daemon logs from the system journal using the command:
```
journalctl -b -u fwupd.service
```
Analyze the logs for error messages, particularly those related to device proxy types (FuDellDockEc vs. FuHidDevice), device enumeration, or communication failures. The logs may pinpoint the exact component or process causing the issue.

5. Manually Trigger Firmware Update for Specific Components

Sometimes, the overall firmware update process fails due to issues with a specific component within the dock. Manually targeting individual components for updates can help isolate and resolve the problem.

Identify Components: Use the fwupdmgr get-devices --filter=~internal command to list the dock's components, such as the RTS5413 hub, RTS5487 hub, VMM5331 controller, and Thunderbolt controller. Note their Device IDs.
Update Individual Components: Use the fwupdmgr update command with the --device option to target specific components. For example:
```
sudo fwupdmgr update --device <Device ID>
```
Replace <Device ID> with the actual Device ID of the component you want to update. Repeat this process for each component, checking for errors after each attempt. This can help identify if a particular component's firmware is causing the overall update failure.

6. Rule Out USB Subsystem Issues

USB subsystem problems can lead to device recognition and communication issues. Troubleshooting the USB subsystem involves several steps:

Kernel Messages: Check the kernel messages for any USB-related errors. Use the dmesg command and filter for USB-related entries:
```
dmesg | grep USB
```
Look for error messages such as device enumeration failures, timeouts, or power-related issues.
USB Reset: Try resetting the USB subsystem. This can sometimes resolve enumeration issues. The exact method varies depending on your system configuration, but a common approach involves unloading and reloading the usbcore module:
```
sudo modprobe -r usbcore
sudo modprobe usbcore
```
Caution: Resetting the USB subsystem can disrupt other USB devices. Ensure you have a stable system before attempting this.
USB Quirks: Some devices require specific USB quirks to function correctly. Consult your distribution's documentation or online forums for any recommended quirks for the Dell WD19TB dock.
