Corsair SCUF Valor Pro Support Discussion

Hey everyone!

So, it looks like some of us are running into a couple of snags with the Corsair SCUF Valor Pro controller. Specifically, the driver isn't recognizing it out of the box, and there are some rumble issues causing the controller to become unresponsive. Let's dive into these problems and see how we can tackle them.

Addressing the Driver Recognition Issue

The main problem here is that the Corsair SCUF Valor Pro isn't automatically recognized by the driver. This is because the vendor ID for Corsair isn't included in the wired ID table. Basically, the system doesn't know it's a Corsair controller when it's plugged in.

The Fix: Adding Corsair Vendor ID

The good news is that there's a straightforward fix for this. We need to add the Corsair vendor ID to the xone/transport/wired.c file. If you're familiar with making changes to driver files, here’s the snippet you’ll want to add:

+ { XONE_WIRED_VENDOR(0x1b1c) }, /* Corsair */

This line tells the driver to recognize devices with the vendor ID 0x1b1c as Corsair devices. By adding this, your system should now properly recognize your SCUF Valor Pro when it’s connected via a wired connection.

Step-by-Step Instructions

  1. Locate the File: Find the wired.c file in the xone/transport/ directory.
  2. Edit the File: Open the file with a text editor that has root privileges (since you'll be modifying system files).
  3. Add the Line: Insert the line { XONE_WIRED_VENDOR(0x1b1c) }, /* Corsair */ in the appropriate section (around line 548~570 as mentioned).
  4. Save the File: Save the changes.
  5. Rebuild the Driver: You'll likely need to rebuild and reinstall the driver for the changes to take effect. This usually involves running commands like make and sudo make install in the driver's source directory. Refer to the driver's documentation for the exact steps.
  6. Replug Your Controller: After the driver is updated, unplug and replug your Corsair SCUF Valor Pro. It should now be recognized correctly.

Important Note: Always exercise caution when modifying system files. Make sure you have a backup or a way to revert changes if something goes wrong.

Resolving the Rumble Issue

Now, let's talk about the rumble issue. It seems that a recent update increased the rumble limit, causing the controller to become unresponsive when the rumble is too strong. This can be super annoying, especially in the heat of gameplay.

The Problem: Overly Strong Rumble

The increased rumble limit is causing the controller to draw too much power or send signals that overwhelm the system, leading to unresponsiveness. The quick fix is to reduce the rumble limit back to a more stable level.

The Temporary Fix: Lowering the Rumble Limit

A temporary solution is to revert the rumble limit back to 100. This seems to stabilize the controller and prevent it from becoming unresponsive. Here's the change you can make:

- #define GIP_GP_RUMBLE_MAX 255
+ #define GIP_GP_RUMBLE_MAX 100

This change reduces the maximum rumble intensity, preventing the controller from going haywire.

Step-by-Step Instructions

  1. Locate the File: Find the gamepad.c file in the xone/driver/ directory.
  2. Edit the File: Open the file with a text editor that has root privileges.
  3. Modify the Rumble Limit: Change the line #define GIP_GP_RUMBLE_MAX 255 to #define GIP_GP_RUMBLE_MAX 100.
  4. Save the File: Save the changes.
  5. Rebuild the Driver: Again, you'll need to rebuild and reinstall the driver for the changes to take effect.
  6. Test Your Controller: Replug your controller and test the rumble function to see if it’s stable.

A Proper Solution: Differentiated Rumble Limits

While setting the rumble limit back to 100 works, it’s not ideal because it reduces the rumble intensity for all controllers, even those that can handle the higher limit. A more elegant solution would be to differentiate the rumble limits based on the controller model. However, this requires more in-depth knowledge of driver programming.

Ideally, the driver should check the controller's vendor and product IDs and apply the appropriate rumble limit. This would ensure that the SCUF Valor Pro gets a lower limit while other controllers can still use the full range.

Additional Tips and Considerations

  • Driver Updates: Keep your drivers updated. Sometimes, driver updates include fixes for compatibility issues and other bugs.
  • Check Connections: Ensure that your controller is properly connected. A loose connection can cause intermittent issues.
  • Power Supply: If you're using a wired connection, make sure your USB ports are providing enough power. Try using a different USB port or a powered USB hub.
  • Community Support: Don't hesitate to ask for help from the community. Forums and online groups are great resources for troubleshooting.

Wrapping Up

Dealing with compatibility issues can be a pain, but with a few tweaks, we can get the Corsair SCUF Valor Pro working smoothly. By adding the vendor ID and adjusting the rumble limit, you should be able to enjoy your gaming sessions without any frustrating interruptions. Remember to proceed with caution when modifying system files and always back up your data.

Hopefully, this guide helps you get your controller up and running. Happy gaming, everyone!
