USB Passthrough

Since, Dolphin has the ability to passthrough USB HID devices designed for use with Wii software. enables USB passthrough for all devices. This gives emulated Wii software full control of a hardware device connected to your PC. This is very useful for devices not currently emulated by Dolphin and games that highly depend on extra hardware.

Linux
Linux support does not require any special drivers. However, a udev rule must be created to allow access to the devices. Note, the Vender ID and Product ID SHOULD be verified from the device itself before creating the rule.

1. Paste the following into /etc/udev/rules.d/52-dolphin.rules (/lib/udev/rules.d/52-dolphin.rules if making a package). Do not forget to replace the XXXX with the appropriate Vendor and Product IDs.

2. Reload udev rules with:

3. Reinsert the accessory.

Single Interface Devices
Download and open Zadig, then:

1. In the "Options" menu in Zadig, make sure "List All Devices" is enabled.

2. Look through the devices for the device to passthrough.

3. On the right column, select "libusbk" then click "Replace Driver". Select "Yes" to modify the system driver.

Multi Interface Devices
More Microphone, Wii Speak, and USB Camera Passthrough, installing over the composite parent device is required.

1. In the "Options" menu in Zadig, make sure "List All Devices" is enabled and "Ignore Hubs or Composite Parents" is disabled.

2. Look through the composite parent of the device you wish to passthrough.

3. On the right column, select "libusbk" then click "Replace Driver". It may warn you that you're modifying a kernel driver, but, this is normal. Select "Yes" to modify the kernel driver.

Uninstalling Dedicated Driver
If for some reason you wish to restore the default driver to the device, open up "Device Manager." In the last, expand "Universal Serial Bus Devices" and find the device you wish to restore. Uninstall the device, then unplug the device and plug it back in. It will now be restored to its original state.

usbdk driver
usbdk provides the ability to simply install a driver and it will handle the rest. Despite being easier to use, usbdk is not recommended due to instability issues. Regardless, Dolphin still supports using the latest x64 usbdk driver.

macOS
While this can be done in macOS, there is currently no easy to use guide for it. A modified variant of the Native GameCube Adapter for Wii U guide should work, but what needs to be changed is not immediately apparent.

Android
This feature is not supported on Android.
