Emulator

Issue 4918 has been merged into this issue.

There doesn't seem to be any USB passthrough code in Dolphin, unfortunately, which would be required to make this work.

Overall, USB support in Dolphin would be fantastic. This would make games such as the first Rock Band playable (I think, not sure how far in it goes), such as with issue 4717. Rock Band does not detect guitar extensions because it only detects USB devices.

But if USB support is possible/added, could an emulated USB function exist as well? For example, support devices not originally supported such as X-Box 360 USB guitars (I personally own an xplorer for GH3 PC mods). Perhaps emulate the device then map buttons such as the emulated wiimote + extensions.

Obviously a low priority feature, but would be a nice to have none the less.

The original link no longer works.

I suspect the link is irrelevant anyway, since it'd just show Windows' view of the USB device. Rather than device specific support, it'd be much more sensible to do a form of USB passthrough, handing off an entire USB device to the IOS to handle. Then it should handle other peripherals, as mentioned.

It should be technically possible, since VM software has USB passthrough, but I'm not sure how much work it'd actually be. Perhaps looking into the VirtualBox code might provide some hints.
