Depends on what kind of peripheral you're talking about. If the OS supports it, and we have code to use that kind of device (e.g. joysticks, storage devices), then it should "just work." If you need to install Windows-only drivers to get your device to work, then it likely won't. We do have a guy working on getting raw HID support to underlie our device handling, which will improve things like USB device support and may even eventually allow installing some Windows-only drivers. But we're not there yet.
