What kind of devices?  Almost all devices interact to the user through
some other interface (tty device, video device, sound device, block
device, etc.)  Very few interact through a "raw" usb interface (some
camera being the exception, using gphoto2 to talk to libusb to talk to
the camera.)

It's in theory a really generic device that can be used to test all sorts of USB "device" applications. At the moment it's pretending to be a new flavor of digital still camera. It has a vendor ID of 0x10C9 and a product ID of 0xeff0, but since it's a test device that information happens to also be configurable on the fly. Even more specifically, it's a board made by Zuken in Japan. So what I'm trying to figure out is how, on the Linux "host" side, I can debug a random "device" that I plug in.
