Thoughts on a new driver

Hey folks,

I have a USB device that isn't support in linux. So, of course, I've been
toying with the idea of writing a driver for it.

It's a Logitech Harmony 880 universal remote. I'm thinking it's probably a
good candidate for a user-space libusb driver. The way it operates is pretty
simple: you go to a website, configure how your system is setup, it
generates a binary file you then download and use the proprietary mac/win
software to transfer this binary image to the device. The device reloads and
has it's new configuration.

So at a relatively blind guess, I'm thinking a few setup commands and a data
transfer is about all there is to this thing. That is of course without
having used any USB sniffers or anything.

Which leads me to my question. I'm not entirely sure where to start. Am I
right in thinking this is a good candidate for libusb? If so, I've glanced
at the libusb developers guide, but is there a way to figure out what this
thing expects? Should I start by trying to get some hardware docs from
Logitech (who given they supposedly have a linux driver "in the works" I
suspect is unlikely to give me anything), or is this thing (seemingly)
simple enough to figure out?

What's odd is when I plug it in, it declares itself a HID device:

      bInterfaceClass         3 Human Interface Devices
      bInterfaceSubClass      0 No Subclass
      bInterfaceProtocol      0 None

uhci_hcd and address 2
Feb  1 22:44:05 rider kernel: HID device not claimed by input or hiddev
Feb  1 22:44:05 rider kernel: usbcore: registered new driver usbhid
Feb  1 22:44:05 rider kernel: drivers/usb/input/hid-core.c: v2.6:USB HID
core driver

I may end up getting some time to poke at this in a month or so, so I
thought I'd starting thinking/asking about this now...
