Hello, I recently became the owner a USB gadget that tracks movement via GPS and also tracks heart rate (it's a training device for athletes). This device comes with software that is windows only and...doesn't like up to it's potential (to put it politely). Being a programmer type and someone that prefers to use either linux or osx I quickly realized I should write my own software to use the gadget. Fortunately, the company that makes the device provides documentation to write drivers for the device (including a minimal example USB driver for win32). So then I looked around the net for a few open source things, such as open source drivers for the device or a Haskell library to help me start writing drivers for the gadget. I didn't see anything relevant after a few minutes of searching so I figure that means there isn't much. Did I miss a Haskell library for writing device drivers, specifically USB drivers? Would this be hard to write? I would prefer to support osx and linux at a minimum and I think it would be ideal to shoot for cross platform (win32, osx, linux and *bsd). I have this feeling that it could be done by writing platform specific wrappers using hsc2hs on each platform then bringing them together through a unified 'low' level Haskell api. The Haskell api would then be exposed as a module for application developers. Any thoughts? For the interested, the documentation I spoke of can be found here: http://www.garmin.com/support/commProtocol.html Thanks, Jason
