I'm pretty sure this is the wrong list, but maybe some clever people here can redirect me...
I have a "RCA RS2100 Bookshelf Audio System" http://www.woot.com/blog/viewentry.aspx?id=2744 This is radio/CD/mp3 player... PLUS it can stream audio wirelessly. You plug a USB device into your PC and you can remote control what gets played from the RS2100 remote control ("Wireless Musiclink").
BUT only with Windows Media Center.
When I plugged the device in it appears to look like 3 devices; a HID, an audio device and something else I can't remember (I'm not at that machine at the moment). My feeling is that the HID is used to inject commands from the RS2100 (eg "play track <x>"), the audio device is for streaming and the third device is feedback for the remote display.
The question I have... how can I reverse engineer the protocol used so that I can make this work on my CentOS machine? (I don't want to run a Windows instance just for remote audio!). Any hints, tips, pointers etc much appreciated.
Thanks!
