Ok, here's the background. The Nomad is an mp3 player that connects via usb. There's a pretty cool library that you can use to write applications to talk to it. But there's another project that wanted to mount the jukebox and have it show up as a filesystem. I fixed up a couple minor things that changed about usb, and can query the device, see firmware revision etc in the /proc entries. To do the file stuff, njbfs was using code based on ftpfs. However, looking around I've discovered that there is a new project to standardize filesystem abstraction. I'll be checking out http://lufs.sourceforge.net/ over the weekend and seeing what I can do to fix up the driver. Thanks for the offer to help, once I get a better grounding in whats goig on, I may drop you a line with specific questions later. At least for now I have a path forward. -- Mental (Mental@NeverLight.com) This body. This body holding me.
