Hi, I've just received my new home stereo, it's a Philips MC-M570, it have an USB port and provides some functionalities to it.
Under windows I can:
* use it like a PCM soundcard, without mixer controls;
* command the player application (MusicMatch Jukebox) with the
remote control of the stereo;
* see the song title that MusicMatch is playing on the stereo's
display.
On Linux, when I plug it in, usb hotplug loads the 'hid' and
'snd-usb-audio' drivers, the audio driver creates an /dev/sound/unknown
device (i'm using devfs), and this device works like /dev/dsp, and works
well. (I think that someone can update the web pages to show that this
works, and probably other gadgets from the same line from philips).
I'm looking for help on getting the other functionalities (remote
control and song titles). I suppose that this funcionalities is provided
by the HID it installs, but the hid driver didn't place any working
device under /dev, it creates the directory /dev/usb/hid/ but it's
empty.
I'm not a very good developer, but I think I can do this if I get the
right help, and this must be the right place to get this help.
Here is the /proc/bus/usb/devices lines that referer to this gadget:
