Description Łukasz Stelmach 2011-01-09 07:29:33 UTC 
The noticeable differences between iPod running Apple's firmware and Rockbox are vendor and model *strings* (IDs remain the same).

Rockbox also reveals the vendor of the USB-Storage interface chip to be TOSHIBA
$ cat /sys/devices/pci0000:00/0000:00:1d.7/usb2/2-3/2-3:1.0/host11/target11:0:0/11:0:0:0/vendor
TOSHIBA 

Rockbox runs on a variety of different hardware from different vendors.

Rockbox supports only (as of today) "storage" access.

Audio players with Rockbox firmware support in most cases much wider range of audio formats/codecs. In /.rockbox/codec directory one can find libraries for the following codecs: a52 aac adx aiff alac ape asap atrac3 au cook flac mod mp3 musepack nsf raac shorten sid smaf spc speex tta vorbis vox wav wav64 wavpack wma wmapro.

There are also encoders for the following formats: aiff mp3 wav wavpack.

This however may be different for other hardware platforms. Please check the upstream.

Supported playlist formats are m3u and m3u8 (UTF-8 with BOM)

Rockbox does not impose any restriction on directory structure as it scans the whole volume and builds it's own database. One can, however, disable scanning of particular directory and its children by placing an empty database.ignore file in it.

As of now (version 3.7) Rockbox seems to ignore eject command and it doesn't return to a normal operation upon receiving one so unmounting should suffice.

Although there has been a problem with directory structure depth (http://www.rockbox.org/tracker/task/10396) it has been resolved.

Rockbox equipped player (at least my iPod) may also act as a HID device with several "keyboard layouts" to choose from.
Comment 1 Martin Pitt 2011-02-10 02:58:06 UTC 
We actually already have a rule and info file for Rockbox:

ATTRS{product}=="Rockbox media player" , ATTRS{manufacturer}=="Rockbox.org" , ENV{ID_MEDIA_PLAYER}="rockbox"

Which looks like it should by and large fit for your player. Unfortunately you only gave the udev properties, not the USB attributes (which m-p-i matches on). If it doesn't work for you right now, can you please give the output of

/sbin/udevadm info --attribute-walk --path=/devices/pci0000:00/0000:00:1d.7/usb2/2-3

? (The path might have changed since you reported the bug).

Thank you!

For the record. These are data for the storage endpoint and everything above.

This is HID endpoint (Rockbox can emulate USB keybord)

Comment 3 Martin Pitt 2011-03-24 09:02:59 UTC 
This looks expected, although you unfortunately only sent the info for the raw usb device, not the block device on it. I just noticed that you actually did the same in the original bug. The ID_MEDIA_PLAYER attribute is *not* supposed to be on teh raw usb device, but on the associated block device, i. e. the part that gets mounted. Can you please check /sbin/udevadm info --query=all --name=sdb1 (or whatever your device name is when you plug it in)?
Comment 4 Martin Pitt 2011-04-19 02:56:38 UTC 
Łukasz, did you have a chance to run the command I asked for in the previous comment?

I've just installed media-player-info-13 (the latest available in Gentoo)
Comment 6 Martin Pitt 2011-04-21 04:26:40 UTC 
This correctly shows "E: ID_MEDIA_PLAYER=rockbox", so the m-p-i identification worked. What's actually not working with this then?
