The host configures the device before Rockbox has handed the storage over, and mass storage allocated its buffer right then. On the recording screen the recording buffer still holds all free memory at that point and cannot shrink, so plugging in USB there panicked with "usb_storage_init_connection(): OOM". Recording closes, and frees its buffer, only on SYS_USB_CONNECTED, which the handover broadcasts. Playback does not hit this: its buffer gives memory up on request. The buffer is only needed to run commands, and commands already wait for the handover. So it is allocated, and the endpoint primed for the first command, in the notify event that both handover paths in usb.c send, or at once when the storage is already handed over. Until then the host's first command waits at the endpoint, NAKed. GET_MAX_LUN, which comes before the handover, is answered from the core's control buffer instead of the transfer buffer. Targets with static USB buffers are unchanged. Tested on a Samsung YP-CP3: USB plugged in on the recording screen, at boot and from the main menu, mounts, and files copied both ways keep their checksums.

Build Your Own Rockbox
1. Clone 'rockbox' from git (or extract a downloaded archive).
$ git clone git://git.rockbox.org/rockbox
or
$ tar xJf rockbox.tar.xz
2. Create a build directory, preferably in the same directory as the firmware/
and apps/ directories. This is where all generated files will be written.
$ cd rockbox
$ mkdir build
$ cd build
3. Make sure you have mips/m68k/arm-elf-gcc and siblings in the PATH. Make sure
that you have 'perl' in your PATH too. Your gcc cross compiler needs to be
a particular version depending on what player you are compiling for. These
can be generated using the rockboxdev.sh script in the /tools/ folder of the
source.
$ which arm-elf-eabi-gcc
$ which perl
4. In your build directory, run the 'tools/configure' script and enter what
target you want to build for and if you want a debug version or not (and a
few more questions). It'll prompt you. The debug version is for making a
gdb version out of it. It is only useful if you run gdb towards your target
Archos.
$ ../tools/configure
5. *ploink*. Now you have got a Makefile generated for you.
6. Run 'make' and soon the necessary pieces from the firmware and the apps
directories have been compiled, linked and scrambled for you.
$ make
$ make zip
7. unzip the rockbox.zip on your music player, reboot it and
*smile*.
If you want to build for more than one target, just create several build
directories and create a setup for each target:
$ mkdir build-fuzeplus
$ cd build-fuzeplus
$ ../tools/configure
$ mkdir build-xduoox3
$ cd build-xduoox3
$ ../tools/configure
